Am I right in thinking that the J14 jumper is only there to swap the analogue/digital inputs of RA0-3? And therefore if I use RA4 i do not need to alter any jumpers, just ensure that RA4 is set as an analogue input in the registers of my pic?

Thanks again for the help!!

I have just been trying another method: I am using the VREF+/- from the ZigBee IC. Basically, I am using the ZigBee Vcc as VREF+ and its GND as VREF- ...is this correct? To do this i have my ADCON1 register set to 0x08; and ADCON0 to 0x89; ZigBee Vcc is connected to RA3 (VREF+) ZigBee GND is connect...

Hi, im wondering if you can help me again please. I'm now trying to further the design here in this thread. I wish to implement an external analogue input (the RSSI pin of a ZigBee module), rather than the onboard potentiometer. I'm struggling to get all the inputs, outputs and registers set up corr...

Thanks so much for the reply Benj, exactly what i was after! I now have RV3 turning the leds on gradually as i alter it.

THANKS

Is it possible to use the potentiometer as an input on the v3 board? Is there any advice, or example code which...
