/* Example code for TM1637 4 digit 7 segment display with Arduino. More info: www.makerguides.com */
// Include the library:
#include <TM1637Display.h>
// Define the connections pins:
#define CLK 2
#define DIO 3
// Create display object of type TM1637Display:
TM1637Display display = TM1637Display(CLK, DIO);
// Create array that turns all segments on:
const uint8_t data[] = {0xff, 0xff, 0xff, 0xff};
// Create array that turns all segments off:
const uint8_t blank[] = {0x00, 0x00, 0x00, 0x00};
// You can set the individual segments per digit to spell words or create other symbols:
const uint8_t done[] = {
SEG_B | SEG_C | SEG_D | SEG_E | SEG_G, // d
SEG_A | SEG_B | SEG_C | SEG_D | SEG_E | SEG_F, // O
SEG_C | SEG_E | SEG_G, // n
SEG_A | SEG_D | SEG_E | SEG_F | SEG_G // E
};
// Create degree Celsius symbol:
const uint8_t celsius[] = {
SEG_A | SEG_B | SEG_F | SEG_G, // Circle
SEG_A | SEG_D | SEG_E | SEG_F // C
};
