SAMD21 Pro RF and Ethernet

Development Boards
1

I would like to connect a W5500 ethernet module to my SAMD21 PRO RF using the header pins on J11 labeled MISO, MOSI , SCK and a CS and RST that would work.

Do those pins go to pins 19(MOSI), 20(SCK) and 21(MISO) on the SAMD21 chip and does the board definition support them?

What pins should I use for CS and RST?

In the Arduino IDE, how do I call them out ( <Ethernet2.h>, <SPI.h> ) to get the correct pins?

Any help would be greatly appreciated .

Thanks

Hi JCH.

MOSI, MISO, and SCK do connect to pins 19-20 on the chip and are enabled. CS and RST for your device connect to whatever pins you want to use in your code and aren’t limited to any specific pin on the Pro RF board. Sadly I do not have any hookup information for the W5500 and you’d need to contact whoever makes that for code assistance in getting it working.
