Radio Board Block Summary3.1 IntroductionThis section gives a short introduction to the blocks of the BRD4151A Radio Board.3.2 Radio Board Block DiagramThe block diagram of the EFR32MG Radio Board is shown in the figure below.Figure 3.1. BRD4151A Block Diagram3.3 Radio Board Block Description3.3.1 Wireless MCUThe BRD4151A EFR32 Mighty Gecko Radio Board incorporates an EFR32MG1P232F256GM48 Wireless System on Chip featuring 32-bit Cortex-M4 with FPU core, 256 kB of flash memory and 32 kB of RAM and a 2.4 GHz band transceiver with output power up to 19.5 dBm. For additional information on the EFR32MG1P232F256GM48, refer to the EFR32MG1 Data Sheet.3.3.2 LF Crystal Oscillator (LFXO)The BRD4151A Radio Board has a 32.768 kHz crystal mounted.3.3.3 HF Crystal Oscillator (HFXO)The BRD4151A Radio Board has a 38.4 MHz crystal mounted.3.3.4 Matching Network for 2.4 GHzThe BRD4151A Radio Board incorporates a 2.4 GHz matching network which connects the 2.4 GHz TRX pin of the EFR32MG1 to the one on-board printed Inverted-F antenna. The component values were optimized for the 2.4 GHz band RF performace and current con-sumption with 19.5 dBm output power.For detailed description of the matching network, see Chapter 4.2.1 Description of the 2.4 GHz RF Matching.| Smart. Connected. Energy-friendly.Rev. 1.7 | 33.3.5 Inverted-F AntennaThe BRD4151A Radio Board includes a printed Inverted-F antenna (IFA) tuned to have close to 50 Ohm impedance at the 2.4 GHz band.For detailed description of the antenna see Chapter 4.5 Inverted-F Antenna.3.3.6 UFL ConnectorTo be able to perform conducted measurements, Silicon Labs added an UFL connector to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.Note: By default the output of the matching network is connected to the printed Inverted-F antenna by a series component. It can be connected to the UFL connector as well through a series 0 Ohm resistor which is not mounted by default. For conducted measurements through the UFL connector the series component to the antenna should be removed and the 0 Ohm resistor should be mounted (see Chapter 4.2 Schematic of the RF Matching Network for further details).3.3.7 Radio Board ConnectorsTwo dual-row, 0.05” pitch polarized connectors make up the EFR32MG Radio Board interface to the Wireless Starter Kit Mainboard. For more information on the pin mapping between the EFR32MG1P232F256GM48 and the Radio Board Connector, refer to Chapter 2.2 Radio Board Connector Pin Associations.4. RF Section4.1 IntroductionThis section gives a short introduction to the RF section of the BRD4151A.4.2 Schematic of the RF Matching NetworkThe schematic of the RF section of the BRD4151A Radio Board is shown in the following figure.U1BPath Inverted-F Antenna2.4 GHz Matching Figure 4.1. Schematic of the RF Section of the BRD4151A4.2.1 Description of the 2.4 GHz RF MatchingThe 2.4 GHz matching connects the 2G4RF_IOP pin to the on-board printed Inverted-F Antenna. The 2G4RF_ION pin is connected to ground. For higher output powers (13 dBm and above) beside the impedance matching circuitry it is recommended to use additional harmonic filtering as well at the RF output. The targeted output power of the BRD4151A board is 19.5 dBm. As a result, the RF output of the IC is connected to the antenna through a four-element impedance matching and harmonic filter circuitry.For conducted measurements the output of the matching network can also be connected to the UFL connector by relocating the series R1 resistor (0 Ohm) to the R2 resistor position between the output of the matching and the UFL connector.4.3 RF Section Power SupplyOn the BRD4151A Radio Board the supply pin of the RF Analog Power (RFVDD) is connected directly ot the output of the on-chip DC-DC converter while the supply for the 2.4 GHz PA (PAVDD) is provided directly by the mainboard. This way, by default, the DC-DC converter provides 1.8 V for the RF analog section, the mainboard provides 3.3 V for the PA (for details, see the schematic of the BRD4151A).4.4 Bill of Materials for the 2.4 GHz MatchingThe Bill of Materials of the 2.4 GHz matching network of the BRD4151A Radio Board is shown in the following table.Table 4.1. Bill of Materials for the BRD4151A 2.4 GHz 19.5 dBm RF Matching Network | Smart. Connected. Energy-friendly.Rev. 1.7 | 54.5 Inverted-F AntennaThe BRD4151A Radio Board includes an on-board printed Inverted-F Antenna tuned for the 2.4 GHz band. Due to the design restric-tions of the Radio Board the input of the antenna and the output of the matching network can't be placed directly next to each other. Therefore, a 50 Ohm transmission line was necessary to connect them. The resulting impedance and reflection measured at the output of the matcing network are shown in the following figure. As it can be observed the impedance is close to 50 Ohm (the reflection is better than -10 dB) for the entire 2.4 GHz band.Figure 4.2. Impedance and Reflection of the Inverted-F Antenna of the BRD4151A| Smart. Connected. Energy-friendly.Rev. 1.7 | 65.

