代码是用c语言编写的，主要实现两个功能，一个是直流电机的调速，另一个是实现一个直流电压表的测量，其中用到了串行ad转换器tlc549以及da转换器tlc系列的其中还有proteus的仿真电路，可以编译后直接运行，看调试结果-Code is written in c language, the main achievement of the two functions, one is DC motor speed control, and the other is to achieve a measurement of DC voltage meter, which uses ad converter serial converter tlc tlc549 and large series
