Hardware and Software Design between Microcontroller and Computer Based on USB Interface

摘要

This paper studies how to use the USB interface to achieve communication between Sun plus 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.
