Pin numbering unclear (?) - Arduino nano #23

Closed FranzSw closed 6 years ago

FranzSw commented 6 years ago

Hey,

don't know if it's just me being to stupid, but I think I can't find the right pins to connect everything. I would love a Fritzing scheme, but as long as it's not done: What pin numbering do you use?

There are these: https://www.likecircuit.com/wp-content/uploads/2017/04/arduino-nano-pinout.jpg and others: http://www.pighixxx.com/test/wp-content/uploads/2014/11/nano.png

Thanks for your help :)

It's been a very long time since I've tried the drivers on a nano, but try this:

TMC2130 Nano
SDI MOSI or D11
SDO MISO or D12
SCK SCK or D13
CS D17 / A3
EN D16 / A2
DIR D19 / A5
STEP D18 / A4

Okay, thanks, I'll try that! :)

Well the pins worked... Thanks!

Unrelated to the pins I just blew my driver when I turned up the voltage 😢
