Time to downsize...

uDSP and uCODEC above.

Both power up without smoke.

uDSP talks to SigmaStudio, I have fitted an ADAU1450, but the crossover program for my ADAU1452 loaded onto it (I assume the unused registers are just ignored), it was putting out the expected clocks. It's missing the EEPROM - ordered from both Digikey and Farnell and forgot to get a SOIC-8 EEPROM. 

Need to test uCODEC with clocks. But I need to get some tall 2.54mm headers, then I can stack them as intended.
