 I swapped the chips from the 3rd board and the 5th (from left to right) and now it seems to work. I have no idea why? If I swap them back I get the same problem. I guess I will just leave them in the way they work, and not worry about WHY? (If I can sleep not knowing)

Ok….. I cut all of the scanners apart, and looped the in’s and out’s. They each work fine by themselves. So I’ve rewired them all together, and now when I start them, the “pulse” starts a the 1st board from the left, and the 3rd board simultaneously. the pulse then run through the second board and stops. The 3rd board runs as if it was wired as a single board.I tried to insert a pic, but apparently I can’t. I am at a loss.

I followed the articles directions step by step, and it is certainly possible that I’ve made a mistake, but I’ve checked and re-check and I don’t see any wiring mistakes.

i Purchased 5 preprogrammed ATtiny2313 for Larson scanner-extended chips. Is there an “Easy” way to determine which firmware is on each chip? I have a USBTnyISP AVR PRogrammer, I’m just not very proficient with it. I’m also not sure what board build up you are referring to.
