Hi Bob! How are you? That is very nice, however, I am using ADAU1442 instead. In this case I found this citation on the tutorial:
SigmaDSPs with software readback, like the ADAU1761 and ADAU1442, have a much simpler readback operation - you just need to read the value from a certain address in memory.
And that is exactly what I am doing, just performing a read at a certain address. I also didn't find anything special about reading from ADAU1442 on the datasheet. I don't know what to do now
Kind Regards,
Fernando
