ARM开发环境入门

一、安装mdk5软件和stm32包二、stm32程序——闪烁LED 1.先建立工程选择需要的芯片并进行相关设置 2.编写程序代码

三、Proteus 电路仿真软件

1.将本次仿真需要的软件添加到元件列表中：AT89C51、电阻、数码管、开关、喇叭等等，如下图所示 2.仿真单击开始仿真。 3.源代码调试双击Keil uvision图标，进入KeilC Vision集成开发环境，创建一个新项目（Project），并为该项目选定合适的单片机CPU器件（如：Atmel公司的AT89C51）。并为该项目加入Keil C51或ASM51源程序。源程序代码如下：

4.单击“Project菜单/Options for Target”选项或者点击工具栏的“option for target”按钮，弹出窗口，点击Output将Create HEX File打勾 5.KeilC与Proteus连接仿真调试点击仿真后，得到如下图的结果：随着仿真的运行，能听到喇叭的声音，也能看到显示屏的数字，就算仿真成功了。
