使用 Clion (cmake) 开发FreeRTOS

这里使用的是 f407

1. 先用STM32CubeMX 建立一个可以运行的stm32项目，toolchain选择 SW4STM32

2. 官网下载源码

www.freertos.org

我这里下载的是FreeRTOSv202112.00.zip

解压缩后得到

需要以下几个文件夹或档案

FreeRTOS/Source下的所有的 .c 档案

FreeRTOS/Source/include

FreeRTOS/Source/portable/GCC/ARM_CM4F

FreeRTOS/Source/portable/MemMang里面的heap_4.c ( 可以参考 FreeRTOS基础二：堆内存管理之heap_4方案_哈士奇上蔚的博客-CSDN博客)

3.. 将 FreeRTOS/Demo/CORTEX_M4F_STM32F407ZG-SK里的FreeRTOSConfig.h拷贝到 FreeRTOS/Source/include 下面

全部需要的档案如下

把FreeRTOS的文件夹放到项目的根目录

4. 修改 FreeRTOSConfig.h

将45行的

#ifdef __ICCARM__

#include

extern uint32_t SystemCoreClock;

#endif

修改为

#if defined (__ICCARM__) || defined (__CC_ARM) || defined (__GNUC__)

#include

extern uint32_t SystemCoreClock;

#endif

或是直接去掉 #ifdef __ICCARM__的判断

将51行的configUSE_IDLE_HOOK 改为0

将52行的configUSE_TICK_HOOK改为0

将64行的configCHECK_FOR_STACK_OVERFLOW改为0

将66行的configUSE_MALLOC_FAILED_HOOK改为0

5. 修改cmake

在cmake里启用硬件浮点运算单元 FPU

#Uncomment for hardware floating point

add_compile_definitions(ARM_MATH_CM4;ARM_MATH_MATRIX_CHECK;ARM_MATH_ROUNDING)

add_compile_options(-mfloat-abi=hard -mfpu=fpv4-sp-d16)

add_link_options(-mfloat-abi=hard -mfpu=fpv4-sp-d16)

cmake里添加include path

FreeRTOS/Source/include

FreeRTOS/Source/portable/GCC/ARM_CM4F

cmake里添加

file(GLOB_RECURSE SOURCES "FreeRTOS/*.*")

6. 将 stm32f4xx_it.c 里的

SVC_Handler

PendSV_Handler

SysTick_Handler

三个方法前面都加上__weak

因为这三个方法在我们添加的 FreeRTOS/Source/portable/GCC/ARM_CM4F/prot.c文件里有定义，会导致重定义

7. 修改main函数运行

以下是代码。完整项目可以在这里下载，硬石YS-F4Pro （f407）开发板可以直接运行
