【STM32F723 Discovery Kit】移植FreeRTOS系统 [复制链接]

这篇来学习下在STM32F723开发板上移植FreeRTOS系统。

 

一、下载FreeRTOS源码

 

下载地址：https://www.freertos.org/zh-cn-cmn-s/a00104.html

 

二、复制文件

 

2.1、复制下载的freertos源文件添加到工程中

 

在demo中找一个M7开发板的例程，复制FreeRTOSConfig.h

 

 

2.2、添加文件到工程

 

2.3、添加头文件

 

添加完成后，编译项目根据编译提示错误修改FreeRTOSConfig.h文件的配置。

 

三、测试源码
