BTT TMC2240 does not use diag1 #86

TMC2240__08 Screenshot_20231104_202058_Drive According to BTT website. The tmc 2240 uses diag0 not diag1

Also for the Octopus Pro, it's seems diag0 is associated with motor0 and diag1 is associated with motor1.

I think there needs to be better clarification on how to configure the proper pin outs

Edit: so the diag numbering on the board is for assigning to each motor slot and the diag number is that one used by the driver. It's only for selecting the proper pin out for that motor

I just measured the pins on my BTT TMC2240 stepsticks and the diag pin is indeed wired to the diag0 pin on the TMC chip.
