摘要
现代工控技术对时间的要求很高,一些实时的测量监控系统使用实时时钟芯片,但是这样做精度不高,而且软件相对复杂。本文介绍了如何利用串口扩充来实现GPS和ADSP21XX之间通讯。先对GPS做了简要的介绍,而后给出了GPS和DSP通讯的具体实现方法,最后给出了样图和相关程序。
Modern industry control technology requires high precision of clock, some real time measurement & control systems use real - time clock IC, but in this way we cannot get the precise time and also make the software more complex. This paper introduces the implementation of communication between GPS and ADSP21XX by expanding Serial Ports.
