I'll try to get to this sometime this week
 

So, did you create firmware for this setup? I am using this BoB´s in several machines, I would like to switch to driving them by 7i92, but cant find proper pinout in 7i92 firmwares file downloaded from your pages. Or whats the name of file with this pin setup?
