基于EFM8 8位MCU的智能家居系统开关设计
基于EFM8 8位MCU的智能家居系统开关设计随着现在越来越多的智能家居产品走进人们生活中，在智能家居的组网中，出现很多种通讯方式，为以前传统住房家用开关布线模式与现在智能产品的结合使用，保证用户需求的兼容性。
针对现代人生活习惯而设计了一款适配家居用的无线便捷墙壁开关。
说到开关人们就会想到墙壁开关控制灯，电动窗帘，电器插座这种老式开关不用考虑功耗，但家电类的产品就能想到遥控，当然遥控开关就是电池供电，所以产品功耗要求就比较严格，因此在设计时需要选择工作功耗低且外围电路可控的芯片。
尤其是遥控需要长期休眠的特性，因此就是要求芯片在待机状态下功耗低，外围电路可控就是除了必要的唤醒源外，其余外设都可以关闭，且唤醒方便。
除此之外，为了适配智能家居的产品，需要采用触摸按键，通过无线网络发送协议码（433MHz），同时在掉电后仍能够保存其数据的功能。
Silicon Labs EFM8SB1系列单片机控制芯片是一款基于最节能的8位MCU，非常适用于对功耗要求高的系统中，其120uA/MHz 运行功耗，0.5uA 睡眠电流,可以极大延长电池的使用寿命。

QFN24超小封装（4mm*4mm），高性价比。
此外，其也集成了最佳的电容式感应控制器，提供超低功耗，空闲模式，挂起模式，睡眠模式)。
Silicon Labs 红外接近传感器SI1153，检测范围0~50cm，或1~2m（加透镜），检测范围宽，可满足墙面开关对不同人体检测距离的要求；驱动红外LED 脉宽仅25.6 μs，可使系统平均功耗低，减轻墙面开关电源系统负担。
Sub -G无线通讯芯片（Si4438），最高发射功率达20dBm、接收灵敏度为-124dBm，非常适合应用在无线遥控家居使用环境，如穿墙等。
针对智能家居无线便捷墙壁开关系统的设计来说，单片机是设计的中心模块。

Detailed EFM8SB2 Block Diagram3.2 PowerAll internal circuitry draws power from the VDD supply pin. External I/O pins are powered from the VIO supply voltage (or VDD on devi-ces without a separate VIO connection), while most of the internal circuitry is supplied by an on-chip LDO regulator. Control over the device power can be achieved by enabling/disabling individual peripherals as needed. Each analog peripheral can be disabled when not in use and placed in low power mode. Digital peripherals, such as timers and serial buses, have their clocks gated off and draw little power when they are not in use.Table 3.1. Power Modes3.3 I/ODigital and analog resources are externally available on the device’s multi-purpose I/O pins. Port pins P0.0-P2.6 can be defined as gen-eral-purpose I/O (GPIO), assigned to one of the internal digital resources through the crossbar or dedicated channels, or assigned to an analog function. Port pin P2.7 can be used as GPIO. Additionally, the C2 Interface Data signal (C2D) is shared with P2.7.•Up to 24 multi-functions I/O pins, supporting digital and analog functions.•Flexible priority crossbar decoder for digital peripheral assignment.•Two drive strength settings for each pin.•Two direct-pin interrupt sources with dedicated interrupt vectors (INT0 and INT1).•Up to 16 direct-pin interrupt sources with shared interrupt vector (Port Match).3.4 ClockingThe CPU core and peripheral subsystem may be clocked by both internal and external oscillator resources. By default, the system clock comes up running from the 20 MHz low power oscillator divided by 8.•Provides clock to core and peripherals.•20 MHz low power oscillator (LPOSC0), accurate to +/- 10% over supply and temperature corners.•24.5 MHz internal oscillator (HFOSC0), accurate to +/- 2% over supply and temperature corners.•External RTC 32 kHz crystal.•External RC, C, CMOS, and high-frequency crystal clock options (EXTCLK).•Clock divider with eight settings for flexible clock scaling: Divide the selected clock source by 1, 2, 4, 8, 16, 32, 64, or 128.3.5 Counters/Timers and PWMReal Time Clock (RTC0)The RTC is an ultra low power, 36 hour 32-bit independent time-keeping Real Time Clock with alarm. The RTC has a dedicated 32 kHz oscillator. No external resistor or loading capacitors are required, and a missing clock detector features alerts the system if the external crystal fails. The on-chip loading capacitors are programmable to 16 discrete levels allowing compatibility with a wide range of crystals. The RTC module includes the following features:•Up to 36 hours (32-bit) of independent time keeping.•Support for external 32 kHz crystal or internal self-oscillate mode.•Internal crystal loading capacitors with 16 levels.•Operation in the lowest power mode and across the full supported voltage range.•Alarm and oscillator failure events to wake from the lowest power mode or reset the device.Programmable Counter Array (PCA0)The programmable counter array (PCA) provides multiple channels of enhanced timer and PWM functionality while requiring less CPU intervention than standard counter/timers. The PCA consists of a dedicated 16-bit counter/timer and one 16-bit capture/compare mod-ule for each channel. The counter/timer is driven by a programmable timebase that has flexible external and internal clocking options. Each capture/compare module may be configured to operate independently in one of five modes: Edge-Triggered Capture, Software Timer, High-Speed Output, Frequency Output, or Pulse-Width Modulated (PWM) Output. Each capture/compare module has its own associated I/O line (CEXn) which is routed through the crossbar to port I/O when enabled.•16-bit time base.•Programmable clock divisor and clock source selection.•Up to six independently-configurable channels•8, 9, 10, 11 and 16-bit PWM modes (edge-aligned operation).•Frequency output mode.•Capture on rising, falling or any edge.•Compare function for arbitrary waveform generation.•Software timer (internal compare) mode.