I am using an Argon with the Ethernet FeatherWing and I would just like to confirm which pins I cannot use in my firmware. According to the Accessories page, the Ethernet FeatherWing connects to the following pins on Gen3 devices.
MISO → SPI MISO
MOSI → SPI MOSI
SCK → SPI SCK
D3 → nRESET
D4 → nINTERRUPT
D5 → nCHIP SELECT
So, I get that I cannot use D3, D4, and D5 in my firmware.
What about MISO, MOSI, and SCK? Are these corresponding to D11, D12, and D13? Does it mean that I cannot use D11, D12, and D13 as I/O pins?
Thanks for any quick help!