BRD4151A Bottom ViewMechanical DetailsRev. 1.7 | 7EMC Compliance 6. EMC Compliance6.1 IntroductionCompliance of the fundamental and harmonic levels is tested against the following standards:• 2.4 GHz:•ETSI EN 300-328•FCC 15.2476.2 EMC Regulations for 2.4 GHz6.2.1 ETSI EN 300-328 Emission Limits for the 2400-2483.5 MHz BandBased on ETSI EN 300-328 the allowed maximum fundamental power for the 2400-2483.5 MHz band is 20 dBm EIRP. For the unwan-ted emissions in the 1 GHz to 12.75 GHz domain the specified limit is -30 dBm EIRP.6.2.2 FCC15.247 Emission Limits for the 2400-2483.5 MHz BandFCC 15.247 allows conducted output power up to 1 Watt (30 dBm) in the 2400-2483.5 MHz band. For spurious emmissions the limit is -20 dBc based on either conducted or radiated measurement, if the emission is not in a restricted band. The restricted bands are speci-fied in FCC 15.205. In these bands the spurious emission levels must meet the levels set out in FCC 15.209. In the range from 960 MHz to the frequency of the 5th harmonic it is defined as 0.5 mV/m at 3 m distance (equals to -41.2 dBm in EIRP).Additionally, for spurious frequencies above 1 GHz, FCC 15.35 allows duty-cycle relaxation to the regulatory limits. For the EmberZNet PRO the relaxation is 3.6 dB. Therefore, the -41.2 dBm limit can be modified to -37.6 dBm.If operating in the 2400-2483.5 MHz band the 2nd, 3rd and 5th harmonics can fall into restricted bands. As a result, for those the -37.6 dBm limit should be applied. For the 4th harmonic the -20 dBc limit should be applied.6.2.3 Applied Emission Limits for the 2.4 GHz BandThe above ETSI limits are applied both for conducted and radiated measurements.The FCC restricted band limits are radiated limits only. Besides that, Silicon Labs applies those to the conducted spectrum i.e., it is assumed that, in case of a custom board, an antenna is used which has 0 dB gain at the fundamental and the harmonic frequencies. In that theoretical case, based on the conducted measurement, the compliance with the radiated limits can be estimated.The overall applied limits are shown in the table below.Table 6.1. Applied Limits for Spurious Emissions for the 2.4 GHz Band | Smart. Connected. Energy-friendly.Rev. 1.7 | 87. RF Performance7.1 Conducted Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V.7.1.1 Conducted Measurements in the 2.4 GHz bandThe BRD4151A board was connected directly to a Spectrum Analyzer through its UFL connector (the R1 resistor (0 Ohm) was removed and a 0 Ohm resistor was soldered to the R2 resistor position). During measurements, the voltage supply for the board was 3.3 V provi-ded by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4151A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to the maximum level.The typical output spectrum is shown in the following figure.Figure 7.1. Typical Output Spectrum of the BRD4151AAs it can be observed, the fundamental is slightly lower than 19.5 dBm and the strongest unwanted emission is the double-frequency harmonic and it is under the -37.6 dBm applied limit.Note: The conducted measurement is performed by connecting the on-board UFL connector to a Spectrum Analyzer through an SMA Conversion Adapter (P/N: HRMJ-U.FLP(40)). This connection itself introduces approximately a 0.3 dB insertion loss.RF PerformanceRev. 1.7 | 97.2 Radiated Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V. The radiated power was measured in an antenna chamber by rotating the DUT 360degrees with horizontal and vertical reference antenna polarizations in the XY , XZ and YZ cuts. The measurement axes are shown inthe figure below.Figure 7.2. DUT: Radio Board with the Wireless Starter Kit Mainboard (Illustration)Note: The radiated measurement results presented in this document were recorded in an unlicensed antenna chamber. Also the radi-ated power levels may change depending on the actual application (PCB size, used antenna, and so on). Therefore, the absolute levels and margins of the final application are recommended to be verified in a licensed EMC testhouse.7.2.1 Radiated Measurements in the 2.4 GHz bandFor the transmitter antenna, the on-board printed Inverted-F antenna of the BRD4151A board was used (the R1 resistor (0 Ohm) was mounted). During the measurements the board was attached to a Wireless Starter Kit Mainboard (BRD4001 (Rev. A02) ) which was supplied through USB. During measurements, the voltage supply for the board was 3.3 V provided by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4151A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to the maximum level.The results are shown in the table below.Table 7.1. Maximums of the Measured Radiated Powers of BRD4151AAs it can be observed, thanks to the high gain of the Inverted-F antenna, the level of the fundamental is higher than 19.5 dBm. The strongest harmonic is the double-frequency one but its level is under -45 dBm.RF PerformanceEMC Compliance Recommendations 8. EMC Compliance Recommendations8.1 Recommendations for 2.4 GHz ETSI EN 300-328 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4151A EFR32 Mighty Gecko Radio Board complies with the 20 dBm limit of the ETSI EN 300-328 in case of the conducted measurement but due to the high antenna gain the radiated power is higher than the limit by 2 dB. In order to comply, the output power should be reduced (with different antennas, de-pending on the gain of the used antenna, the necessary reduction can be different). The harmonic emissions are under the -30 dBm limit. Although the BRD4151A Radio Board has an option for mounting a shielding can, that is not required for the compliance.8.2 Recommendations for 2.4 GHz FCC 15.247 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4151A EFR32 Mighty Gecko Radio Board complies with the 30 dBm limit of the FCC 15.247. The harmonic emissions are under the -37.6 dBm applied limit both in case of the conducted and the radiated measurements. Although the BRD4151A Radio Board has an option for mounting a shielding can, that is not required for the compliance.Board Revisions 9. Board RevisionsTable 9.1.

Silicon Labs电容触摸感应MCU的工作原理与基本特征

Silicon Labs电容触摸感应MCU的工作原理与基本特征现在的电子产品中，触摸感应技术日益受到更多关注和应用，并不断有新的技术和IC面世。

与此同时，高灵敏度的电容触摸技术也在快速地发展起来，其主要应用在电容触摸屏和电容触摸按键，但由于电容会受温度、湿度或接地情况的不同而变化，故稳定性较差，因而要求IC的抗噪性能要好，这样才能保证稳定正确的触摸感应。

针对市场的需求，来自美国的高效能模拟与混合信号IC创新厂商SILICON Laboratories(简称：SILICON Labs)公司特别推出了C8051F7XX和 C8051F8XX系列的MCU(单片机)，专门针对电容触摸感应而设计，在抗噪性能和运算速度上表现的非常突出。

一、 SILICON Labs公司的电容触摸系列MCU目前SILICON Labs公司推出的C8051F7xx和C8051F8xx等电容触摸系列MCU，以高信噪比高速度的特点在业界表现尤为出色。

同时，灵活的I/O配置，给设计带来更多的方便。

另外，由于该系列MCU内部集成了特殊的电容数字转换器(CDC)，所以能够进行高精度的电容数字转换实现电容触摸功能。

CDC的具体工作原理：，IREF是一个内部参考电流源，CREF是内部集成的充电电容，ISENSOR属于内部集成的受控电流源，CSENSOR为外部电容传感器的充电电容，由于人体的触摸引起CSENSOR的变化，通过内部调整过的ISENSOR对CSENSOR进行瞬间的充电，在CSENSOR上产生一个电压VSENSOR，然后相对内部参考电压经过一个共模差分放大器进行放大;同理IC内部的IREF对CREF充电后也产生一个参考电压并相对同样的VREF经过差分放大，最后将2个放大后的信号通过SAR(逐次逼近模数转换器)式的ADC采样算出ISENSOR的值。

图1SILICON Labs SAR式的ADC采样可选择12-16位的分辨率，，采用16位的分辨率进行逐位比较采样：首先从确定最高位第16位(IREF=0x8000)开始，最高位的值取决于电容的充电速率，也就相当于电流的大小，取电流IREF/2，比较VSENSOR和VREF：VSENSOR > VREF 则最高位 = 0 ;VSENSOR < VREF 则最高位 = 1 ;随后，SAR控制逻辑移至下一位，并将该位设置为高电平，进行下一次比较：如果第16位是1，则取下一个IREF=0xC000 ;如果第16位是0，则取下一个IREF=0x4000.这个过程一直持续到最低有效位(LSB)。

