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Windows CE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Windows CE下的实现方法。
In this paper a design of asynchronous serial - port expanded in embeded industrial control using PXA255 processor and Windows CE is presented. It presents the serial - port of PXA255 and asynchronous communication chip TL16C554. It gives a detailed design method using TL16C554 to expand serial- port. Also it gives the main schematic diagram and the realization on Windows CE.
