16F88 Analog In

In theory, you shouldn't take care of ADCONx too much when using ADCIN as the DEFINEs should take care of it for you. The only one thing you might need to set is the Right-Justified results when you use 10Bits resolution. This said, i'm not an ADCIN user.

try those settings...

	Define OSC 4
	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 uSec

	CMCON = 7 		' Disable analog comparator
	ANSEL = %01000000 	' set AN6 (RB7) as analog, others to digital
	ADCON1.7 = 1		' Right justified results... duh... really needed in 8 bits???

	adval VAR BYTE

        PAUSE 500 ' lcd settle time

loop: 	
	ADCIN 6, adval 				' Read channel 6 (RB7)
	Lcdout $fe, 1,"Value: ", DEC adval 	' Clear the LCD and show result
	Pause 250				' wait a litlle bit
	Goto loop 				' Do it forever

Notice that your analog source impedance must be lower than 10K
