Finally, the cue of the design for switching value input and output interface circuits was given, and then a circuit in accordance with the thought of the design produced.
最后，本文讨论了控制系统中用到的开关量的输入和输出电路的设计，并给出了具体的应用电路。
The controller main-board is designed with TMS320F2812 as its CPU, and also sets the serial interface and input and output of the switching value on it .
利用TMS320F2812作为CPU设计了控制器主板，同时引出了串口和开关量输入输出模块。
