一、基于STM32CubeMX建立工程

1、配置RCC

2、配置SYS

3、配置PB0和PB1设置为GPIO_Output，用于和LED相连。

4、配置USART1

5、生成代码

二、获取uC/OS-III源码

官网下载地址：http://www.silabs.com/developers/micrium
网盘下载：http://pan.baidu.com/s/1pXIbNB2pX5gVCKOaRIDuuw
提取码：lzjl

三、复制uC/OS-III文件到工程文件夹

在生成的keil工程文件夹f103c8_uCOSIII_1_test中新建一个UCOSIII的文件夹，将我们下载的源代码中三个文件夹：Uc-CPU、 uC-LIB、 Ucos-III 复制到我们新建的文件夹中：

在Src文件夹下新建一个OS文件夹

将刚才下载源码打开，将路径：\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复制到上一步建立的OS文件夹中，同时新建三个空白文件： bsp.c、bsp.h、app.h

最后在OS文件夹中新建三个空白文件： bsp.c、bsp.h、app.h

四、添加工程组件和头文件路径

1、添加工程分组

打开工程，添加以下六个组

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

五、修改文件内容

1.启动文件

2. app_ cfg.h

• #define APP_CFG_SERIAL_EN DEF_ENABLED修改为#define APP_CFG_SERIAL_EN DEF_DISABLED
• #define APP_TRACE BSP_Ser_Printf修改为#define APP_TRACE (void)

3. includes.h

• 添加三个头文件：#include "gpio.h"、#include "app_cfg.h"、#include "app.h"
  
• #include 修改为#include "stm32f1xx_hal.h"

4. bsp.c和bsp.h

• bsp.c:

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

6. lib_ cfg.h

• 加入宏定义：#define LIB_MEM_CFG_HEAP_SIZE 10u * 1024u

7. app.c和app.h

• app.c只有一行：#include "includes.h"
• app.h

// app.h
