STM32F103 FreeRTOS记录

                                  STM32F103 FreeRTOS记录

一、移植（测试翻转led）

1.添加freertos9.0相关文件。

2.在配置头文件添加下面代码，并注释掉stm32f10x_it.c文件里的相关函数

#define vPortSVCHandler SVC_Handler
#define xPortPendSVHandler PendSV_Handler
#define xPortSysTickHandler SysTick_Handler

3.设置：  NVIC_PriorityGroupConfig(NVIC_PriorityGroup_4);

4.代码如下：