芯片公司Silicon Labs的应用说明书：EFR32系列1子GHz RF匹配的集成无动态设备

AN1081: Integrated Passive Devices for EFR32 Series 1 Sub-GHz RF MatchingThe external RF matching network for EFR32 Series 1 devices supporting sub-GHzband operation may be further simplified by integrating all components in a single, Inte-grated Passive Device (IPD). This application note covers the various aspects of utiliz-ing an IPD in an EFR32 Series 1 design.EFR32 Series 1 devices supporting sub-GHz frequency bands utilize an external matching network. This network serves several purposes, including impedance trans-formation from a 50 Ω antenna to the optimum transmit and receive path impedances for EFR32, single-ended to differential conversion, and lowpass filtering to minimize transmit harmonics and receive out-of-band interference. This network is often imple-mented by discrete components. Some applications, however, benefit in terms of mini-mized space, bill of materials, and complexity by integrating all in a single ceramic de-vice, the IPD.Readers interested in a detailed description of the discrete sub-GHz matching network should refer to AN923: EFR32 sub-GHz Matching Guide.Performance data for the individual EFR32 Series 1 IPDs are provided in the following application notes:•AN1146: Johanson 434 MHz IPDs for EFR32 Series 1 Wireless SOCs•AN1147: Murata 434 MHz IPDs for EFR32 Series 1 Wireless SOCs•AN1148: Johanson 868 MHz IPDs for EFR32 Series 1 Wireless SOCs•AN1149: Murata 868 MHz IPDs for EFR32 Series 1 Wireless SOCs KEY POINTS•Integrated Passive Devices (IPDs) simplify the EFR32 Series 1 sub-GHz RF matching network design, reducing complexity and PCB board space by 70%•IPDs are available from leading RF ceramics providers supporting commonsub-GHz bands•Including IPDs in EFR32 Series 1 designsis made straightforward with a few hardware and software design considerationsRev. 0.2Supported Devices and Bands 1. Supported Devices and BandsIPDs are available from leading RF ceramics providers for common bands. As with the discrete EFR32 Series 1 matching networks, IPDs are optimized for a specific frequency, target output power, and supply voltage. Available designs are listed in the following table.Table 1.1. IPD Devices for EFR32 Series 1Note: Measurements on sample boards showed that the 868 MHz Murata and Johanson IPDs can be used at 3.3 V VDDPA supply voltage: ~ 18-19 dBm output power can be achieved with acceptable TX current and harmonic performance. However, note that exten-sive characterization of the 868 MHz Murata and Johanson IPDs were performed only for max. +14 dBm transmit power when the PA is powered from 1.8 V. | Building a more connected world.Rev. 0.2 | 22. ImplementationIncorporation of an IPD in an EFR32 Series 1 design is straightforward with a few additional considerations in PCB and firmware de-signs.2.1 PCB DesignPCB design is straightforward with focus on minimizing trace lengths and parasitic reactances.Key considerations include:•Grounding of IPD ground pins: All should have a clear / straightforward return path to the main RF ground, typically on the PCB plane below the IPD and RFIC.•Antenna Connection: Provides a 50 Ω controlled impedance connection from IPD ANT port to antenna. This net should include a 56 pF ac coupling capacitor C COUPLE as some IPD designs' antenna ports are dc-coupled.•DC Bypass Capacitor, C BYPASS: 56 pFThe reference RF section schematic and layout and recommended PCB land pattern are shown in the figures below.Refer to AN928.1: EFR32 Series 1 Layout Design Guide for additional EFR32 Series 1 PCB design guidance.Figure 2.1.

Lighter colors denote recommended ground fill beneath the device. Pads 0.3 mm x 0.5 mm, 10 pla-ces.Rev. 0.2 | 42.2 Firmware/SoftwareAs with the discrete design, there are a few firmware configuration items to consider when using the IPD, including:•PA initialization: Includes VDDPA source, etc.•PA dBm curve optimization: The dBm-based API input refers back to a curvefit to determine the correct PA device settings. This curve is slightly different for each match and should be optimized. As well, the offset value may be different for different RF front ends.•PA tuning (sgpactune value): This is an internal tuning value, optimized for each matching network, supply voltage, and frequency.Optimal values have been determined by Silicon Labs and the IPD manufacturer and are listed in Table 1.1 IPD Devices for EFR32 Series 1 on page 2.Refer to the RAIL API programming literature for details on the API calls required to implement these items.Simplicity StudioOne-click access to MCU and wireless tools, documentation, software, source code libraries & more.

Silicon Labs ETRX2 和 ETRX357 无线网络模块互联互通指南说明书

Telegesis™ is a trademark of Silicon Laboratories Inc.ETRX2 and ETRX357 Wireless Mesh Networking Modules Application Note – Accessing Modules over the InternetTable of Contents1INTRODUCTION (3)2OBSTACLES (3)3CONFIGURING A GATEWAY (4)4COMMUNICATING WITH THE EAP (9)5OUTGOING CONNECTIONS FROM AN EAP (9)6WARNING (12)1 IntroductionThe serial port of the ETRX2 and ETRX357 modules can be connected to an Ethernet network via a suitable adaptor such as a Lantronix XPort Direct+, which is the basis of the EAP-E device. It is then simple to communicate with the module, either using a HyperTerminal connection directly to its IP address or by using the Lantronix COM Port Redirector to map the IP address to a virtual COM port.This is straightforward on a local sub-net, but it is less clear how to achieve this over longer range. This note describes the general principles of configuring a gateway such as a broadband router so that a local PC can connect to a remote EAP and open a TCP connection. Aspects such as firewall security and creating a web server are beyond the scope of this note, which just details the first steps in forming a simple connection from a PC to a remote EAP. It gives examples using a typical domestic gateway device (a Thomson ST546) but others will be similar.This application note was originally written with regard to the EAP-E Ethernet Access Point which is now obsolete, but the same principles apply to its replacement, the Communications Gateway.2 ObstaclesGateway devices use Network Address Translation (NAT) to hide the local network from public view. Local devices acquire an IP address from the gateway/router which are typically 192.168.x.x for a private network, but the gateway translates this to its own address assigned by the Internet Service Provider. In this way the gateway can provide a firewall which hides the local devices and only allows incoming packets in response to an outgoing request, and it allows multiple PCs to access the Internet while the ISP only has to provide a single IP address.The difficulty is then that an EAP gets an IP address from the gateway but a remote user has no way of connecting to it directly. A solution is to drill a hole in the gateway’s firewall by using port forwarding (or port mapping). In this way, packets addressed to a specific port or range of ports of the gateway are always routed to the EAP. A remote user then just needs the IP address of the gateway and the relevant port number.3 Configuring a gatewayFirst it is necessary to know the local IP address and port number of the EAP. The standard port number is 10001 for a Lantronix XPort Direct+. The EAP is usually configured to use DHCP and will acquire its IP address from the gateway/router, and it is important to ensure that this does not change. The address can often be obtained from the maintenance web pages of the router, which often allows you to fix the address. Otherwise the EAP can be configured to use static IP addressing; the Lantronix Device Installer tool is the easiest to use since it can discover the devices and report their IP address. It allows you to change the device settings via Telnet or a web browser, and the web page for the address settings look like this:2. EAP after port mapping 1. Network devices with example addresses3. EAP address settingsThe exact procedure for setting up port mapping on your gateway depends on the model, but it will usually start by accessing the maintenance pages from a web browser. For example, a particularThomson gateway displays a map of the local network:4. Local network mapIt has assigned the name CA8CADF to an EAP based on the MAC address of the Lantronix module. Clicking on that device icon brings up all the relevant information including its IP address. Port forwarding may be described in different ways such as “Port Mapping”, “Gaming” or “Application Sharing” but the end result is the same. There is likely to be a predefined set of mapping rules for various applications but it is simpler to add a new one. There will be typically three stages to this:1. Create a new rule and give it a name2. Define the mapping rule for the port or range of ports. Port 10001 is not used very much on the Internet so it should be safe to retain the same port number on the public and private sides of the gateway. On the Thomson example there is a form to define the port mapping (the map in thisinstance has already been defined; this is the page to edit it but it is essentially the same):5. Port mapping ruleAt this stage the mapping rule is not assigned to any particular device.3. Define the local device to which the rule applies. This will involve selecting it from a list ofdiscovered devices (figure 6) or by typing in the EAP’s IP address (figure 7):6. Assign rule to a discovered device7. Assign rule to an IP addressFinally, note the IP address that the gateway uses on its public side. This is unlikely to change over a few days, but you could use a dynamic DNS service to track the changes. Consult the manual of your gateway for more details.You should now be ready to access the EAP from the outside world.4 Communicating with the EAPTelegesis Terminal may be suitable as the latest version can access IP addresses. HyperTerminal works if you have it on your machine (for some reason Microsoft dropped it after Windows XP), otherwise use your favourite terminal application or a basic tool such as Telnet. In HyperTerminal, start by creating a new connection and enter the connection data:The host address is obviously the public IP address of your gateway. The connection should then open automatically and you can type in the commands appropriate to the ZigBee firmware – the AT command set of the R3xx firmware for example, or start receiving data from a device programmed to transmit automatically.5 Outgoing connections from an EAPThe Lantronix Direct+ module by default accepts any incoming request for a connection, but is otherwise idle. Instead, you can set it to open a connection when it starts up:8. Opening an automatic connectionThis connection can be a single address, listed here as “Remote host”:9. Ethernet connection settingsAlternatively you can create a hostlist and the EAP will connect to the first available address:10. HostlistConsult the latest user guide for the full details, which is currently downloadable from /support/downloads/?p=XPORTDIRECTPLS6 WarningPutting a hole in your gateway’s firewall has possibl e security implications which are outside the scope of this note. A malicious port scanner could exploit this hole, but it would only be able to access the EAP unit. There may be critical ZigBee systems where this is not acceptable, but thisnote is only an introduction to setting up a simple link.

