描述

（3）在工程文件夹中创建四个子文件夹，HEADERWARE，OBJECT，USER和SYSTEM，各文件夹内容如下所示。

USER：存放工程文件，汇编启动文件与主函数的c文件

SYSTEM：存放系统文件，串口1文件和滴答时钟文件

HEADERWARE：存放其他的驱动文件

OBJECT：存放编译过程的链接文件以及最终的HEX文件

ARM

（4）新建工程，输入工程保存路径后点击保存。

ARM

ARM

（5）选择目标芯片型号，我们使用的芯片型号是STM32F103ZET6

ARM

ARM

ARM

（6）点击工程设置，添加系统文件夹

ARM

点击红框选中的位置来新建文件夹，双击新建的文件夹修改名称，创建和步骤3目录一样的文件夹，如下图所示。

ARM

（7）创建启动汇编文件

ARM

点击保存，输入文件名stm32f103x.s后保存进User文件夹。

ARM

输入以下代码，由于以下代码是固定的，所以可以直接复制

（8）修改链接文件与HEX文件的保存路径

ARM

修改HEX的保存路径

ARM

修改链接文件的保存路径

ARM

（9）创建主函数的c文件，创建步骤与步骤7一样，只不过保存的时候，文件后缀变为c，例如1.c。将主函数的c文件保存到User目录下

ARM

（10）在c文件下输入如下代码

#include 
int main()
{
  while( 1 )
  {

  }
}

（11）将刚才创建的2个文件添加进工程

ARM
