I'm currently using the BF706 Evaluation Board with the ADAU1761 Codec on it. I'm trying to take in an input sinusoid and plot the samples using CCES. Unfortunately when I try and plot the buffer (which has 64 samples), the resulting plot values don't make any sense - the plot only jumps between 0 and 2^32 (with a little bit of noise variation).
I was hoping to instead take my results directly from the ADC output, and plot those individually, but I was wondering what register the ADC outputs its values to? Otherwise, does anyone know a better method for me to obtain the input sinusoid?
I understand that this is probably a very simple question and I'd greatly appreciate any input anyone may have.
