FreeRTOS

官网

文件中只保留E:\a学习\9.myOC\FreeRTOS\FreeRTOSv202212.01\FreeRTOS\Demo文件夹下面的CORTEX_STM32F103_Keil, 其他的文件暂时用不到

source文件是核心文件

只保留以上的文件, 之后打开项目

之后编译文件, 选择用keil5进行格式转换

发现Common目录不能少, 重新添加

原有的文件是在lcd上面打印文字, 但是没有配套的板子

目录分析

• Demo是一系列的工程文件

下面是各种芯片的项目文件

• source是核心文件, 事件组, 链表, 队列, stream buff, 任务, 定时器

portable是可移植文件, 顶层目录是各种编译器, keil下面显示看RVDS, RVDS下面是各种架构

编程规范

后面的变量经常作为返回值

这个文件在source/portable/ARM_CM3

• 变量名:

• 函数名

返回值类型 + 实现的文件名 + 函数的功能

prv表示私有函数

• 宏的名字

小写代表的是文件名字
