Hi there,
Good find, However the attachment is ok when going by the (iopin) for the Xiao ,The CS or SS is always the culprit.
(I always use the first 4 pins D0-D3 for stuff like that, btw)
You can clearly see the pins are 8,9,10 (SCK,MISO,MOSI)
Gpio numbers are 7,8,9
If you run the SPI_Buss software it will tell you what they are…without any defines first , then You do not even need to define them only the SS. if you get that.
