一、获取uC/OS-III源码

进入 Micrium 公司官网下载中心：http://micrium.com/downloadcenter/
选择ST 系列，点击 View all STMicroelectronics

或者直接在STM32F103C8T6移植uC/OS-III基于HAL库超完整详细过程博客中的链接中下载。

二、创建STM32Cube工程

选择stm32f103c8t6芯片，设置系统时钟为72M。

将PB0和PB1设置为GPIO_Output，用于和LED相连。

进行项目配置后，生成项目：

三、复制uC/OS-III文件到工程文件夹

在项目中创建一个UCOSIII文件夹：

将下载的源文件下的uC-CPU、uC-LIB、uCOS-III复制到该文件夹：

在Src文件夹下新建一个OS文件夹

将下载的源码中\\EvalBoards\\Micrium\\uC-Eval-STM32F107\\uCOS-III下的文件app.c 、 app_cfg.h 、 cpu_cfg.h 、 includes.h 、 lib_cfg.h 、 os_app_hooks.c 、os_app_hook.h、os_cfg.h、os_cfg_app.h复制到该OS文件夹中：

新建三个空白文件： bsp.c、bsp.h、app.h:

四、工程组件和头文件路径的添加

1. 工程分组的添加

打开工程，添加一下六个组：

2. 添加文件到分组

将Src/OS中的bsp.c 和 bsp.h文件添加至 bsp 组中，将 app.c 添加进 Application/User/Core 组中：

将UCOSIII/uC-CPU中的cpu_core.c、cpu_core.h、cpu_def.h添加进uCOSIII_CPU组中，同时将UCOSIII/uC-CPU/ARM-Cortex-M3/RealView中的三个文件添加到该组：

将UCOSIII/uC-LIB中的9个文件添加到uCOSIII-LIB组中，同时将UCOSIII/uC-LIB/Ports/ARM-Cortex-M3/Realview中的lib_mem_a.asm添加到该组中：

将UCOSIII/UcosIII/Ports/ARM-Cortex-M3/Generic/RealView中的3个文件添加的uCOSIII_Ports组中：

将UCOSIII/UcosIII/Source中的20个文件添加到uCOSIII_Source组中：

将Core/Src/OS中的以下图中的8个文件添加到OS_cfg组中：

3. 添加头文件路径

如图所示，添加头文件路径：

五、文件内容的修改

1. 启动文件

将启动文件下图中的PendSV_Handler和Systick_Handler改为OS_CPU_PendSVHandler和OS_CPU_SysTickHandler：

下图类似：

2. app_cfg.h

修改前：

#define APP_CFG_SERIAL_EN  DEF_ENABLED

修改后：

#define APP_CFG_SERIAL_EN  DEF_DISABLED

修改前:

#define APP_TRACE  BSP_Ser_Printf

修改后:

#define APP_TRACE  (void)

3. includes.h

添加3个头文件:

#include "gpio.h"
#include "app_cfg.h"
#include "app.h"

修改前:

#include <stm32f10x_lib.h>

修改后:

#include "stm32f1xx_hal.h"

4. bsp.c和bsp.h

bsp.c全部改为：

// bsp.c
#include "includes.h"

#define  DWT_CR      *(CPU_REG32 *)0xE0001000
#define  DWT_CYCCNT  *(CPU_REG32 *)0xE0001004
