revolution counter

crap.. I forgot to define my ADC:

Define ADC_BITS 8 ' Set number of bits in result
Define ADC_CLOCK 3 ' Set clock source (3=rc)
Define ADC_SAMPLEUS 50 ' Set sampling time in uS

So it is working now???

I dont know if it works, I m at work now, I will see when I get home tonight

skimask, what do you mean by tripping?
:is this it...

ADCON0.2 = 1 'Start Conversion
ADCIN 1, Output_Pot 'analog pin 1 (RA1) get the 8 bit result

Ok, I see there's 2 places where I could be 'tripping' !

1st tripping - by that I mean the point where the ADCIN routine distinguishes between the light and dark area of the disc.

2nd tripping - Do you see this phrase anywhere in the manual?

ADCON0.2 = 1 			'Start Conversion

I.E. YOU don't need to start the A/D conversion, ADCIN does that for you.
