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

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)
