通过定时器定时进行时间显示。使用AD功能读取采样电阻的电流值，与设定值比较控制MOS管的开关(Timing display by timer. Using AD function to read the current value of the sampling resistor, and compare with the set value to control the switch of the MOS tube)

STM8 AD采样 读取，串口发送实例，通过初始化ADC的AIN10通道，将传感器的ADC值通过串口进行打印(STM8 AD sample read, serial send instance, through the initialization of the AIN10 ADC channel, the sensor ADC value through the serial port for printing)
