LTC2497 Conversion


I am using LTC2497. I am trying to get the ADC conversion reading, could anyone explain how does the conversion of 2's compliment to decimal works on this ADC? I tried many times and it does not seem to be working.

Thank you.

  • Hi ghoover

    This is the scope photo. What I coded,

    1. For loop to increment the channel address

    2. Write I2C addres

    3. Write channel address

    4. Read data

    5. loop back to step 1

    This is where the problem lies, the code runs for 1 cycle and keep repeating the same channel address without increment...On the serial monitor, i did a printout to check, the channel address is increasing but the scope is not showing it / ADC not responding to the change in channel address...
