I'm trying to convert an Arduino sketch for controlling an ADF4351 PLL board that was written for a different Arduino board for use with my Feather M4 Express board.
The ADF4351 board uses SPI to communicate and the pin names/numbers are different from what I am seeing for the Feather M4 Express. Is there a board definition file some where in the IDE that tells me which pins are assigned as what?
Thanks!

Re: Feather M4 Express Pin number/names?
What are the pins named on your ADF4351 board?
The main SPI pins on the Feather are SCK (clock), MO/MOSI (data from the MCU to the PLL), and MI/MISO (data from the PLL to the MCU). You'll also need a CS (chip select).

Thanks,
I was also able to find what I was looking for in the Library\Arudino15\packages\adafruit\hardware\samd\... path and looking in the right subfolder for the board.
