摘要
研究了如何利用USB接口实现凌阳61a单片机与普通个人计算机之间的通信系统的设计。整个系统设计中包括电路设计、协议研究、上位机程序设计、下位机程序设计以及驱动程序设计5个方面的内容,所有的程序采用C++语言编写。通过在单片机与计算机之间进行简单的字符信号传递,测试了两者之间利用USB协议传输信息的正确性。
This paper studies how to use the USB interface to achieve communication between Sunplus 61A MCU and ordinary personal computer.The design of the entire system has 5 aspects,including circuit design,protocol,host computer programming design,and lower computer program and driver.All the program is written using C＋＋.Simple character signal transmission between microcontroller and computer is done.Information can be transmitted successfully using USB protocol.
