STM32F407移植uCOSII笔记

1、STM32F407在IAR环境下移植Ucos-II第一步：安装IAR for ARM。第二步：建一个文件夹，最好用工程名命名。第三步：在新建的文件夹下面建7个文件夹，分别是：app、bsp、libraries、Project、si、ucos-ii、user，建好的文件夹见下图（图一）：图 1第四步：准备好STM32F4XX的固件库。见图二、图三：图 2图 3第五步：准备好uCOS-II源码。我的源码路径为：E:项目文件电阻焊控制器V2参考资料ucos源码MicriumSoftwareuCOS-II；见图4、图5、图6、图7、图8：图 4图 5图 6图 7图 8第六步：将第四步中准备好的stm3

2、2固件库里libraries下的文件拷贝到工程文件夹下的libraries文件夹里。第七步：将第五步中准备好的uCOS-II源码文件夹里的Ucos-II文件夹中的ports、source两个文件夹拷贝到工程文件夹下的ucos-ii文件夹中。图 9第八步：打开IAR，filenewworkspace先建一个工作空间。第九步：建立一个工程，projectcreate new project，在工程文件管理器中新建组 ，右键单击工程名addadd group，并给每个组添加相应的文件（右键单击工程名addadd file）；添加好文件的窗口如下图：图 10第10步：IAR配置，右键单击工程名opti

3、ons，跳出如下图所示窗口：图 111、 在General Options项中的 Device中选择芯片，其他项默认值OK；2、 在library configuration页中的library选择Full，否则会编译会保错，将右下角的Use CMSIS勾上。其他项保持默认值。图 123、 在C/C+ Compiler项中的Preprocessor也中添加头文件路径（$PROJ_DIR$表示工程路径，$PROJ_DIR$.是工程路径的父目录），并添加宏定义（USE_STDPERIPH_DRIVER、STM32F10X_HD），添加好的窗口见下图：图 134、 在Linker项中的cofig页中

4、Override default。如下图：图 145、 在debugger中的setup中选择自己用的仿真器。如下图：图 156、 仿真器设置页见下图：图 16到此软件配置完毕。第11步：在组App中新建app.c或者拷贝一个过来，将里面的内容全部删除，自己写。同样建立一个includes.h文件，includes.h文件下的内容图下：图 17App.c的内容可以这样写：#include <includes.h>#include <app_cfg.h>/* LOCAL DEFINES*/* LOCAL GLOBAL VARIABLES*/static OS_STK ta
