    Help with using ADC to LCD to measure a sine wave

       Hi, Can anyone help ?


      I'm just trying to use the LCD to display voltage of the sinewave but so far i'm not getting any luck.


      I'm feeding an a sine wave with from a function generator to ADC and display it on the LCD display.


      I brought out AGND to en external pin to move the reference to Vdda/2.


      It is able to read the dc values not ac values. HELP ??? I want to be able to read the value of a sine wave . Peak to peak or RMS.
