| Oct 13, 2017 at 19:51 | comment | added | electrophile | This is very interesting. If my data direction were to be from An to Bn, then I'll have to connect my Atmega's pins to An and then the external driver logic inputs go to Bn and then Bn pins also go to the motor driver. I'm getting it right? | |
