Communicating with the CN0428 with ESP32

Hello, im doing the same and I dont understand how to start. I want to use an esp32 and wire.h Arduino library to communicate with cn0428 or Arduino interposer board. 

Do you solved this? Do you have any information about the i2c communication in cn0428?

    Hi GabrielCL,

    Would you have a block diagram or a picture of what you are trying to do?

    The CN0428 uses the ADuCM355 microcontroller, but that micro is dedicated to doing the impedance calculations and other functions dedicated to that chip itself.  That's why we are using the EVAL-ADICUP3029 board to be able to do multiple channels as well as aggregate the data into a higher level embedded application capable of representing the data and interfacing the data depending on what you are doing.

    Look forward to better understanding some of your setup specifics.
