Pic16f690 - detecting RF signal and leds

Hey fellas, I'm not too familiar with programming in C for the PIC16F690 -

I'm hoping I could get some pointers for the Pic16f690 I'm utilizing in my Control Circuit .. from the Rf detectors, linked to the Pic via 3x2 header , so the idea is that a comparator program, which monitors the 3 inputs, determines which one is the strongest reading and then lights up the led accordingly in that direction (3 leds on the board).

Correct me if I'm wrong, but if I were doing this :

TRISC=0x00; //Ensure pins 14,15,16 are input
ANSEL|=0x70; //Enable pins 14,15,16 for analoge input
TRISX reigister, where X is replaced with the port letter it is connected to?
TRISA=0x02; for pin 17 (as per my schematic)


If anyone can offer guidance / feedback, that'd be awesome ..
I've attached the control circuit project from Altium (if that helps )

Go have a look at the Pickit2 LPC lessons. The one on the ADC is what you are lookng for. Once you have that working it's prob easiest just to read in the MSB/LSB of the ADC and do some simple subtractions (and bit test the carry bit) to bubble sort the solution.
