Description

Code worked when Platformio Development environment is set to [env:esp32dev] but when changed to [env:wt32-eth01]
code fails with:

platformio/packages/framework-arduinoespressif32/libraries/SPI/src/SPI.cpp: In member function 'void SPIClass::begin(int8_t, int8_t, int8_t, int8_t)':
/.platformio/packages/framework-arduinoespressif32/libraries/SPI/src/SPI.cpp:64:37: error: 'SCK' was not declared in this scope
_sck = (_spi_num == VSPI) ? SCK : 14;

It appears that the:
espressif/arduino-esp32/blob/master/variants/wt32-eth01/pins_arduino.h

Does not contain the same elements as the other library:
static const uint8_t SS = 5;
static const uint8_t MOSI = 23;
static const uint8_t MISO = 19;
static const uint8_t SCK = 18;

Sketch

#include <Arduino.h>
#include <SPI.h>

#define VSPI_MISO -1
#define VSPI_CS 12
#define VSPI_SCLK 14
#define VSPI_MOSI 15

SPIClass *vspi = NULL;

void setup(){
  vspi = new SPIClass(VSPI);                              //create spi
  vspi->begin(VSPI_SCLK, VSPI_MISO, VSPI_MOSI, VSPI_CS);  //SCLK, MISO, MOSI, SS
  pinMode(VSPI_CS, OUTPUT);                               //VSPI SS
  digitalWrite(VSPI_CS, HIGH);                            //pull ss high t 
}

void loop()
{
  delay(1);
}

@P-R-O-C-H-Y - I think that this is a case simillar to #6737

Actually, it lacks SPI pin definition in pins_arduino.h for wt32-eth01 board.
But we should think about a schema similar to HardwareSerial, where we check if RX1, TX1 are defined in pins_arduino.h, otherwise it just uses some default definition.

@wmarchewka The author of the board doesn't declare the default SPI pins. Adding the same pins as default ones for ESP32 to the pins_arduino.h can conflict with Ethernet pins.
