从零搭建STM32开发环境（一）_请自己电脑安装完成stm32f10x的开发环境

最近有项目要用到STM32，感到很亲切，下面我把今天搭建keil-MDK开发环境的过程以及遇到的问题和解决方案分享出来，希望对大家有所帮助。

软件环境：keil4

硬件平台：STM32F103C8

STM32标准库版本：STM32F10x_StdPeriph_Lib_V3.5.0

步骤如下：

1、将标准库里面的CMSIS和STM32F10x_StdPeriph_Driver这两个文件夹拷贝到工程目录下。

2、打开keil4，创建新工程

   ①点击project菜单下的第一个选型，创建新工程，弹出对话框，将工程命名为key，即如下图，点击保存。

   ②接着弹出如下对话框，选择STM32F103C8。

  ③点击OK，紧接着出现如下提示：

④选择“是”。于是就会生成一个名为“startup_stm32f10x_md.s”的文件，并被组织在Source Group 1之下。到此一个工程创建完成。

3、将标准库文件导入工程中。

①点击如下图的按钮

②接着弹出如下对话框，最左边为工程目标，中间为工程的各个组，右边则为改组下面的文件，所以首先创建各个组，然后往各个组中添加文件。

添加完后如下，点击OK后工程下面就会多出CMSIS和STM32F10x_StdPeriph_Driver两项。

4、编译

①点击编译，会出现很多的错误提示：

分析：上面这些错误提示都是因为编译器找不到头文件，因此必须告诉编译器这些头文件在哪。按照如下图的①②③④步操作就可以把inc文件的路径添加进来。

②再次点击编译，会出现如下错误：

Target not created

解决这个错误的方法就是重新进入如下这个设置页面中，并在如下的Define栏中添加 STM32F10X_MD。

③再次点击编译，还会出现如下错误提示，也就是提示所有的库文件都缺失assert_param申明。

Rebuild target 'Target 1'

key.axf: Error: L6218E: Undefined symbol main (referred from rtentry2.o).

Target not created

其实，assert_param函数在文件“stm32f10x_conf.h”中，它是一个宏定义，用于对函数的输入参数进行检查。

 

在stm32f10x.h文件中搜索stm32f10x_conf.h，果然找到如下预编译代码，就是说如果定义了USE_STDPERIPH_DRIVER宏，那么stm32f10x_conf.h就包含该文件，否则不包含该文件，所以为了包含该文件，就必须定义USE_STDPERIPH_DRIVER宏。那么怎么定义呢？

有两种方法定义USE_STDPERIPH_DRIVER宏：

第一种方法就是标准宏定义：

直接在stm32f10x.h文件的起始位置定义USE_STDPERIPH_DRIVER。由于stm32f10x.h文件文件是只读属性，所以首先要把该文件修改文可读可写属性，然后通过编辑器打开，在文件头部添加代码#define USE_STDPERIPH_DRIVER。这样就算是定义了USE_STDPERIPH_DRIVER宏。

第二种方法就是偷懒的方法：

如下图所示，在下图的Define栏中添加USE_STDPERIPH_DRIVER，注意：STM32F10X_MD与USE_STDPERIPH_DRIVER之间是逗号隔开。

④再点击编译，依然提示如下错误：

Rebuild target 'Target 1'

Target not created

从提示中可以看出，目录中根本就没有stm32f10x_conf.h这个文件，把这个文件添加进去。

⑤最后编译，是不是完美通过呢？很抱歉，依然出现如下提示：

是不是快崩溃了，不过没关系，这个问题才是最后的一个问题，错误提示工程中确实了名为main的函数，那我们创建一个文件，然后创建一个main函数就可以了。

⑥创建一个名为user的组，然后创建一个名为key.c的文件，并在这个文件中定义个名为main()的函数，然后把这个文件添加到user这个组中，即如下：

再次点击编译，OK，通过！
