    Thread Summary
    
                The user experienced unreliable communication with the AD5245, potentially due to pull-up resistor issues. The final solution involved changing the pull-up resistor from 10kΩ to 2.2kΩ, which improved the communication. The user also noted that the issue was resolved when connecting an oscilloscope, suggesting a possible edge detection problem.

    The communication with the AD5245 is sometimes not successful. It may be a pull-up problem. Can you tell me which values are good for the pull-up for this device. I am using 10k resistors for the pull up.