•Integrated watchdog timer.Timers (Timer 0, Timer 1, Timer 2, and Timer 3)Several counter/timers are included in the device: two are 16-bit counter/timers compatible with those found in the standard 8051, and the rest are 16-bit auto-reload timers for timing peripherals or for general purpose use. These timers can be used to measure time inter-vals, count external events and generate periodic interrupt requests. Timer 0 and Timer 1 are nearly identical and have four primary modes of operation. The other timers offer both 16-bit and split 8-bit timer functionality with auto-reload and capture capabilities.Timer 0 and Timer 1 include the following features:•Standard 8051 timers, supporting backwards-compatibility with firmware and hardware.•Clock sources include SYSCLK, SYSCLK divided by 12, 4, or 48, the External Clock divided by 8, or an external pin.•8-bit auto-reload counter/timer mode•13-bit counter/timer mode•16-bit counter/timer mode•Dual 8-bit counter/timer mode (Timer 0)Timer 2 and Timer 3 are 16-bit timers including the following features:•Clock sources include SYSCLK, SYSCLK divided by 12, or the External Clock divided by 8.•16-bit auto-reload timer mode•Dual 8-bit auto-reload timer mode•Comparator 0 or RTC0 capture (Timer 2)•Comparator 1 or EXTCLK/8 capture (Timer 3)Watchdog Timer (WDT0)The device includes a programmable watchdog timer (WDT) integrated within the PCA0 peripheral. A WDT overflow forces the MCU into the reset state. To prevent the reset, the WDT must be restarted by application software before overflow. If the system experiences a software or hardware malfunction preventing the software from restarting the WDT, the WDT overflows and causes a reset. Following a reset, the WDT is automatically enabled and running with the default maximum time interval. If needed, the WDT can be disabled by system software. The state of the RSTb pin is unaffected by this reset.The Watchdog Timer integrated in the PCA0 peripheral has the following features:•Programmable timeout interval•Runs from the selected PCA clock source•Automatically enabled after any system reset3.6 Communications and Other Digital PeripheralsUniversal Asynchronous Receiver/Transmitter (UART0)UART0 is an asynchronous, full duplex serial port offering modes 1 and 3 of the standard 8051 UART. Enhanced baud rate support allows a wide range of clock sources to generate standard baud rates. Received data buffering allows UART0 to start reception of a second incoming data byte before software has finished reading the previous data byte.The UART module provides the following features:•Asynchronous transmissions and receptions•Baud rates up to SYSCLK/2 (transmit) or SYSCLK/8 (receive)•8- or 9-bit data•Automatic start and stop generationSerial Peripheral Interface (SPI0 and SPI1)The serial peripheral interface (SPI) module provides access to a flexible, full-duplex synchronous serial bus. The SPI can operate as a master or slave device in both 3-wire or 4-wire modes, and supports multiple masters and slaves on a single SPI bus. The slave-select (NSS) signal can be configured as an input to select the SPI in slave mode, or to disable master mode operation in a multi-master environment, avoiding contention on the SPI bus when more than one master attempts simultaneous data transfers. NSS can also be configured as a firmware-controlled chip-select output in master mode, or disabled to reduce the number of pins required. Additional general purpose port I/O pins can be used to select multiple slave devices in master mode.The SPI module includes the following features:•Supports 3- or 4-wire operation in master or slave modes.•Supports external clock frequencies up to SYSCLK / 2 in master mode and SYSCLK / 10 in slave mode.•Support for four clock phase and polarity options.•8-bit dedicated clock clock rate generator.•Support for multiple masters on the same data lines.System Management Bus / I2C (SMB0)The SMBus I/O interface is a two-wire, bi-directional serial bus. The SMBus is compliant with the System Management Bus Specifica-tion, version 1.1, and compatible with the I2C serial bus.The SMBus module includes the following features:•Standard (up to 100 kbps) and Fast (400 kbps) transfer speeds.•Support for master, slave, and multi-master modes.•Hardware synchronization and arbitration for multi-master mode.•Clock low extending (clock stretching) to interface with faster masters.•Hardware support for 7-bit slave and general call address recognition.•Firmware support for 10-bit slave address decoding.•Ability to inhibit all slave states.•Programmable data setup/hold times.External Memory Interface (EMIF0)The External Memory Interface (EMIF) enables access of off-chip memories and memory-mapped devices connected to the GPIO ports. The external memory space may be accessed using the external move instruction (MOVX) with the target address specified in either 8-bit or 16-bit formats.•Supports multiplexed memory access.•Four external memory modes:•Internal only.•Split mode without bank select.•Split mode with bank select.•External only•Configurable ALE (address latch enable) timing.•Configurable address setup and hold times.