Hi Team,

My customer find that the ADC_12 channel of MSPM0G3507 PA14 PIN cannot be configured to sample. But other channel can. What is the reason?

Thanks & Regards

    Hi Yale,

    I took the example code adc12_single_conversion_LP_MSPM0G3507 and, in Sysconfig, changed the the ADC Conversion Memory 0 configuration input channel to channel 12 (PA14).

    I then ran the example code and was able to get the ADC reading on PA14. Can you describe more of the customer's scenario? or maybe share their CCS Project?

    Regards,
    Luke

    Hi Luke，

    I used the MSPM0G1107 configuration to run on MSPM0G3507. When the MSPM0G1107 18PIN is configured as the ADC sample, the MSPM0G1107 18PIN should be green, but the MSPM0G1107 18PIN is still gray. ，Please help to see how to set it?

    Hi Switch,

    This is a visual bug, the device still gets configured to use PA14 as the ADC input channel so functionality of the ADC will work properly. The bug is documented and in the plans to be fixed.

    Regards,

    Luke
