SDK–Components3200Prerequisite(continued)3Foundation SDK–ComponentsThe CC3200Foundation SDK package includes two main building blocks:•SimpleLink Library–This library hosts APIs that serve the connectivity features.•Peripheral Driver Library–This library hosts APIs to access MCU peripherals.This section also lists the sample and reference applications packaged in the Software Development Kit.3.1SimpleLink Component Library3.1.1SimpleLink Modular DecompositionFigure7.SimpleLink Modular CompositionTI SimpleLink Framework provides a wide set of capabilities,including basic device management through wireless network configuration,BSD socket services,and more.For better design granularity,thesecapabilities are segregated into individual modules.Each module represents different functionality orcapability of the SimpleLink Framework.The following list enumerates the different components in the SimpleLink Framework:13 SWRU369B–June2014–Revised

Rx/Txnetapp•DNS Resolution•Ping remote device•Address Resolution Protocolnetcfg•IP/MAC address configurationfs•File system Read/Write3.1.2Using the TI SimpleLink FrameworkTI SimpleLink Framework provides a rich,yet simple set of APIs.For detailed information on the APIs and their usage,refer to the document docs\simplelink_api\programmers_guide.html available in the SDK.TI SimpleLink Framework has a ready-to-use port available in the CC3200Foundation SDK.The source code is also shared if further customization is desired by the developer.The following note describessimple possible customizations and the associated procedure.Note:All modifications and adjustments to the driver should be made in the user.h header file only,toensure a smooth transaction to future versions of the driver.Modify user.h file–Modify the user.h file that includes the default configurations and adjustments.Select the capabilities set required for your application–TI has focused on building a set ofpredefined capability sets that fit most target applications.TI recommends trying and choosing one ofthese predefined capabilities sets before building a customized set.Once a compatible set is found,skip the rest of this step.The available sets are:•#SL_TINY–Compatible with platforms with very limited resources.Provides the best-in-class footprint in terms of code and data consumption.•#SL_SMALL–Compatible with most common networking applications.Provides the most common APIs with a balance between code size,data size,functionality,and performance.•#SL_FULL–Provides access to all SimpleLink functionalities.Memory management model–The SimpleLink driver supports two memory models:•Static(default)•DynamicThe CC3200default configuration is Static.In the dynamic model,the configuration uses the malloc and free,as defined by the operating system.If the user wishes to define their own memory management,they can define these interfaces.Asynchronous event handlers routines–The SimpleLink device generates asynchronous events in several situations.These asynchronous events could be masked.Provide handler routines to catch these events.If a handler routine was not provided and the event is received,the driver will drop this eventwithout any indication of a drop.Interface communication driver–The CC3200host driver implements SPI communication interface.The interface for this communication channel includes four simple access functions:1.open2.close3.read14SWRU369B–June2014–Revised March2015 CC3200SimpleLink™Wi-Fi®and IoT Solution,a Single Chip Wireless MCUSubmit Documentation Feedback Foundation SDK–Components4.writeThe CC3200,SPI implementation uses DMA to increase the utilization of the communication channel.OS adaptation–The SimpleLink driver can run on two kinds of platforms:•Non-OS/Single-Threaded(default)•Multi-ThreadedThe CC3200SimpleLink host driver is ported on both Non-OS and Multi-Threaded OS environments.The host driver is made OS-independent by implementing an OS Abstraction layer.Reference implementation for OS Abstraction is available for FreeRTOS and TI-RTOS.To work in a multi-threaded environment under a different operating system,provide some basicadaptation routines to allow the driver to protect access to resources for different threads(locking object) and to allow synchronization between threads(sync objects).In addition,the driver support runs without a dedicated thread allocated solely to the SimpleLink driver.To work in this mode,supply a spawn method that enables functions to run on a temporary context.15 SWRU369B–June2014–Revised March2015CC3200SimpleLink™Wi-Fi®and IoT Solution,a Single Chip Wireless MCU Submit Documentation FeedbackFoundation SDK–Components 3.1.3Switch

本文更新的文件是利用TFTP协议[1]来传输，由于TFTP协议不支持用户交互，这样无疑增加了用户的难度，所以这里用JSON[2]来传输文件名和命令操作指令，使得可以具有保持TFTP协议特性的同时也具有可交互。
通过本文的方法可以在产品运行的同时，实施对文件的更新，而且可以为用户提供类似网盘的数据存储。
该系统的硬件主要是CC3200核心模块(见图1)与SD卡槽(见图2)连接而成，SD卡只要三个线连接到核心板上即可，即SD_CMD、SD_CLK、SD_DATA分别连接到核心板上的PIN02、PIN01、PIN64，这三个引脚是CC3200为连接SD卡而预留的特定引脚。
核心板上的S10是拨码开关，这样可以选择不同的程序载入模式，P10是为了测电流而预留的引脚，可以直接连接；SD卡槽三个连接芯片引脚必须接上拉电阻。

