abaskin / max72xx Goto Github PK

I am currently trying to use this lib on nano ESP32 as it says its supporting ESP32.

As the specified ESP Pinout is not working on nano I tried using the SPI interface which is on the same pins as for the other boards like uno.

I used this as a test code:

`#include <Arduino.h>
#include <MAX72XX.h>

constexpr uint8_t latchPin = 7; // change to reflect your latchPin
constexpr uint8_t numDevices = 1; // the number of devices

// for hardware SPI
// create the object for the device chain
MAX72XX dispChain(latchPin, numDevices);

// create the time displays
MAX72XXDisplay counterDisp(&dispChain, 0, 5);
MAX72XXDisplay txtDisp(&dispChain, 5, 3);

void setup() {

dispChain.setIntensity(10); // set the intensity for all the devices

counterDisp.writeNumber(921, 1);
counterDisp.update(true);
txtDisp.writeChar(0, MAX72XX::Character::BLANK);
txtDisp.writeChar(1, MAX72XX::Character::P);
txtDisp.writeChar(2, 0b00111110 );
txtDisp.update(true);
}

void loop() {
}`

When testing with uno it works perfectly fine.

When testing with nano ESP the display stays off..

Am I doing anything wrong or will the library just not work with the nano?