System Overview3.1 IntroductionThe EFR32 product family combines an energy-friendly MCU with a high performance radio transceiver. The devices are well suited for secure connected IoT multiprotocol devices requiring high performance and low energy consumption. This section gives a short intro-duction to the full radio and MCU system. The detailed functional description can be found in the EFR32xG21 Reference Manual.A block diagram of the EFR32BG21B family is shown in Figure 3.1 Detailed EFR32BG21B Block Diagram on page 7. The diagram shows a superset of features available on the family, which vary by OPN. For more information about specific device features, consult Ordering Information .RESETnDVDDAVDD PAVDD RFVDD DECOUPLEIOVDD PDnPCnPBnPAnRF2G4_IO1RF2G4_IO2Figure 3.1. Detailed EFR32BG21B Block Diagram3.2 RadioThe EFR32BG21B features a highly configurable radio transceiver supporting the Bluetooth Low Energy wireless protocol.3.2.1 Antenna InterfaceThe 2.4 GHz antenna interface consists of two single-ended pins (RF2G4_IO1 and RF2G4_IO2) that interface directly to two LNAs and two 10 dBm PAs. For devices that support 20 dBm, these pins also interface to the 20 dBm on-chip balun. Integrated switches select either RF2G4_IO1 or RF2G4_IO2 to be the active path.The external components and power supply connections for the antenna interface typical applications are shown in the RF Matching Networks section.Rev. 1.0 | 73.2.2 Fractional-N Frequency SynthesizerThe EFR32BG21B contains a high performance, low phase noise, fully integrated fractional-N frequency synthesizer. The synthesizer is used in receive mode to generate the LO frequency for the down-conversion mixer. It is also used in transmit mode to directly gener-ate the modulated RF carrier.The fractional-N architecture provides excellent phase noise performance, frequency resolution better than 100 Hz, and low energy consumption. The synthesizer’s fast frequency settling allows for very short receiver and transmitter wake up times to reduce system energy consumption.3.2.3 Receiver ArchitectureThe EFR32BG21B uses a low-IF receiver architecture, consisting of a Low-Noise Amplifier (LNA) followed by an I/Q down-conversion mixer. The I/Q signals are further filtered and amplified before being sampled by the IF analog-to-digital converter (IFADC).The IF frequency is configurable from 150 kHz to 1371 kHz. The IF can further be configured for high-side or low-side injection, provid-ing flexibility with respect to known interferers at the image frequency.The Automatic Gain Control (AGC) module adjusts the receiver gain to optimize performance and avoid saturation for excellent selec-tivity and blocking performance. The 2.4 GHz radio is calibrated at production to improve image rejection performance.Demodulation is performed in the digital domain. The demodulator performs configurable decimation and channel filtering to allow re-ceive bandwidths ranging from 0.1 to 2530 kHz. High carrier frequency and baud rate offsets are tolerated by active estimation and compensation. Advanced features supporting high quality communication under adverse conditions include forward error correction by block and convolutional coding as well as Direct Sequence Spread Spectrum (DSSS).A Received Signal Strength Indicator (RSSI) is available for signal quality metrics, for level-based proximity detection, and for RF chan-nel access by Collision Avoidance (CA) or Listen Before Talk (LBT) algorithms. An RSSI capture value is associated with each received frame and the dynamic RSSI measurement can be monitored throughout reception.3.2.4 Transmitter ArchitectureThe EFR32BG21B uses a direct-conversion transmitter architecture. For constant envelope modulation formats, the modulator controls phase and frequency modulation in the frequency synthesizer. Transmit symbols or chips are optionally shaped by a digital shaping filter. The shaping filter is fully configurable, including the BT product, and can be used to implement Gaussian or Raised Cosine shap-ing.Carrier Sense Multiple Access - Collision Avoidance (CSMA-CA) or Listen Before Talk (LBT) algorithms can be automatically timed by the EFR32BG21B. These algorithms are typically defined by regulatory standards to improve inter-operability in a given bandwidth be-tween devices that otherwise lack synchronized RF channel access.3.2.5 Packet and State TraceThe EFR32BG21B Frame Controller has a packet and state trace unit that provides valuable information during the development phase. It features:•Non-intrusive trace of transmit data, receive data and state information•Data observability on a single-pin UART data output, or on a two-pin SPI data output•Configurable data output bitrate / baudrate•Multiplexed transmitted data, received data and state / meta information in a single serial data stream3.2.6 Data BufferingThe EFR32BG21B features an advanced Radio Buffer Controller (BUFC) capable of handling up to 4 buffers of adjustable size from 64 bytes to 4096 bytes. Each buffer can be used for RX, TX or both. The buffer data is located in RAM, enabling zero-copy operations.3.2.7 Radio Controller (RAC)The Radio Controller controls the top level state of the radio subsystem in the EFR32BG21B. It performs the following tasks:•Precisely-timed control of enabling and disabling of the receiver and transmitter circuitry•Run-time calibration of receiver, transmitter and frequency synthesizer•Detailed frame transmission timing, including optional LBT or CSMA-CA3.3 General Purpose Input/Output (GPIO)EFR32BG21B has up to 20 General Purpose Input/Output pins. Each GPIO pin can be individually configured as either an output or input. More advanced configurations including open-drain, open-source, and glitch-filtering can be configured for each individual GPIO pin. The GPIO pins can be overridden by peripheral connections, like SPI communication. Each peripheral connection can be routed to several GPIO pins on the device. The input value of a GPIO pin can be routed through the Peripheral Reflex System to other peripher-als. The GPIO subsystem supports asynchronous external pin interrupts.All of the pins on ports A and port B are EM2 capable. These pins may be used by Low-Energy peripherals in EM2/3 and may also be used as EM2/3 pin wake-ups. Pins on ports C and D are latched/retained in their current state when entering EM2 until EM2 exit upon which internal peripherals could once again drive those pads.A few GPIOs also have EM4 wake functionality. These pins are listed in .3.4 Clocking3.4.1 Clock Management Unit (CMU)The Clock Management Unit controls oscillators and clocks in the EFR32BG21B. Individual enabling and disabling of clocks to all pe-ripheral modules is performed by the CMU. The CMU also controls enabling and configuration of the oscillators. A high degree of flexi-bility allows software to optimize energy consumption in any specific application by minimizing power dissipation in unused peripherals and oscillators.3.4.2 Internal and External OscillatorsThe EFR32BG21B supports two crystal oscillators and fully integrates five RC oscillators, listed below.• A high frequency crystal oscillator (HFXO) with integrated load capacitors, tunable in small steps, provides a precise timing refer-ence for the MCU and RF synthesizer. The HFXO provides excellent RF clocking performance using a 38.4 MHz crystal. The HFXO can also support an external clock source such as a TCXO for applications that require an extremely accurate clock frequency over temperature.• A 32.768 kHz crystal oscillator (LFXO) provides an accurate timing reference for low energy modes.•An integrated high frequency RC oscillator (HFRCO) is available for the MCU system, when crystal accuracy is not required. The HFRCO employs fast start-up at minimal energy consumption combined with a wide frequency range, from 1 MHz to 80 MHz.•An integrated high frequency RC oscillator (HFRCOEM2) runs down to EM2 and is available for timing the general-purpose ADC and the Serial Wire Viewer port with a wide frequency range.•An integrated fast start-up RC oscillator (FSRCO) that runs at a fixed 20 MHz•An integrated low frequency 32.768 kHz RC oscillator (LFRCO) for low power operation where high accuracy is not required.•An integrated ultra-low frequency 1 kHz RC oscillator (ULFRCO) is available to provide a timing reference at the lowest energy con-sumption in low energy modes.3.5 Counters/Timers and PWM3.5.1 Timer/Counter (TIMER)TIMER peripherals keep track of timing, count events, generate PWM outputs and trigger timed actions in other peripherals through the Peripheral Reflex System (PRS). The core of each TIMER is a 16-bit or 32-bit counter with up to 3 compare/capture channels. Each channel is configurable in one of three modes. In capture mode, the counter state is stored in a buffer at a selected input event. In compare mode, the channel output reflects the comparison of the counter to a programmed threshold value. In PWM mode, the TIMER supports generation of pulse-width modulation (PWM) outputs of arbitrary waveforms defined by the sequence of values written to the compare registers. In addition some timers offer dead-time insertion.See 3.12 Configuration Summary for information on the feature set of each timer.3.5.2 Low Energy Timer (LETIMER)The unique LETIMER is a 24-bit timer that is available in energy mode EM0 Active, EM1 Sleep, EM2 Deep Sleep, and EM3 Stop. This allows it to be used for timing and output generation when most of the device is powered down, allowing simple tasks to be performed while the power consumption of the system is kept at an absolute minimum. The LETIMER can be used to output a variety of wave-forms with minimal software intervention. The LETIMER is connected to the Peripheral Reflex System (PRS), and can be configured to start counting on compare matches from other peripherals such as the Real Time Clock.3.5.3 Real Time Clock with Capture (RTCC)The Real Time Clock with Capture (RTCC) is a 32-bit counter providing timekeeping down to EM3. The RTCC can be clocked by any of the on-board low-frequency oscillators, and it is capable of providing system wake-up at user defined intervals.A secondary RTC is used by the RF protocol stack for event scheduling, leaving the primary RTCC block available exclusively for appli-cation software.3.5.4 Back-Up Real Time Counter (BURTC)The Back-Up Real Time Counter (BURTC) is a 32-bit counter providing timekeeping in all energy modes, including EM4. The BURTC can be clocked by any of the on-board low-frequency oscillators, and it is capable of providing system wake-up at user defined inver-vals.3.5.5 Watchdog Timer (WDOG)The watchdog timer can act both as an independent watchdog or as a watchdog synchronous with the CPU clock. It has windowed monitoring capabilities, and can generate a reset or different interrupts depending on the failure mode of the system. The watchdog can also monitor autonomous systems driven by the Peripheral Reflex System (PRS).3.6 Communications and Other Digital Peripherals3.6.1 