打开stm32 cubeMX,选择芯片stm32f103c8,配置系统时钟为72M,作为移植测试,将与LED相连的两个端口PB0,PB1配置为GPIO_Output,可根据LED现象作为我们是否移植成功的依据。
生成keil工程后的文件夹:
\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
打开f103c8_uCOSIII_1_test工程, 按照如图所示添加六个新的组: bsp、uCOSIII_CPU、 uCOSIII_LIB、 uCOSIII_Ports、 uCOSIII_Source、 OS_cfg

其中执行任务的程序:
实现的功能是:使LED0不停的闪烁,同时点亮LED1。
这个头文件中有一个宏定义:
#define LIB_MEM_CFG_HEAP_SIZE 27u * 1024u
表示把堆的空间设置为27KB,但是我使用的stm32f103c8t6的RAM总共才20K:
所以这里需要将堆空间改小一点,我改成了10K
#define LIB_MEM_CFG_HEAP_SIZE 10u * 1024u
此处的修改若是对于RAM空间较大的单片机是没有必要的,但是对于小容量的单片机则是必须的。
编译报错内存不足
.\Objects\ucos-led.axf: Error: L6406E: No space in execution regions with .ANY selector matching os_cfg_app.o(.bss).
解决方法:修改堆的大小:LIB_MEM_CFG_HEAP_SIZE
可以参考:https://www.cnblogs.com/zhangyi-studio/p/RTOS.html
编译无错误,程序运行没有现象
好不容易按照上面的步骤移植完成,也终于没有了满屏的error。赶紧下载到开发板上,谁曾想板子上的两个LED依然一动不动。
这时候点开Debug,单函数运行,知道运行到这里程序卡死了:
退出Debug的时候,程序其实是卡在了这里:
这还是启动文件的部分,我们第一步修改的就是启动文件,再来看一遍
修改前:
PendSV_Handler
SysTick_Handler
修改后:
OS_CPU_PendSVHandler
OS_CPU_SysTickHandler
仔细对比一下,不仅仅是在原先的函数名上添加前缀OS_CPU_,修改后Handler前面的下划线"_"是被删除了的。
