    Arun

    Can you elaborate on " cannon communicate properly" . Can you capture the data on the comm lines with a scope so we see the signals clearly to ensure you aren't violating any of the i2c requirements?

    thanks

    Hi Arun,

    Thank you for the videos - could you please modify your timescale and take a snapshot of communication with both the clock and data on channels 1 and 2, respectively?

    Sincerely,
    Bryan Kahler
