Compile Error ESP32 initializing Parola with SPIclass in Arduino IDE about md_parola

[ocraml]

I cannot reproduce the issue anymore. Both, your example and my code work fine. I must have made a mistake when I tried on Friday. Sorry for bothering with it.

Function overloading is possible by changing the types or number of arguments. The new function prototype should be ok as the parameters are different.

I think you may be confusing the compiler because it is expecting a reference to an SPIClass instance, not a pointer to it. I tested the code below and it compiles with no errors.

#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include <SPI.h>

SPIClass hspi = SPIClass(HSPI);

// Hardware SPI:
#define HARDWARE_TYPE MD_MAX72XX::GENERIC_HW
#define MAX_DEVICES 1
#define CS_PIN 15

// Create a new instance of the MD_MAX72XX class:
MD_Parola myDisplay = MD_Parola(HARDWARE_TYPE, hspi, CS_PIN, MAX_DEVICES);

void setup(void)
{
  myDisplay.begin();
}

void loop(void)
{}
