STM32学习笔记9——移植FreeRTOS

开发环境
硬件环境：STM32F103C8T6
软件环境：STM32CubeIDE1.4.0

前置条件

• 准备一个工程
• 下载FreeRTOS的源码

FreeRTOS移植

1.移植FreeRTOS源码

• 在工程文件中新建文件夹 —— FreeRTOS(存储FreeRTOS源码)
  
  *打开 FreeRTOS 源码文件夹, 将其中的include文件夹复制到刚刚新建的FreeRTOS文件夹中。
  
• 然后include同目录下新建一个文件夹——portable
• 进入portable文件夹，在FreeRTOS源码文件夹的FreeRTOSv202012.00\FreeRTOS\Source\portable\GCC\ARM_CM3的路径下，将port.c和portmacro.h文件复制到刚刚新建的protable文件夹中，并将FreeRTOSv202012.00\FreeRTOS\Source\portable\MemMang路径下的heap_4.h也复制到protable文件夹中，此时文件夹中存在以下三个文件。
  
• 再次打开FreeRTOS源码文件夹，在FreeRTOSv202012.00\FreeRTOS\Source路径下，将所有的.c文件复制到工程的FreeRTOS文件夹中。
  

2. 拷贝FreeRTOSConfig.h文件到src文件夹中

• 打开FreeRTOS源码文件夹，在FreeRTOSv202012.00\FreeRTOS\Demo\CORTEX_STM32F103_Primer_GCC路径下，将FreeRTOSConfig.h文件拷贝到工程的src文件夹下。
  
  3.配置FreeRTOS源码到工程文件中
  右键点击工程名——点击Properties进入配置页——点击Paths and Symbols选项——添加Includes路径
  
  选择Source Location添加源文件路径
  
  4.修改FreeRTOSConfig.h文件
