Who can tell me how the A/D converter works

Iám a starter so plaese keep it simple

[mister_e]

do a search for ADCIN to start.

WOW, Have you find that by your own

I like all this HELPFULL answers for BEGINNERS

Thank you very much

JARI,

Maybe if you were more specific with your question.

Do you just want to read the analog voltage on a pin?

Are you looking for an explanation about how successive approximation works?

Or, are you trying to figure out why the program you've already written doesn't work?

I want to know how I can read a analog voltage on a pin, and how to put this in
a program so I can set a other pin high or low.

Iám using pbp v2.44

You can read that in the manual which came to your version of PBP.
Here then a smal example with no comment. Try to find the comment in the manual.

		
			@ DEVICE PIC16F877A,XT_OSC
			@ DEVICE PIC16F877A,BOD_OFF
			@ DEVICE PIC16F877A,LVP_OFF
			@ DEVICE PIC16F877A,CPD_OFF
			@ DEVICE PIC16F877A,PROTECT_OFF
		

		
		
			DEFINE	ADC_BITS		8
			DEFINE	ADC_CLOCK		3
			DEFINE	ADC_SAMPLEUS	50
			DEFINE	OSC 4
			
			ADCON1	=	%00000010	

			TRISA		= %11111111
			TRISB		= %00000000   
			TRISC		= %10000001

			LEDPIN		VAR	PORTB.0

			VALUE0		VAR	BYTE

			CLEAR
			

START:			ADCIN 0,VALUE0

			IF VALUE0 > 127 THEN
				LEDPIN = 1
			ELSE
				LEDPIN = 0
			ENDIF

			GOTO START
			END

How about page 43 of the PBP manual?
Duh....
