RVMDK建立STM32工程

2010-11-23 11:05 176 查看
网上搜到很多这样的帖子,但只说到建立起一个工程,没说到怎么做出一个可以软件仿真调试的小程序;或者给了段程序代码,没说到怎么配置其他的库。我自己在RVMDK里编译的时候总是报各种各样的链接错误,摸不着头脑。摸索了一阵搞定了,步骤记录如下。

1. 在工程文件夹下添加"src", "lib", "obj", "list"子文件夹.

2. [project]----[new uVision project]---选择STM32F107VC---[ok]----[yes]

3. [Setup file extensions, books and environment] / [poject---manage---commponents, environment, books...]-----[poject commonents]----- change name in [project Targets]-----change to "startup", add "src","lib" in [groups] ----- [ok]

4. [options for target] ----- [output] ----- [select folder for objects] ----- 选为建立的obj子文件夹 ----- [listing] ----- [select folder for listings] ----- 选为建立的list文件夹 ----- [debug] ----- [use simulator] ----- [ok]

5. 找到keil安装目录下的stm32f10x_rcc.c,以及工程中需要用到的其他外设的C文件,拷贝到工程中lib文件夹下。新建main.c到工程文件夹的src文件夹下。我找的一个小例子用到了rcc, gpio和flash,于是把这三个.c拷贝到lib文件夹中。按照步骤3,把文件添加到RVMDK工程中。

6. 在main.c中添加#include "stm32f10x_lib.h"。添加代码。按F7编译。我用的代码是从网上搜的一个类似于跑马灯的小程序,将贴在本文最后。编译过后,每个文件需要链接的头文件会自动添加在该文件的下面。

7. ctrl+F5进入调试,F5至可运行。[peripherals] ----- [General purpose IO] ----- [GPIOB]。可以看到跑马灯的效果。ctrl+F5结束调试。

这个程序是可以跑通了,但是我有点怀疑这个步骤的正确性。按照视频教程的说法,如果做应用程序,需要修改的只有main.c, stm32f10x_conf.h, stm32f10x_it.c。但是上述步骤只有在编译完成之后才会链接到keil安装目录下的conf.g,没有自动链接it.c。而如果不先在conf.h里配置正确的外设,RVMDK是编译不过的。可能在实际工程中这两个文件也需要事先手动添加修改。

视频教程里有一张library的结构图,截不下来,就把其中几个文件的功能罗列如下。

stm32f10x_it.c: 中断处理函数

stm32f10x_lib.c: debug时指向外设结构体的指针

stm32f10x_lib.h: 全局头文件、变量

stm32f10x_map.h: 外设结构体,地址

stm32f10x_type.h: 公用类型、常量

stm32f10x_rcc.h: 时钟,复位外设,用外设时都要用到。
