摘要: 介绍了双路异步串行通信谐波监测系统的构成。利用PC16552设计了一种TMS320C32和上位PC机之间通信的新型接口电路,并且采用可编程逻辑器件CPLD控制PC16552的接收/发送信号。实践证明该接口电路能够有效而快速地传输数据。Abstract: The paper introduced the structure of harmonic measurement system of two-way asynchronous serial communication. A new-style interface circuit was designed with PC 16552 chip between TMS320C32 and PC. And CPLD controls receive/send signal of PC16552. It is shown that the interface can transmit data effectively and rapidly.
