1. 手动移植FreeRTOS V9.00到 Stm32F103C8T6

记录移植过程，以便以后查看：

附上FreeRTOS源码和  测试文件：

提取码：1234

1.使用cubeMAX配置一个工程

a.选择单片机型号：

b。设置SWD调试，选TIM4作为系统时钟，systick要用来跑freeRTOS

c.NVIC默认使用Group4

配置GPIO，我这里配置了两个引脚，作为LED输出

d,RCC都选外部晶振

e。配置时钟树，HCLK 72Mhz

f。project 配置我使用MDK ，5.27版本，其他默认

g.这里我配置使用必需的库并单独生成.c和.h

f.创建代码，结束创建

2.下载 freeRTOs源码

3.在我自己创建的工程里面新建FreeRTOS文件，结构如下：

把源码的FreeRTOSv9.0.0\FreeRTOS\Source 文件夹下的c文件复制到src中，

把FreeRTOSv9.0.0\FreeRTOS\Source\portable\MemMang中内存管理文件   heap_4.c 加到port中

FreeRTOSv9.0.0\FreeRTOS\Source\portable\RVDS\ARM_CM3 下文件加入port

FreeRTOSv9.0.0\FreeRTOS\Demo\CORTEX_STM32F103_Keil 下FreeRTOSConfig.h文件放到port中

FreeRTOSv9.0.0\FreeRTOS\Source\include  头文件放到Inc中

最后如下：

4.打开keil工程，添加头文件和源文件

5.修改freeRTOS config 文件：具体参考如下：

6.编译工程，会发现这个问题

找到中断处理函数，屏蔽这三个中断即可

7.编译成功后，创建一个任务，测试两个LED是否是一起亮一起灭，如果是就说明成功了
