Feather M4 Express Pin number/names?

Post by darylthunter »

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!

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.
