本文描述了如何利用简单的硬件连接实现DSP的同步串行口与PC机的异步通讯。
This paper describes how to actualize the asynchronous communication between synchronous serial port of DSP and asynchronous serial port of PC by simply hardware connection.
串行口对时方式:装置通过串行口读取同步时钟每秒一次的串行输出的时间信息对时,串行口又分为rs232接口和RS422接口方式。
Mode of serial port pair: synchronous clock device through the serial port read per second pair a serial output time information, serial port and RS232 interface and RS422 interface.
