Great help thanks - I already feel very optimistic about this and think I will stick with the ADAU1452 in the promise of what is to come in the future.
This leads me to the next question, how do I control the Volume Control from logic control outside the ADAU1452 part. I found some toggle up and down, but if I need to set a value for volume level directly - then how do I do? I'm thinking 3-wire type chipselect, clock and data to keep down pin count. Can I do a register structure with several adresses? One interface to do all my settings.
Best regards,
Thomas
