The routine demonstration of PC and intelligent instrument through RS485 communication interface. Instrumentation used Nissan Baxter XMA5000 intelligent expert self-tuning PID regulator, the instrument of communication protocols have been made in the routine code in detail. The routine is very simple, designed to show how VC++ Used to read and write serial port overlapping manner. This is asynchronous communication, Chuan yesterday that is synchronous communication.
