Hi there,
No Problem, I don’t have that MCU or I could help better , But you are close.
My example wasn’t the correct syntax for your scenario,
So
Here is what it should be:

// Map SPI port to 'new' pins
#define SS 28
#define MOSI 3
#define MISO 4
#define SCK 2
Serial.println("--------------");
  Serial.println(SS);
  Serial.println(MOSI); // master out, slave in
  Serial.println(MISO); // master in, slave out
  Serial.println(SCK);  // clock
  Serial.println("--------------");

Try that and LMK

can you post the whole code your using (with these edits)and also the last 20 or so lines of compiler output?

At least you confirm it’s using the PORT numbers for pins. that’s progress, LOL
the NOT pinned out info is when they are NOT defined in the pins file.
