Hello everyone;

When reading the ADC channel connected to the TP23 connector, I have difficulty understanding the incoming data. When I look at the corresponding connector output with a measuring instrument, the voltage and current variations make sense. But I cannot make sense of the ADC measurement that comes to my processor. 

  • Obviously this is erratic. Can you make sure if the SOC is setup properly, or if there are any jumper settings to be verified.

    Thank you for reply Ramesh. We were looking forward for your help.

     I think, there is nothing to do about jumper settings. Also, there is no problem in other ADC channels. 

    I see your point about SOC settings but already I am using TI default initialization routine. Is there anything I need to change in ADC init function?
