STM32F103C8移植uC/OSIII并以不同周期点亮两个LED灯（HAL库方式）【uC/OS】【STM32开发板】【STM32CubeMX】
实验说明
将嵌入式操作系统uC/OSIII移植到STM32F103C8上，构建两个任务，两个任务分别以1s和3s周期对LED进行点亮—熄灭的控制。
获取uC/OSIII源码
链接：https://pan.baidu.com/s/1Axjz1ptMjIPcH6_0tjKKDw
提取码：ucos
建立STM32CubeMX项目
选择STM32F103C8T6芯片，设置PB0和PB1为GPIO_Output，用于和LED相连。
如下图设置时钟为72MHz。
配置其它参数后，生成Keil项目。
复制uC/OS-III文件到项目文件夹
在生成的项目文件夹下新建一个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，如下图：
在Core\Src文件夹下新建OS文件夹，将下载的源码中uCOS-CONFIG中的文件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，并新建bsp.c, bsp.h文件，如下图：
添加项目组件和头文件路径
添加项目分组
在生成的Keil项目中添加六个新组：bsp, uCOSIII-CPU, uCOSIII-LIB, uCOSIII-Port, uCOSIII-Source, OS-cfg, 如下图：
添加文件到分组
将Core\Src\OS路径下的bsp.c和bsp.h文件添加至bsp组中，如下图：
将uCOSIII\uC-CPU路径下的所有文件及uCOSIII\uC-CPU\ARM-Cortex-M4\RealView路径下的所有文件添加至uCOSIII-CPU组中，如下图：
将uCOSIII\uC-LIB路径下的所有文件及uCOSIII\uC-LIB\Ports\ARM-Cortex-M4\RealView路径下的所有文件添加至uCOSIII-LIB组中，如下图：
将uCOSIII\uCOS-III\Ports\ARM-Cortex-M4\Generic\RealView路径下的所有文件添加至uCOSIII-Port组中，如下图：
将uCOSIII\uCOS-III\Source路径下的所有文件添加至uCOSIII-Source组中，如下图：
将Core\Src\OS路径下除bsp.c, bsp.h外的所有文件添加至OS-cfg组，如下图：
添加头文件路径
点击Options for Target，点击C/C++，在Include Path栏中添加以下路径：
修改文件内容及编写程序
启动文件 (startup_stm32f103xb.s)
将启动文件中的PendSV_Handler和Systick_Handler改为OS_CPU_PendSVHandler和OS_CPU_SysTickHandler，如下图：
app_cfg.h
#define APP_CFG_SERIAL_EN DEF_ENABLED改为#define APP_CFG_SERIAL_EN DEF_DISABLED；#define APP_TRACE BSP_Ser_Printf改为#define APP_TRACE (void)。
includes.h
在#include <bsp.h>下添加#include "gpio.h", #include "app_cfg.h"；#include <stm32f10x_lib.h>改为#include "stm32f1xx_hal.h"。
bsp.c和bsp.h

该文件中有一个宏定义：
#define LIB_MEM_CFG_HEAP_SIZE 27u * 1024u
STM32F103C8T6的RAM仅有20KB，因此需要将堆空间改小，这里改成10KB：
#define LIB_MEM_CFG_HEAP_SIZE 10u * 1024u
main.c
我在main.c中创建了两个任务：LED0_Task控制B0端口的LED灯以1s为周期亮—灭；LED1_Task控制B1端口的LED灯以3s为周期亮—灭。
