It seems that God is not without a sense of humor...
So, I had a bit of a run there for a while of producing boards which later became coasters. Bound and determined to not let that happen again, I set out to design my WiiCamera break out boards. I carefully layed out the circuit, breadboarded each and every part, and then designed a neat, simple PCB around the breadboard circuit.
The boards came in today, and I happily soldered one together using the crystal I had used during the mock-up. How pleased I was when it worked perfectly. I proceded to solder the other 5 units together and moved on to testing. Oh, how my spirit sunk as each one failed to spit out even one single byte of data...
In the end, it seems, the crystal I had done the mock-up with does not share a pin-out with the 20-or-so crystals I had bought to use during production --2 pins (gnd and output) are reversed. Or rather, those 2 pins are reversed on the one I used in the beginning. Thank God, I only ordered 6 boards and with new boards, the crystals I have on hand will work just fine. I have already done the fix, and sent off the Gerbers, but alas, I am now back to my usual routine of mailbox watching...
Uff-da.
