STM32移植FreeRTOS到STM32F103STM32F103RCT6过程说明
1：新建MDK工程，选择文件存放路径，选择芯片型号，勾选产生HEX代码，创建一个USER文件，
复制自动创建的文件到USER文件中，关闭程序。
创建一个OBJ目标文件夹，打开软件选择目标文件保存位置到OBJ文件夹。
2：在项目新建分组USER, HARDWARE ,SYSTEM, FreeRTOS_CORE, FreeRTOS_PORTABLE , STM32F10X_FWLib, CORE 。
3：向FreeRTOS文件夹添加源码。如图：
include文件夹复制 Keil MenMang RVDS三个文件，其余不用。
4 ：向FreeRTOS_CORE和FreeRTOS_PORTABLE STM32F10X_FWLib, CORE 文件夹添加文件。
完成后如图
5：通过菜单栏 Project Options for Target Target 1 设置头文件路径。
6：复制原子的FreeRTOSConfig文件到 FreeRTOS文件夹的include文件中。
目前用的STM32F103RCT6，需按芯片容量修改函数。
7：如未使用原子FreeRTOS例程的sys和usart函数，需修改函数内容。
完成 编译。
