Programming ADAU1787 from MAX78000.
Dear all,
I am trying to program my ADAU1787 with program, data, register and setting which I exported from my SigmaStudio. I have two development boards, the ADAU1787 development board and the MAX78000 Feather board (which has been modified to run as a 1.8v I2C bus). To control the ADAU1787, I connected the two development boards' I2C buses, supplied it both with power and connected the grounds, thinking that is all I need. Unfortunately, it did not work.
Do you have any application note, example code that does something similar to what I am trying to do, to help me in achieving my goal?
Kindest regards

To follow on from my last message, is there any sequence of register writes that need to happen before the ADAU1787 would work properly. I have the I2C communication established and regular acknowledgments received by the micro-controller but when I simply read the vendor ID I get zeros back. What am I missing either in the Eval-ADAU1787 board, or registers that need to be set to get correct performance assuming that my starting point is applying power (or maybe reset button is pushed), what needs to happen next?
