程式範例
#include “TM1637.h”
#define CLK 3//pins definitions for TM1637 and can be changed to other ports
#define DIO 2
TM1637 tm1637(CLK,DIO);
void setup()
{
tm1637.init();
tm1637.set(BRIGHT_TYPICAL);//BRIGHT_TYPICAL = 2,BRIGHT_DARKEST = 0,BRIGHTEST = 7;
}
void loop()
{
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
int8_t ListDisp[4];
unsigned char i = 0;
unsigned char count = 0;
delay(150);
while(1)
{
i = count;
count ++;
if(count == sizeof(NumTab)) count = 0;
for(unsigned char BitSelect = 0;BitSelect < 4;BitSelect ++)
{
ListDisp[BitSelect] = NumTab[i];
i ++;
if(i == sizeof(NumTab)) i = 0;
}
tm1637.display(0,ListDisp[0]);
tm1637.display(1,ListDisp[1]);
tm1637.display(2,ListDisp[2]);
tm1637.display(3,ListDisp[3]);
delay(300);
}
}
接線範例
接線方式如果配合S4A Sensor Board只要把電話接頭(RJ11)接到標示D3D2孔位即可完成連接。注意 CLK及DIO 的設定腳位!
