Most TM1637 libraries support displays with 4 digits. I picked up several 6 digit displays that use the TM1637 chip and wanted to get it to work (made by diymore). The TM1637 drives up to six 7-segment LEDs so I expected it to be straight forward. However, the way the 6-digit display modules are built, the two blocks of 3-digits were in reverse order (would display 321654 using standard TM1637 libraries to drive it).
I updated the TM1637TinyDisplay library to now also support 6 digit displays. I added the map and reversed the serial upload sequence to get it to work (now showing 123456). I would like to know if anyone discovers any 6-digit displays based on the TM1637 that do not work with the following code.
Install TM1637TinyDisplay via Arduino IDE.
// Includes
#include <Arduino.h>
#include <TM1637TinyDisplay6.h> // Include 6-Digit Display Class Header
// Define Digital Pins
#define CLK 1
#define DIO 2
TM1637TinyDisplay6 display(CLK, DIO); // 6-Digit Display Class
void setup()
{
display.setBrightness(BRIGHT_HIGH);
display.clear();
display.showString("digits");
delay(1000);
display.showNumber(123456);
delay(1000);
display.showNumber(123.456);
delay(1000);
}