Universal Synchronous/Asynchronous Receiver/Transmitter (USART)The Universal Synchronous/Asynchronous Receiver/Transmitter is a flexible serial I/O module. It supports full duplex asynchronous UART communication with hardware flow control as well as RS-485, SPI, MicroWire and 3-wire. It can also interface with devices sup-porting:•ISO7816 SmartCards•IrDA•I2S3.6.2 Inter-Integrated Circuit Interface (I2C)The I2C module provides an interface between the MCU and a serial I2C bus. It is capable of acting as both a master and a slave and supports multi-master buses. Standard-mode, fast-mode and fast-mode plus speeds are supported, allowing transmission rates from 10 kbit/s up to 1 Mbit/s. Slave arbitration and timeouts are also available, allowing implementation of an SMBus-compliant system. The interface provided to software by the I2C module allows precise timing control of the transmission process and highly automated trans-fers. Automatic recognition of slave addresses is provided in active and low energy modes. Note that not all instances of I2C are avalia-ble in all energy modes.3.6.3 Peripheral Reflex System (PRS)The Peripheral Reflex System provides a communication network between different peripheral modules without software involvement. Peripheral modules producing Reflex signals are called producers. The PRS routes Reflex signals from producers to consumer periph-erals which in turn perform actions in response. Edge triggers and other functionality such as simple logic operations (AND, OR, NOT) can be applied by the PRS to the signals. The PRS allows peripherals to act autonomously without waking the MCU core, saving pow-er.3.7 Secure Vault High FeaturesA dedicated Hardware Secure Engine containing its own CPU enables the Secure Vault High functions. It isolates cryptographic func-tions and data from the host Cortex-M33 core and provides the following security features:•Secure Boot with Root of Trust and Secure Loader (RTSL)•Cryptographic Accelerator•True Random Number Generator (TRNG)•Secure Debug with Lock/Unlock•DPA Countermeasures•Secure Key Management with PUF•Anti-Tamper•Secure Attestation3.7.1 Secure Boot with Root of Trust and Secure Loader (RTSL)The Secure Boot with RTSL authenticates a chain of trusted firmware that begins from an immutable memory (ROM).It prevents malware injection, prevents rollback, ensures that only authentic firmware is executed and protects Over The Air updates. More information on this feature can be found in the Application Note AN1218: Series 2 Secure Boot with RTSL.3.7.2 Cryptographic AcceleratorThe Cryptographic Accelerator is an autonomous hardware accelerator with Differential Power Analysis (DPA) countermeasures to pro-tect keys.It supports AES encryption and decryption with 128/192/256-bit keys, ChaCha20 encryption, and Elliptic Curve Cryptography (ECC) to support public key operations and hashes.Supported block cipher modes of operation for AES include:•ECB (Electronic Code Book)•CTR (Counter Mode)•CBC (Cipher Block Chaining)•CFB (Cipher Feedback)•GCM (Galois Counter Mode)•CCM (Counter with CBC-MAC)•CBC-MAC (Cipher Block Chaining Message Authentication Code)•GMAC (Galois Message Authentication Code)The Cryptographic Accelerator accelerates Elliptical Curve Cryptography and supports the NIST (National Institute of Standards and Technology) recommended curves including P-192, P-256, P-384, and P-521 for ECDH (Elliptic Curve Diffie-Hellman) key derivation and ECDSA (Elliptic Curve Digital Signature Algorithm) sign and verify operations. Also supported is the non-NIST Curve25519 for ECDH and Ed25519 for EdDSA (Edwards-curve Digital Signature Algorithm) sign and verify operations.Secure Vault also supports ECJ-PAKE (Elliptic Curve variant of Password Authenticated Key Exchange by Juggling) and PBKDF2 (Password-Based Key Derivation Function 2).Supported hashes include SHA-1, SHA-2/256/384/512 and Poly1305.This implementation provides a fast and energy efficient solution to state of the art cryptographic needs.3.7.3 True Random Number GeneratorThe True Random Number Generator module is a non-deterministic random number generator that harvests entropy from a thermal energy source. It includes start-up health tests for the entropy source as required by NIST SP800-90B and AIS-31 as well as online health tests required for NIST SP800-90C.The TRNG is suitable for periodically generating entropy to seed an approved pseudo random number generator.3.7.4 Secure Debug with Lock/UnlockFor obvious security reasons, it is critical for a product to have its debug interface locked before being released in the field.In addition, Secure Vault High also provides a secure debug unlock function that allows authenticated access based on public key cryp-tography. This functionality is particularly useful for supporting failure analysis while maintaining confidentiality of IP and sensitive end-user data.More information on this feature can be found in the Application Note AN1190: Series 2 Secure Debug.3.7.5 DPA CountermeasuresThe AES and ECC accelerators have Differential Power Analysis (DPA) countermeasures support. This makes it very expensive from a time and effort standpoint to use DPA to recover secret keys.3.7.6 Secure Key Management with PUFKey material in Secure Vault High products is protected by what is called "key wrapping" with a standardized symmetric encryption mechanism. This method has the advantage of being able to protect a virtually unlimited number of keys, limited only by the storage that is accessible by the Cortex-M33 (which includes off-chip storage as well). The symmetric key used for this wrapping and unwrap-ping must be highly secure as it can expose all other key material in the system. The Secure Vault Key Management system uses a Physically Unclonable Function (PUF) to generate a persistent device-unique seed key on power up to dynamically generate this critical wrapping/unwrapping key which is only visible to the AES encryption engine and is not retained when the device loses power.3.7.7 Anti-TamperSecure Vault High devices provide internal tampers monitoring the system such as voltage, temperature, and electro-mechanical pul-ses as well as detecting tamper of the security sub-system itself. There are also 8 external configurable tamper pins for supporting ex-ternal tamper sources like case tamper switches.For each tamper event, the user is able to select the severity of the tamper response ranging from an interrupt, to a reset, to destroying the PUF reconstruction data which will make all the protected key material un-recoverable and effectively render the device inoperable. The tamper system also has an internal resettable event counter with programmable trigger threshold and refresh periods to mitigate false positive tamper events.More information on this feature can be found in the Application Note AN1247: Anti-Tamper Protection Configuration and Use.3.7.8 Secure AttestationSecure Vault High products support Secure Attestation, which begins with a secure identity that is created during the Silicon Labs man-ufacturing process. During device production, each device generates its own public/private keypair and securely stores the wrapped private key into immutable OTP memory, and this key never leaves the device. The corresponding public key is extracted from the de-vice and inserted into a binary DER-encoded X.509 device certificate which is signed into a Silicon Labs CA chain and then program-med back into the chip into an immutable OTP memory.This secure identity can be used to authenticate the chip at any time in the life of the product. The production certification chain can be requested remotely from the product. This certification chain can be used to verify that the device was authentically produced by Silicon Labs. The device unique public key is also bound to the device certificate in the certification chain. A challenge can be sent to the chip at any point in time to be signed by the device private key. The public key in the device certificate can then be used to verify the chal-lenge response, proving that the device has access to the securely-stored private key, which prevents counterfeit products or imperso-nation attacks.More information on this feature can be found in the Application Note AN1268: Authenticating Silicon Labs Devices Using Device Certif-icates.3.8 Analog3.8.1 Analog Comparator (ACMP)The Analog Comparator is used to compare the voltage of two analog inputs, with a digital output indicating which input voltage is high-er. Inputs are selected from among internal references and external pins. The tradeoff between response time and current consumption is configurable by software. Two 6-bit reference dividers allow for a wide range of internally-programmable reference sources. The ACMP can also be used to monitor the supply voltage. An interrupt can be generated when the supply falls below or rises above the programmable threshold.3.8.2 Analog to Digital Converter (IADC)The IADC is a hybrid architecture combining techniques from both SAR and Delta-Sigma style converters. It has a resolution of up to 12 bits at up to 1 Msps. Hardware oversampling reduces system-level noise over multiple front-end samples. The IADC includes integrated voltage references. Inputs are selectable from a wide range of sources, including pins configurable as either single-ended or differential.3.9 Reset Management Unit (RMU)The RMU is responsible for handling reset of the EFR32BG21B. A wide range of reset sources are available, including several power supply monitors, pin reset, software controlled reset, core lockup reset, and watchdog reset.3.10 Core and Memory3.10.1 Processor CoreThe ARM Cortex-M processor includes a 32-bit RISC processor integrating the following features and tasks in the system:•ARM Cortex-M33 RISC processor achieving 1.50 Dhrystone MIPS/MHz•ARM TrustZone security technology•Embedded Trace Macrocell (ETM) for real-time trace and debug•Up to 1024 kB flash program memory•Up to 96 kB RAM data memory•Configuration and event handling of all modules•2-pin Serial-Wire debug interface3.10.2 Memory System Controller (MSC)The Memory System Controller (MSC) is the program memory unit of the microcontroller. The flash memory is readable and writable from both the Cortex-M and DMA. In addition to the main flash array where Program code is normally written the MSC also provides an Information block where additional information such as special user information or flash-lock bits are stored. There is also a read-only page in the information block containing system and device calibration data. Read and write operations are supported in energy modes EM0 Active and EM1 Sleep.3.10.3 Linked Direct Memory Access Controller (LDMA)The Linked Direct Memory Access (LDMA) controller allows the system to perform memory operations independently of software. This reduces both energy consumption and software workload. The LDMA allows operations to be linked together and staged, enabling so-phisticated operations to be implemented.。

