摘要
介绍了一种基于PXA255的应用于嵌入式工业控制中异步串口的扩展和在WinCE下的实现。简要介绍PXA255串行通信口和TL16C554异步通信芯片。详细给出一种采用TL16C554来扩展串口的设计实现方案,同时给出相关原理图和在WinCE下的实现方法。
This paper describes the design of an asynchronous serial port expanded in embedded industrial control based on PXA255 processor under WinCE.It briefly introduces the serial port PXA255 and the asynchronous communication chip TL16C554.It gives a detailed design method by using TL16C554 to expand serial port,and gives the main schematic diagram and the realization under WinCE.
