Ambika Voicecard Issue(s)

#1

OK… I’m stumped…

  1. One of my voice cards is not working (I don’t think it ever has). The Data LED does not light up, no matter which port I mount it. Furthermore, swapping the ATMEGA with a known working one doesn’t resolve it, suggesting a board issue. I’ve checked power to the IC, and continuity to the crystal, capacitor values etc. and that all works. I think the only other thing I can do is swap out the crystal?

  2. As a seemingly separate issue I discovered while troubleshooting, when I put a known working board in the #6 port, the data light only briefly flashes on boot, and then goes dark. When I go to the “About” page and scroll to port 6, the DATA LED starts flashing. What’s up with that?

Any help is appreciated!

Confirmed… it was a bad crystal… (never had that happen!)

Issue 2 was apparently a user error. It seems the data led doesn’t light up when the card isn’t assigned to a voice.