CC3200云平台接入方法
CC3200云平台接入方法前言CC3200是TI无线连接SimpleLink Wi-Fi和物联网（IoT）推出的一款业界第一个具有内置Wi-Fi的芯片方案，它主要是针对物联网应用，其内部集成高性能ARM Cortex-M4的MCU。
客户能够使用单个集成电路开发整个应用，借助片上Wi-Fi、互联网和强大的安全协议即可实现快速的物联网开发。
OneNET是由移动公司所开发的专业化物联网开放平台。
平台着眼于适配各种网络环境和协议类型，支持各类传感器和智能硬件的快速接入，提供丰富的API支持各类行业应用和智能硬件的开发，能够有效降低物联网应用开发和部署成本，满足物联网领域设备连接、协议适配、数据存储、数据安全、大数据分析等平台级服务需求。
OneNET作为平台的平台，旨在为各个业务平台提供接入、传输、存储和展现等基础设施，降低开发成本。
物联网的含义物联网是新一代信息技术的重要组成部分，也是“信息化”时代的重要发展阶段。
其英文名称是：“Internet of things（IoT）”。
顾名思义，物联网就是物物相连的互联网，这包含两层含义：其一是物联网的核心和基础仍然是互联网；其二是用户端概念延伸和扩展到了任何物体与物体之间，进行信息交换和通信。
物联网是各种感知技术的广泛应用，物联网不仅仅提供传感器的连接，其本身也具有智能处理的能力，能够对物体实施智能控制。
物联网将传感器和智能处理相结合，利用云计算、模式识别等各种智能技术，扩充其应用领域，也因此被称为继计算机、互联网之后世界信息产业发展的第三次浪潮。
物联网是互联网的应用拓展，与其说物联网是网络，不如说物联网是业务和应用。
因此，应用创新是物联网发展的核心，以用户体验为核心的创新2.0是物联网发展的灵魂。
国际电信联盟2005年一份报告曾描绘“物联网”时代的图景：当司机出现操作失误时汽车会自动报警；公文包会提醒主人忘带了什么东西；衣服会“告诉”洗衣机对颜色和水温的要求等等。

TX power level = 4 implies output power backed off approximately 4 dB.(2) The CC3200 system is a constant power-source system. The active current numbers scale based on the VBAT voltage supplied. (3) DTIM = 1(4) LPDS current does not include the external serial flash. The LPDS number reported is with retention of 64KB MCU SRAM. The CC3200 device can be configured to retain 0KB, 64KB, 128KB, 192KB or 256KB SRAM in LPDS. Each 64KB retained increases LPDS current by 4 µA. (5) Serial flash current consumption in power-down mode during hibernate is not included. (6) The complete calibration can take up to 17 mJ of energy from the battery over a time of 24 ms . Calibration is performed sparingly, typically when coming out of Hibernate and only if temperature has changed by more than 20°C or the time elapsed from prior calibration is greater than 24 hours.2.3 Receiver CharacteristicsTA = +25°C, VBAT = 2.1 to 3.6 V.

Layout Guide8.1 RF SectionBeing a wireless device, the RF section gets the top priority in terms of layout. It is very important for the RF section to be laid out correctly in order to get the optimum performance from the device. A poor layout can cause performance degradation for the output power, the error vector magnitude (EVM), the sensitivity, and the spectral mask.8.2 Antenna Placement and RoutingThe antenna is the element used to convert the guided waves on the PCB traces to the free-space electromagnetic radiation. The placement and layout of the antenna is key to increased range and data rates. The guidelines in Table 1 need to be observed for the antenna. Table 1. Antenna Guidelines Sr No 1 2 3 Guidelines Place the antenna on an edge or corner of the PCB. Make sure that no signals are routed across the antenna elements on all the layers of the PCB. Most antennas, including the chip antenna used on the BoosterPack, require ground clearance on all the layers of the PCB. Ensure that the ground is cleared on inner layers as well. 4 Ensure that there is provision to place matching components for the antenna. These need to be tuned for best return loss once the complete board is assembled. Any plastics or casing should also be mounted while tuning the antenna as this can impact the impedance. 5 Ensure that the antenna impedance is 50 Ω as the device is rated to20work only with a 50 Ω system.6 In case of printed antenna, ensure that the simulation is performedwith the solder mask in consideration.7 Ensure that the antenna has a near omni-directional pattern.8 The return loss measured at the filter out (looking into the device)should be better than -10dB. To ease the FCC, CE, andETSI certification, the antenna used should be of the same gain orlesser.Table 2.

This structure offers the maximum isolation across filter gap and the best possible shielding to the RF lines. In addition to the ground on the L1 layer, placing GND vias along the line also provides additional shielding.The recommended values for the PCB are provided in Table 4.Table 4.
