Hi all, I have a rheostat position sensor which I have is mounted on a single axis control lever. Rheostat is 2k so at center I have 1k to both extremes. I feed ADC1 on my pic this potential. I have seen on other projects like electric wheel chairs have a center tapped pot which gives an appropriate voltage ref from the center position outward which the ADC could then digitize and control various movements. I have not experimented on how the voltage ref choices on the ADC input would work to give me a relative value from the center ref voltage. Do I just set my ref pin to the center voltage and will the ADC give me a digitized value from that center voltage? I don't need to have negative values to accomplish the needed control. Any suggestions to the workings on my ADC would help. I am using a PIC24HJ128GP
