    Measuring VDDA with Capsense ADC

    PaGy_1246781

      Hello All,

       

      I would like to measure the voltage at pin VDDA.  On page 18 of the CY8C63x6/7 data sheet it states that the Capsense ADC can measure VDDA against an internal reference without using GPIO or external components.  However, I can find no information about actually doing this.

       

      I've studied the documentation for the CSDADC middleware library.  I see how to connect the ADC to GPIO pins, but I can't figure out how to connect to VDDA.  Does anyone know how?
