文字代码

#include “TM1637.h”

#define CLK 2

//pins definitions for TM1637 and can be changed to other ports

#define DIO 3

TM1637 tm1637(CLK,DIO);

void setup() {

// put your setup code here, to run once:

tm1637.init();

tm1637.set(BRIGHT_TYPICAL);

//BRIGHT_TYPICAL = 2,BRIGHT_DARKEST = 0,BRIGHTEST = 7;

}

void loop() {

// put your main code here, to run repeatedly:

int8_t NumTab[] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};

//0~9,A,b,C,d,E,F

tm1637.point(true);//显示中间的分号

tm1637.display(0,NumTab[1]);//控制每一位数码管的显示

tm1637.display(1,NumTab[2]);

tm1637.display(2,NumTab[3]);

tm1637.display(3,NumTab[4]);