The component values were optimized for the 915 MHz band RF performace and current consumption with 20 dBm output power.For more details on the matching network used on the BRD4503B (Rev. A00) see Chapter 4.1 Matching network3.7 SMA connectorTo be able to perform conducted measurements or mount external antenna for radiated measurements, range tests etc., Silicon Labs added an SMA connector (P/N: 5-1814832-1) to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.3.8 Radio Board ConnectorsTwo dual-row, 0.05” pitch polarized connectors (P/N: SFC-120-T2-L-D-A-K-TR) make up the EZR32WG Radio Board interface to the Wireless Starter Kit Mainboard.For more information on the pin mapping between the EZR32WG330F256R63G and the Radio Board Connector refer to Chapter 1. Radio Board Connector Pin Associations.4. RF sectionThe BRD4503B (Rev. A00) Radio Board includes a Class E type TX matching network with the targeted output power of 20 dBm at 915 MHz.The main advantage of the Class E matching types is their very high efficiency. They are proposed for applications where the current consumption is most critical, e.g., the typical total EZRadioPRO chip current with Class E type matching is ~75-90 mA at ~20 dBm power levels (using the 20 dBm PA output and assuming 3.3 V Vdd).The main disadvantage of the Class E type matches is the high Vdd dependency (the power variation is proportional to the square of the Vdd change: i.e. the decrease in power can be ~6 dB in the 1.8–3.8 V range) and the inaccurate nonlinear power steps. Also their current consumption and the peak voltage on the TX pin are sensitive to the termination impedance variation, and they usually require slightly higher order filtering and thus higher bill of materials cost.The matching network is constructed with a so-called Switched RF configuration where the TX and RX sides are connected together with an additional RF switch, to be able to use one antenna both for transmitting and receiveing. Careful design procedure was followed to ensure that the RX input circuitry does not load down the TX output path while in TX mode and that the TX output circuitry does not degrade receive performance while in RX mode.For detailed explanation of the Class E type TX matching and the Switched RF configuration matching procedure the reader is referred to "AN648: Si4063/Si4463/64/68 TX Matching". For detailed description of the RX matching the reader is referred to "AN643: Si446x/ Si4362 RX LNA Matching".4.1 Matching networkThe matching network structure used on the BRD4503B (Rev. A00) Radio Board is shown in the figure below.Filter1Figure 4.1. RF section of the schematic of the EZR32 Wonder Gecko Radio Board (BRD4503B (Rev. A00))The matching network has a so-called Switched RF configuration where the TX and RX sides are connected together, without an addi-tional RF switch, to be able to use one antenna both for transmitting and receiving.For detailed explanation of the TX matching process, see "AN648: Si4063/Si4463/64/68 TX Matching". Due to the Switched RF config-uration of the matching, the RX matching should also taken into account during the TX matching procedure. The above Application Note contains component values and a shorter description for the RX matching as well. For detailed description of the RX matching refer to "AN643: Si446x/Si4362 RX LNA Matching".The component values were optimized for the 915 MHz band RF performace and current consumption with 20 dBm output power. The resulting component values with part numbers are listed in the table below.Rev. 1.10 | 6Table 4.1. Bill of Materials for the BRD4503B (Rev. A00) RF matching networkThe Application Note "AN648: Si4063/Si4463/64/68 TX Matching" contains component values for reference matching networks which were developed for the EZRadioPRO Pico Boards. For the WSTK radio boards some fine-tuning of the component values may be nec-essary due to different parasitic effects (bonding wire, layout etc.). For optimized RF performance the component values listed in the table above may differ from the ones listed in the referred Application Note.For the reader’s specific application and board layout the adjustment of the final matching values might be necessary. The above com-ponent values should be used as starting points and the values modified slightly to zero-in on the best filter response and impedance match to 50 ohm. To minimize the differences due to different layout parasitics Silicon Labs recommends copying the layout of the RF section of the radio board as is. If that is not possible, refer to "AN629: Si4460/61/63/64 RF ICs Layout Design Guide" for layout design recommendations. | Smart. Connected. Energy-friendly.Rev. 1.10 | 75.

