How do you deal with the frustration of prototyping a circuit, only to find that it doesn't work as you expected it to?
I'm prototyping a circuit for the Renesas RX Design Contest that uses the Texas Instruments PCM3060 audio CODEC. I'm basically copying someone else's schematic. And I can't get it to work as expected. I'm feeding the CODEC a clock signal but it's not giving me any data from the ADC. I etched two circuit boards and both have the same behavior. I don't know what the problem is. Did I wire it wrong? Did I damage the chips? I don't know.
Very frustrating. Very demoralizing. In times like this I think of all the time and effort I put into a design and prototype, and the frustration that it gets me, and wonder why I do it.
Hopefully I'll get an answer to the question I posted on TI's forums about this problem. I don't know how to make any progress from where I am now.
