Design of USB Communication System Based on C8051F340 MCU

摘要

This article, taking computer as USB (Universal Serial Bus) Host and C8051F340 MCU (Micro Control Unit) from Silicon Laboratories as USB Device Controller, has designed a USB Smallest Communication System. With the help of USB driver source code provided by Windows DDK (Device Development Kit), the system can realize the USB communication function between MCU and computer. The article describes the smallest unit design of USB firmware as well as simple USB application development in detail.
