Hello,
I am trying to transfer a project from an arduino UNO to the Feather M0
Currently I am Using:

3v 3v
3v GND GND
gnd CS ->10 rx->5
SCL->SCL DI ->11 Tx->6
SDA->SDA DO ->12
CLK -> 13

I followed the adafruit page for Transfering sketches but unfortunately I am not getting any output. Am i Missing something in the code? Or Is my pinout incorrect? I am not trying to send anything besides the hello world message yet. I just want to get the SD card recording GPS and Barometer data.
Thank you.
