基于W77E58双串口通信的数据收发系统

The Design of Data Send and Receive System Based on W77E58 with Two Serial Port

介绍了利用激光测距仪提供的RS232串口和W77E58单片机之间的串口,设计出串口通信电路系统。给出了串口的通信协议与控制指令,并借助于串口调试软件进行了调试,能实时将激光测距仪测得的数据发送给视频叠加模块,送入显示终端,将距离数据显示在视频图像上。

RS-232 Serial port was used to communicate with laser range finder between W77E58 single chip; a serial communication circuit system was designed. The serial port correspondence agreement and control instruction were given, the serial port debug software was used to debug serial port , the data sent by Laser Range Finder is processed by video superposition module on real-time and sent to terminal display from the data displayed on the video image.
