STM32F103ZE FreeRTOS移植、测试

一、前期准备 

单片机：STM32F103ZET6 

开发环境：MDK5.14 

库函数：标准库V3.5 

FreeRTOS：V9.0.0（网上下载，官网上目前是V10.0.1）

二、实验效果 

总共6个任务，串口1、串口2、4个RGB小灯以不同频率闪烁。5050 RGB LED驱动请参考RGB驱动，串口1、2同时打印测试信息。 

三、移植准备 

下载好的FreeRTOS源码中，只需要把Source文件夹加入工程。 

1.FreeRTOS内核文件，如下图所示，里面所有C文件加入到工程里面 

2.将portable中无关文件夹删除掉，只留下如图所示的三个文件夹。Keil文件夹不用管，MemMang里面是heap1.c~heap5.c文件，这个是内存管源码，这里移植将heap4.c加入工程。RVDS中ARM_M3的C文件加入工程 

3.Keil工程 

4.修改stm32启动文件 

四、测试代码 

完整工程请加QQ：1002521871，验证：呵呵