A00))was attached to a Wireless Starter Kit Mainboard (BRD4001 (Rev. A02)) and its transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 20 dBm (DDAC = 7Fh).6.2 Conducted Power MeasurementsIn case of the conducted measurements the output power was measured by connecting the EZR32WG Radio Board directly to a Spec-trum Analyzer (P/N: MS2692A) through its on-board SMA connector. At 20 dBm output power and 3.3 V supply voltage the measured typical current consumption of the RF section of the board is 90 mA.A typical output spectrum up to 10 GHz is shown in the figure below.Figure 6.1. Typical output spectrum of the BRD4503B (Rev. A00) Radio Board; with DDAC=7Fh at Vdd=3.3 VNote: In practice comercially available whip antennas usually have ~0-2 dB gain at the fundamental and < 0 dB gain at the harmonic frequencies so if the conducted levels are compliant with the emission limits with small margin it is likely that the margin on the harmon-ics radiated by an external whip antenna will be higher. Unfortunately in most cases, the PCB radiation (from traces or and/or compo-nents) is stronger so using shielding, applying larger duty cycle correction (if allowed) or reductionof the fundamental power could be necessary.6.3 Radiated Power MeasurementsFor radiated measurements an external whip antenna (P/N: W1063 (Pulse)) was used. The power supply for the board were two AA batteries (3 V). The batteries were connected to the Wireless Starter Kit Mainboard through its External Power Supply connector with minimal wire length to minimize the wire radiation.The DUT was rotated in 360 degree with horizontal and vertical reference antenna polarizations in the XY, XZ and YZ cuts. The meas-urement axes are as shown in the figure below.Figure 6.2. DUT: BRD4503B (Rev. A00) Radio Board with Wireless Starter Kit MainboardThe measured radiated powers are shown in the table below.Table 6.1. Results of the radiated power measurements with mounted shielding canOne may notice that the radiated harmonic levels are higher compared to the levels expected based on the conducted measurement. Investigations showed that this increase is due to the PCB radiations (components and PCB traces).Note: The radiated measurement results presented in this document were recorded in an unlicensed antenna chamber. Also the radi-ated power levels may change depending on the actual application (PCB size, used antenna etc.) therefore the absolute levels and margins of the final application is recommended to be verified in a licensed EMC testhouse!Document Revision History 7.