•Configurable write and read pulse widths.16/32-bit CRC (CRC0)The cyclic redundancy check (CRC) module performs a CRC using a 16-bit or 32-bit polynomial. CRC0 accepts a stream of 8-bit data and posts the result to an internal register. In addition to using the CRC block for data manipulation, hardware can automatically CRC the flash contents of the device.The CRC module is designed to provide hardware calculations for flash memory verification and communications protocols. The CRC module includes the following features:•Support for CCITT-16 polynomial (0x1021).•Support for CRC-32 polynomial (0x04C11DB7).•Byte-level bit reversal.•Automatic CRC of flash contents on one or more 1024-byte blocks.•Initial seed selection of 0x0000/0x00000000 or 0xFFFF/0xFFFFFFFF.3.7 AnalogProgrammable Current Reference (IREF0)The programmable current reference (IREF0) module enables current source or sink with two output current settings: Low Power Mode and High Current Mode. The maximum current output in Low Power Mode is 63 µA (1 µA steps) and the maximum current output in High Current Mode is 504 µA (8 µA steps).The IREF module includes the following features:•Capable of sourcing or sinking current in programmable steps.•Two operational modes: Low Power Mode and High Current Mode.10-Bit Analog-to-Digital Converter (ADC0)The ADC is a successive-approximation-register (SAR) ADC with 10- and 8-bit modes, integrated track-and hold and a programmable window detector. The ADC is fully configurable under software control via several registers. The ADC may be configured to measure different signals using the analog multiplexer. The voltage reference for the ADC is selectable between internal and external reference sources.•Up to 22 external inputs.•Single-ended 10-bit mode.•Supports an output update rate of 300 ksps samples per second.•Operation in low power modes at lower conversion speeds.•Asynchronous hardware conversion trigger, selectable between software, external I/O and internal timer sources.•Output data window comparator allows automatic range checking.•Support for burst mode, which produces one set of accumulated data per conversion-start trigger with programmable power-on set-tling and tracking time.•Conversion complete and window compare interrupts supported.•Flexible output data formatting.•Includes an internal 1.65 V fast-settling reference and support for external reference.•Integrated temperature sensor.Low Current Comparators (CMP0, CMP1)Analog comparators are used to compare the voltage of two analog inputs, with a digital output indicating which input voltage is higher. External input connections to device I/O pins and internal connections are available through separate multiplexers on the positive and negative inputs. Hysteresis, response time, and current consumption may be programmed to suit the specific needs of the application. The comparator module includes the following features:•Up to 12 external positive inputs.•Up to 11 external negative inputs.•Additional input options:•Capacitive Sense Comparator output.•VDD.•VDD divided by 2.•Internal connection to LDO output.•Direct connection to GND.•Synchronous and asynchronous outputs can be routed to pins via crossbar.•Programmable hysteresis between 0 and +/-20 mV.•Programmable response time.•Interrupts generated on rising, falling, or both edges.System Overview 3.8 Reset SourcesReset circuitry allows the controller to be easily placed in a predefined default condition. On entry to this reset state, the following occur:•The core halts program execution.•Module registers are initialized to their defined reset values unless the bits reset only with a power-on reset.•External port pins are forced to a known state.•Interrupts and timers are disabled.All registers are reset to the predefined values noted in the register descriptions unless the bits only reset with a power-on reset. The contents of RAM are unaffected during a reset; any previously stored data is preserved as long as power is not lost. The Port I/O latch-es are reset to 1 in open-drain mode. Weak pullups are enabled during and after the reset. For Supply Monitor and power-on resets, the RSTb pin is driven low until the device exits the reset state. On exit from the reset state, the program counter (PC) is reset, and the system clock defaults to an internal oscillator. The Watchdog Timer is enabled, and program execution begins at location 0x0000. Reset sources on the device include the following:•Power-on reset•External reset pin•Comparator reset•Software-triggered reset•Supply monitor reset (monitors VDD supply)•Watchdog timer reset•Missing clock detector reset•Flash error reset•RTC0 alarm or oscillator failure3.9 DebuggingThe EFM8SB2 devices include an on-chip Silicon Labs 2-Wire (C2) debug interface to allow flash programming and in-system debug-ging with the production part installed in the end application. The C2 interface uses a clock signal (C2CK) and a bi-directional C2 data signal (C2D) to transfer information between the device and a host system. See the C2 Interface Specification for details on the C2 protocol.3.10 BootloaderAll devices come pre-programmed with a UART bootloader.
