使用protues软件搭建简易LED灯循环控制系统；其中用到了网络标记的方法连接电路。
并使用了keil软件编写驱动程序，并生成了hex文件，写入单片机；
电路调试成功，8只LED灯循环闪烁。(Protues software is used to build a simple LED lamp cycle control system, which uses the method of network marking to connect the circuit.
The keil software is used to write the driver, and the hex file is generated and written to the single chip computer.
The circuit debug successfully, 8 LED lights cycle flicker.)
