Internet Based Clock using ESP32 and MAX7219 Dot …

WebThe MAX7219 communicates to microcontrollers via SPI. The ESP32 has three (usable) SPI ports but somehow, the LEDMatrixDriver library defaults to SPI3. Hence, the SDO and SCK pins are GPIO23 and GPIO18 respectively. However, the CS pin is not the default pin since the library requires you to declare it (GPIO15 in this project). Web App WebFirst of all we will obviously need an ESP32, but also a MAX7219, remember that the MAX7219 is only a controller to be able to modify 8 LEDs as we want, but nothing prevents us from assembling 4 of these MAX7219 and controlling one total of 32 independent LEDs.
