通过stm8的定时器进行计时，将数据存储到EEprom里面，通过定时器进行按键检测(Timer through the stm8 timer, the data stored in the EEprom, through the timer button detection)

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)
