So the chips are programmed from 0-8 but the pcb is marked 1-7. Seems silly to have to ask but What's what? Is 0 on the chip 1 on the pcb? Or is 0 actually 8? Thanks. I'm an idiot. I have so many programmed chips and forgot where I put what. To test, I jumped out all pads with 50/50 resistors and will move the jumper around the program pads to confirm what I have.
