电机的转速和温度测量，很好很棒的，你可以在单片机上连好硬件电路，运行该程序来测转速-Motor speed and temperature measurements, well great, you can not even good in the single-chip hardware circuit, run the program to test speed

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

AD采集DA输出，AD位数要够高，精度才够，10位信号采集，AD140MSPS，采集速度极高，大家记得好好学习(AD acquisition of DA output, AD number is high enough, the precision is 10 AD140MSPS, signal acquisition, acquisition, high speed, Study hard to remember)
