摘要
工业领域串口通信速度慢是个比较突出的问题,而FT245BM能够进行USB和并行I/O口之间的协议转换,在一些条件下能够取代串口.介绍FT245BM芯片的工作原理和功能,并给出基于FT245BM的USB接口电路的应用设计和基于89c52的汇编及c51单片机源程序.
The poor performance of serial communication has been an issue in the industry for a while,and FT245BM chip can exchange the protocols between USB ports and parallel ports. This papers introduces the basic principles and functions of the FT245BM chip, and also presents the application design based on FT245BM interface circuit, the assembler based on 89C52, and the source code of c51 single chip micro- processor.