The SDK includes two separate ethernet examples, "eth" and"eth_device". The first example, "eth", demonstrates how the WF121 can be configured to operate as an Ethernet-to-WiFi bridge. The second example, "eth_device", demonstrates how the WF121 can be configured to operate as an Ethernet Device. This application note breaks down each of the two examples into their respective components so that each component can be described in a functional sense individually.Each of the two projects includes 2 BGScript source files, an HTML source file and companion CSS style sheet, a project configuration file, and an image used by the HTML source file. The BGScript source in each project are responsible for the application logic while the HTML source files provide a user facing medium (Web Page) for user defined parameters. This application note is comprised of three sections: the first sections provides an overview of the possible Ethernet connectivity modes, the second covers the "eth" example, and the last section covers the "eth_device" example.1.2 Ethernet connect modesThe WF121 is capable of operating in the one of the three following Ethernet "modes":Ethernet-to-Wi-Fi bridgeEthernet ServerEthernet Device1.2.1 BridgeBridge modeThe Ethernet-to-Wi-Fi Bridge mode can be used to provide Wi-Fi connectivity for devices that only support Ethernet connectivity. The "Bridge" forms a transparent data pipe between the Client ethernet interface and the Wi-Fi network connected to by the WF121, allowing for a bi-directional data stream.In this example, the setup is made easy by running an HTTP-server on the module, accessible via the Ethernet connection and a web browser. After the Wi-Fi network has been configured the WF121 will act as a Bridge and the Wi-Fi router only sees the end device (i.e., the device connected to WF121 over Ethernet) and will assign an IP address for the end device.1.2.2 Ethernet ServerEthernet ServerThe Ethernet server mode is designed to enable the configuration of the WF121 Wi-Fi module using internal web pages of the module. Using this setup the module may be setup to act as a Wi-Fi client in bridge mode. Before setting the mode on, the module must first be initialized like a Wi-Fi access point with or without DHCP server usage.1.2.3 Ethernet DeviceEthernet DeviceThe Ethernet device mode can be used to connect the WF121 to a network with an Ethernet cable.2 Implementing Wi-Fi Bridge ("eth" SDK example)The "eth" example included in the SDK demonstrates how the WF121 module may be configured to act as an Ethernet-to-Wi-Fi bridge between a Wi-Fi network and client device that only supports Ethernet connectivity. This section provides an overview of the "eth" example, breaking down the project into its' individual components.2.1 Project Configuration 2.2 Module firmware compiling and installation is covered in WF121 Configuration Guide.The project configuration is contained within the project.xml file. The project configuration for the "eth" example is defined by four tags: <hardware>,<script>, <binary>, and <files>.<hardware> Defines the XML-file or XML-tags containing the hardware configuration.<script> Defines the BGScript-file which contains the BGScript application code.<binary> Defines the WF121 firmware image used in the project.<files> Defines the HTML, CSS and image files used by the embedded HTTP server.2.2.1 Hardware ConfigurationThe project.xml file contains the hardware configuration for the WF121 Wi-Fi module. It describes which interfaces and functions are used and defines their properties:<uart> This setting configures the UART interface. The UART tag sets the UART2Interface to use 5000000 bps baud rate and enables hardware flow control. The UART provides access to the BGAPI protocol.<ethernet> This setting enables the Ethernet (RMII) interface on the WF121 module.<sleep> This setting enables INT0 (pin 38) wake-up interrupt.2.2.2 WF121 Development Kit Physical Hardware ConfigurationThe following switch positions should be used in regards to the WF121 Development KitSet the Ethernet switch (labeled SW1) to ON positionSet the UART1 switch (labeled SW4) to OFF positionSet the UART2 switch(labeled SW5) to ON positionSet board power switch (labeled SW14) to ON position2.3 BGScriptThe BGScript source file, wifi.bgs, included with the "eth" example is responsible for implementing the application logic. The BGScript source file, wifi.bgs, includes multiples events and procedures, which together, comprise the BGScript application functionality. The events most closely related to the overall application functionality are covered here in more detail.Functionality of embedded HTTP server is specified in HTTP Server Example v1.3 document.Flowchart illustrates the logical flow for a successful operation of the Ethernet-to-Wi-Fi Bridge.2.3.1 system_boot EventThe system_boot event when the module is powered up:The sme_wifi_is_on event is received when Wi-Fi hardware is initialized:The sme_scanned event is received when Wi-Fi access point scanning is done:2.3.4 sme_ap_mode_started EventThe sme_ap_mode_started event is recieved when Wi-Fi access point is initialized:The sme_connected event is received when module connection to defined Wi-Fi access point is ready:3 Implementing Ethernet device ("eth_device" SDK example)The goal of this example is to connect to a network via Ethernet cable or via Wi-Fi network. Wired network is the primary connection and the Wi-Fi connections acts as a backup. Before an automatic connection switch is possible, Wi-Fi access point information must be set by using the embedded HTTP server.3.1 Creating a projectThe process of creating a project and configuring the hardware is similar as in the Bridge mode example. 3.2 BgScript codeFlow chart illustrates the logical flow for linking the WF121 Ethernet device to a network with the Wi-Fi used as the backup connection.Functionality of the embedded HTTP server is specified in document HTTP Server Example v1.3 document.Ethernet Device flow3.2.1 Catching System bootSystem boot event is sent when the module is powered up:Silicon LabsPage 11 of 143.2.2 Catching Ethernet link status changeEthernet link status event is sent when the link is changed from up to down or vice versa:3.2.3 Catching Wi-Fi disconnected and Wi-Fi offDisconnected event is sent when the Wi-Fi connection is lost:Wi-Fi is off event is sent when the Wi-Fi state is changed from initialized to uninitialized:#***Nj.,-Fi is off***vent s me_wifi_is_off (s tate)c all ha rdwa re_i o_port_wr ite (LE D_P O R T,S T A_LE D,0)c all ether net_set_dataroute (E T H_D E VI CE)ndSilicon Labs Page 13 of 14 Silicon Laboratories Inc.400 West Cesar ChavezAustin, TX 78701USASimplicity StudioOne-click access to MCU andwireless tools, documentation,software, source code libraries &more.
