This was a module based on the TM1638 IC that I purchased.
TM1638
The imprtant connections are as follows
data pin 3
clock pin 2
strobe pin 5
I decided to create an example that would display the button pressed on the display, you will need the library below
The library is https://github.com/Leonardoventurin/tm1638-library
Code
#include <TM1638.h>
#include <TM1638QYF.h>
TM1638QYF module(3, 2, 5);
word mode;
void setup()
{
module.setupDisplay(true, 7);
mode = 0;
}
void update(TM1638QYF* module, word* mode) {
word buttons = module->getButtons();
// button pressed - change mode
if (buttons != 0) {
*mode = buttons >> 1;
if (*mode < 128) {
module->clearDisplay();
delay(100);
}
}
switch (*mode) {
case 0:
module->setDisplayToString("press 1");
break;
case 1:
module->setDisplayToString("press 2");
break;
case 2:
module->setDisplayToString("press 3");
break;
case 4:
module->setDisplayToString("press 4");
break;
case 8:
module->setDisplayToString("press 5");
break;
case 16:
module->setDisplayToString("press 6");
break;
case 32:
module->setDisplayToString("press 7");
break;
case 64:
module->setDisplayToString("press 8");
break;
case 128:
module->setDisplayToString("press 9");
break;
case 256:
module->setDisplayToString("press 10");
break;
case 512:
module->setDisplayToString("press 11");
break;
case 1024:
module->setDisplayToString("press 12");
break;
case 2048:
module->setDisplayToString("press 13");
break;
case 4096:
module->setDisplayToString("press 14");
break;
case 8192:
module->setDisplayToString("press 15");
break;
case 16384:
module->setDisplayToString("press 16");
break;
default:
module->setDisplayToString("?????");
break;
}
}
void loop()
{
update(&module, &mode);
}
