摘要
以Silicon Laboratorcs公司的C8051F020为系统单片机,并以CH372作为USB接口芯片,进行USB传输;同时利用CPLD实现地址译码与读写控制,从而可根据需要扩展外围功能模块,不仅方便电路的改进,同时达到了很好的传输效果,充分发挥了USB高速传输的特点。
This paper proposes a method that based on C8051F020 and CH372 to carry on data transmission.Meanwhile it can expands peripheral function modules according to need by CPLD which can be used for address decoding and read/write controll.This method has proved to be of good transmition effect and entirely showed the high-speed feature of USB transmission.
