STM32平台uCOSIII移植

使用的软件及硬件平台：

硬件：德飞莱STM32开发板M3S（STM32F103ZE）软件：keil uVision4固件库：STM32F10x_StdPeriph_Lib_V3.5.0uCOSIII版本：Release V3.02.00 (2011/08/01)

建立工作目录

建立目录命名为uCOS，在uCOS目录下建立目录用于存放源文件、中间文件、工程文件及二进制文件。如下：
这里写图片描述
在uCOS-III目录下建立如下目录

工作目录创建完成后就可以将固件库及uCOS中文件复制到相应目录下，具体操作如下
1. 将\STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\STM32F10x_StdPeriph_Driver下的inc目录及src目录复制到FWLib目录下。
2. 将STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\CMSIS\CM3\CoreSupport目录下core_cm3.c和core_cm3.h复制到FWLib目录下。
3. 将STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x \startup\arm目录下starup_stm32f10x_hd.s复制到FWLib目录下
4. 将STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x下的.h及.c文件复制到FWLib目录下。
5. 将uCOS-III\Software\EvalBoards\Micrium\uC-Eval-STM32F107\IAR\BSP下的bsp.c及bsp.h复制到BSP目录下。同时在BSP\LED目录下建立led.c及led.h文件。
6. 将uCOS-III\Software\EvalBoards\Micrium\uC-Eval-STM32F107\IAR\uCOS-III-Ex1下的app.c、app_cfg.h复制到APP目录下同时建立app.h文件
7. 将uCOS-III\Software\uCOS-III\Cfg\Template目录下的文件复制到uCOS-III\Cfg目录下
8. uCOS-III\Software\uCOS-III\Ports\ARM-Cortex-M3\Generic\IAR目录下的文件复制到uCOS-III\Ports目录下。
9. 将uCOS-III\Software\uCOS-III\Source目录下文件复制到uCOS-III\Source目录下，同时将Software\EvalBoards\Micrium\ uC-Eval-STM32F107\IAR\uCOS-III-Ex1目录下的os_type.h复制到uCOS-III\Source目录下。
10. 将uCOS-III\Software\uC-CPU目录及下层目录下的所有.c及.h文件复制到uCOS-III\uC-CPU目录下
11. 将uCOS-III\Software\uC-LIB目录及下层目录下所有.c、.h及.asm文件复制到uCOS-III\uC-LIB目录下
12. 最后将STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\SysTick\ TimeBase目录下stm32f10x_conf.h、stm32f10x_it.c及ftm32f10x_it.h复制到BSP目录下。
13. 在User目录下建立main.c文件.

在keil中建立工程

打开keil软件，选择Project/new uvision project，将工程随意命名并放置在uCOSIII\Project目录下，保存之后选择器件，选择STMicroelectronics下的STM32F103ZE芯片。选择OK，在弹出的窗口选择否。不使用keil提供的文件。
选择manage components，建立相关工程目录如下图所示
这里写图片描述
uC-LIB目录按需添加。

之后添加文件到工程中，添加完成后如下图
这里写图片描述

添加完成后选择target option进行相应设置，如下
output->Create HEX File
c/c++->Define:STM32F10X_HD,USE_STDPERIPH_DRIVER
同时设置包含路径
这里写图片描述

修改文件

修改uCOSIII\Ports下os_cpu_a.asm文件
PUBLIC改为EXPORT
这里写图片描述

修改UCOSIII\uC-CPU下的cpu_a.asm文件
这里写图片描述
同时去掉该文件函数名后的”:”

修改FWLib下的startup_stm32f10x_hd.s文件
将文件中的PendSV Handler改为OS_CPU_PendSVHandler

以上修改完成后进行内核裁剪，修改UCOSIII\Cfg下的os_cfg.h文件，按需禁用，这次只保留基础功能

修改os_cpu_c.c文件注释或删除void OS_CPU_SysTickHandler（void）和void OS_CPU_SysTickInit（CPU_INT32U cnts）函数，同时将os_cpu_c.c中这两个函数的声明注释或删除。

在stm32f10x_it.c中添加

#include "os.h"

并将SysTick_Handler函数修改如下

void SysTick_Handler(void){  OSIntEnter();  OSTimeTick();  OSIntExit();}

LED测试

修改工程中文件
