一、STM32CubeMX基于HAL库建立工程
1、配置RCC
2、配置SYS
3、配置GPIO输出口
4、串口配置
5、系统时钟频率配置
二、uC/OS-III下载
百度网盘链接：百度网盘 请输入提取码 提取码：3123
下载后有文件如下：
三、文件移植
1、uC-BSP文件夹中添加文件
新建文件夹uC-BSP，新建空的bsp.c和bsp.h文件
2、uC-CONFIG文件夹中添加文件
新建文件夹uC-CONFIG，添加如下目录文件，这里的app.c文件相当于mian.c文件，可以直接用mian.c，而不用添加app.c文件
3、HAL工程的MDK-ARM文件夹设置
将uCOS-III相关文件添加进HAL工程的MDK-ARM中，同时新建uC-PORT和uC-SOURCE文件夹
4、uC-CPU文件夹设置
将该目录下的三个文件复制到uC-CPU目录下，这样添加目录的时候只需要添加uC-CPU
5、uC-LIB文件夹设置
将该目录下的文件复制到uC-LIB根目录下这样添加文件路径时只需添加uC-LIB
6、uC-PORT文件夹中添加文件
将该目录下的三个文件复制到uC-PORT中
7、uC-SOURCE文件夹中添加文件
将该目录下的文件复制到uC-SOURCE文件中
四、keil文件配置
1、勾选Reset and Run
小魔术棒-Debug-Use（ST-Link Debugger）-Settings-Flash Download
2、添加文件组
右键oc-os-test1，添加新组
3、为新添加的组添加相应文件
右键各新组，选择添加以存在文件，选择相应的目录，注意勾选All files，否则可能会少添加文件，这里以为uC-CPU添加文件为例
4、导入文件路径
五、代码修改
1、为bsp.c和bsp.h添加代码

3、startup_stm32f103xb.s文件修改
在75，75，173，174，177和178行处将PendSV_Handler和SysTick_Handler改为OS_CPU_PendSVHandler和OS_CPU_SysTickHandler
4、app_cfg.h文件修改
5、includes.h文件修改
添加#include "gpio.h"和#include "app_cfg.h"这两个头文件
6、lib_cfg.h文件修改
因为STM32F103C8T6的ARM只有20K大小，所以这里改为10
