+
+单片机可复用、可通用开发组件，是以中间件思想开发的一套功能模块，将具有代表性或使用次数较多的功能和协议栈封装为独立的组件供开发者使用，开发者仅需通过组件提供的接口对接驱动层和应用层即可使用组件功能，从而减少重复工作、缩短开发周期，并且具备跨平台特性。
+
+## 代码结构
+
+本组件处在中间件层，向上提供应用层的功能模块接口，向下调用底层驱动接口。

+## 文件目录
+
+* ./documents/存放组件使用手册
+* ./examples/存放所有组件的使用例程(用前必看)
+* ./src/存放所有组件源代码
+
+## 使用说明
+
+- MCU开发项目编译器需要勾选C99
+- 使用前请先查看例程，例程项目和组件名称相同
+- 所有组件都必须包含common_include.c.h文件

 ================================================================================
 使用步骤
 ================================================================================
 1）使用J-Link连接目标板；
 2）打开工程，重新编译，启动调试或直接下载程序运行；
-3）用J-Link RTT Viewer软件连接，等待发送串口数据后查看打印消息；
-3）打开串口调试软件，发送结尾是\r\n的任意数据。
+3）第一次烧写应全片擦除一次，然后按顺序烧写bootloader，application，factory程序；
+3）用户可更换通信协议，将组件接口对接好即可使用。

 注意
 ================================================================================
+1）用户根据需求可前往源码头文件修改宏定义参数

+
+================================================================================
+功能描述
+================================================================================
+本用例展示了bootloader_app例程的使用方法，正常情况下，设备执行的是此程序。
+
+================================================================================
+测试环境
+================================================================================
+测试用板:
+---------------------
+任意开发板
+
+辅助工具:
+---------------------
+J-Link
+串口工具
+
+辅助软件:
+---------------------
+J-Link RTT Viewer
+串口上位机(需支持ymodem协议)
+
+源码文件:
+---------------------
+bootloader.c
+bootloader.h
+
+================================================================================
+使用步骤
+================================================================================
+1）使用J-Link连接目标板；
+2）打开工程，重新编译，启动调试或直接下载程序运行；
+3）该程序现象为设备led指示灯以1s周期翻转；
+4）使用串口上位机先发送'@'字符再以ymodem协议发送升级bin文件；
+5）查看用户设置的升级程序现象，出现预期现象则表明升级成功，若升级失败则执行备份
+   (出厂)程序。
+
+================================================================================
+注意
+================================================================================
+1）用户根据需求可前往源码头文件修改宏定义参数
+

+
+================================================================================
+功能描述
+================================================================================
+本用例展示了bootloader_factory例程的使用方法，该例程为备份(出厂)程序，升级失败后会
+跳转到此程序执行。
+
+================================================================================
+测试环境
+================================================================================
+测试用板:
+---------------------
+任意开发板
+
+辅助工具:
+---------------------
+J-Link
+串口工具
+
+辅助软件:
+---------------------
+J-Link RTT Viewer
+串口上位机(需支持ymodem协议)
+
+源码文件:
+---------------------
+bootloader.c
+bootloader.h
+
+================================================================================
+使用步骤
+================================================================================
+1）使用J-Link连接目标板；
+2）打开工程，重新编译，启动调试或直接下载程序运行；
+3）该程序现象为设备led指示灯以500ms周期翻转；
+4）使用串口上位机先发送'@'字符再以ymodem协议发送升级bin文件；
+5）查看用户设置的升级程序现象，出现预期现象则表明升级成功。
+
+================================================================================
+注意
+================================================================================
+1）用户根据需求可前往源码头文件修改宏定义参数
+

+功能描述
+================================================================================
+本用例展示了xmodem协议组件的使用方法。
+
+================================================================================
+测试环境
+================================================================================
+测试用板:
+---------------------
+任意开发板
+
+辅助工具:
+---------------------
+J-Link
+
+辅助软件:
+---------------------
+J-Link RTT Viewer
+SecureCRT串口软件
+
+源码文件:
+---------------------
+xmodem.c
+xmodem.h
+
+================================================================================
+使用步骤
+================================================================================
+1）使用J-Link连接目标板；
+2）打开工程，重新编译，启动调试或直接下载程序运行；
+3）用J-Link RTT Viewer软件连接，查看打印消息；
+4）用SecureCRT串口软件连接设备串口，点击工具栏Transfer->Send Xmodem
+   或Transfer->Receive Xmodem选项开始传输
+
+================================================================================
+注意
+================================================================================
+1）用户根据需求可前往源码头文件修改宏定义参数

+================================================================================
+测试环境
+================================================================================
+测试用板:
+---------------------
+任意开发板
+
+辅助工具:
+---------------------
+J-Link
+
+辅助软件:
+---------------------
+J-Link RTT Viewer
+SecureCRT串口软件
+
+源码文件:
+---------------------
+ymodem.c
+ymodem.h
+
+================================================================================
+使用步骤
+================================================================================
+1）使用J-Link连接目标板；
+2）打开工程，重新编译，启动调试或直接下载程序运行；
+3）用J-Link RTT Viewer软件连接，查看打印消息；
+4）用SecureCRT串口软件连接设备串口，点击工具栏Transfer->Send Ymodem
+   或Transfer->Receive Ymodem选项开始传输
+
+================================================================================
+注意
+================================================================================
+1）用户根据需求可前往源码头文件修改宏定义参数
