些源码是一个高精度直流测试校准源码，采用串口通信可以用来调试和测试表-some source is a high-precision calibration source DC tests, using serial communications can be used to debug and test table

实现对直流电机的PID控制，其中包含直流电机的动力学模型，控制律的设计方法-DC motor PID control, which contains a dynamic model of the DC motor control law design method

由LM14203设计的直流电源，输入电压为3V,输出电压为10V-it is a DC source designed with LM14203. The output voltage is 10 and the input is 3V.
