一、使用STM32CubeMX生成工程
1. 打开软件
2. 基于芯片创建工程
3. 选择对应芯片
- 此处我是采用的stm32f429igt6
4. 设置GPIO
5. 设置串口
6. 设置时钟为180MHz
- 此处选用内部时钟，如需外部时钟请自定义配置
7. 工程设置
8. 生成工程，编译运行，验证
二、LiteOS文件移植
1. 获取源码
2. 下载到本地，解压如图所示
3. 复制源码文件到mdk工程目录
- 打开STM32CubeMX生成的工程目录，添加
LiteOS文件夹，将步骤二的三个文件夹复制到此文件夹
三、MDK工程分组目录及头文件设置
1. 添加分组目录
LiteOS/archLiteOS/kerneltLiteOS/config
2. 添加LiteOS/arch分组文件
3. 添加LiteOS/kernel分组文件
kernel/los_init.c
kernel/base/core
kernel/base/ipc
kernel/base/mem/bestfit_little
kernel/base/mem/common
kernel/base/mem/membox
kernel/base/misc
kernel/base/om
kernel/extended/tickless
4. 添加LiteOS/config分组文件
5. 添加头文件路径
- 按下图新增头文件路径
四、MDK源码修改，创建TencentOS tiny任务
1. 修改stm32f4xx_it.c中断配置文件
- 屏蔽
PendSV_Handler和SysTick_Handler函数
2. 修改target_config.h函数

3. 在main.c函数中新建任务
main.c源码如下

4. 观察现象
- led灯闪烁，同时串口打印数据
