分享自己参加电子产品设计时的任务和相应的程序，有些程序是自己独立完成的，难免有些不足。话不多说我就将文件分享给大家了。

电子产品设计与制作集训任务单

日期：2018年4月1日

主题：
1.STM32 系统板原理图设计与绘制;
2.STM32 系统板调试方法;
3.STM32 系统板初始化程序设计与调试。

任务：
1. 绘制STM32F103原理图；
2. 熟悉JLINK使用，能使用JLINK烧写STM32程序；
3. 使用STM32CubeMX生成主频72MHz，及LED、按键对应的GPIO初始化代码；
4. 在生成代码的基础上，完成LED、按键部分代码的编写。要求如下：

a) S1按下LED1亮，松开后LED1灭；

b) 按下S2，LED2亮，松开后LED2不灭；再次按S2，LED2灭。如此反复；

c) S3、S4需同时按下（不区分先后，可以先按下一个再按另一个），LED3亮，松开任意一个按键，LED3灭。

单片机源程序如下:
