Hi. When I use PIC18F I usually use a 10k pot when I want to read a pot value. But now I am using a dspic33f microcontroller and the input impedance is much smaller - 2.5kOhms is maximum recommended for PIC18F, but for the dspic the maximum is only 200ohms! (To minimize the effects of pin leakage currents, it says). I have 6 pots Id like to read, but don't want to consume too much current. Has anyone got any recommendations?
Oh and does it matter if I connect the pot ends to the PIC power supply or the AVdd/AVss pins?
Thanks
