Can't get AVR library running

[goeckeritz]

Hey guys,

I have a TMC222 and a AVR ATMega328P wired up for I²C connection. I can't get the communication running using the Trinamic provided AVR C library. All I get is strange stuff, see attachment, please.
Does anybody have a hint, on how to get it running? I don't want to rewrite tha half lib just for using another TWI lib.

thanks!

regards from Germany.

Hey guys,

just got it up and running. I had a wrong wiring, actually. Library works just fine...I updated the interrupt routine though.
Replaced outdated

Code: Select all

SIGNAL(SIG_2WIRE_SERIAL)

with newer

Code: Select all

ISR(TWI_vect)

Works fine, thanks for that!

Now I am about to find the right copmbination of commands to get my stepper turning...

Cheers
