南音酱的一己之见 | 人傻不能怨社会论如何在arduino pro mini 上制作一个倒计时[使用TM1637]. Include “TM1637.h”. Int8 t TimeDisp[] = {0x00, 0x00, 0x00, 0x00};. Unsigned char ClockPoint = 1;. Unsigned char Update;. Unsigned char halfsecond = 0;. Unsigned char second = 60;. Unsigned char minute = 3;. Unsigned char hour = 0;. Define CLK 3/ pins definitions for TM1637 and can be changed to other ports. TM1637 tm1637(CLK, DIO);. Timer1.initialize(500000);/ timing for 500ms. Timer1.attachInterrupt(TimingISR);/ declare the interrupt serve routine:TimingISR.
