Hi Mat,

I corrected the typo "CMCOM.7", it should ofcource be "CMCON.7", PBP should give you an error.

I use SEROUT instead of LCDOUT, no big deal there exept the fact that you had "LCDOut, COUNTERT". Two things about that line, first - it's "syntax error", the comma shouldn't be there. Second - you have no ASCII operator such as #,DEC,HEX,BIN or whatever. This line would most of the time show garbage on your display. You should also change "DEFINE LCD_DBIT 4" to "DEFINE LCD_DBIT 0" since you use the lower half of PortB.

However, none of this LCDstuff should affect the operation of the Comparator. I got so puzzled by your problem that i just had to give it a testrun. I can now inform you that this code works just fine, i ran it on a 16F628 ten minutes ago. If you can't get this code to work, it just has to be a hardware problem.

Code:
	@ DEVICE PIC16F628,XT_OSC
	@ DEVICE PIC16F628,MCLR_ON
	@ DEVICE PIC16F628,BOD_OFF
	@ DEVICE PIC16F628,LVP_OFF
	@ DEVICE PIC16F628,CPD_OFF
	@ DEVICE PIC16F628,PROTECT_OFF
		
	DEFINE	OSC 4
	
	HULP1		VAR	BIT
	HULP2		VAR	BIT
	PULS		VAR	CMCON.7
	COUNTERT	VAR 	BYTE

	CMCON = 5 

	TRISA	=	%11111111
	TRISB	=	%00000000
	
	Clear
	
BEGIN:
	IF PULS = 1 AND HULP1 = 0 Then 
		HULP2 = 1
	Else 
		HULP2 = 0
	EndIF
		
	IF PULS = 1 Then 
		HULP1 = 1
	Else 
		HULP1 = 0
	EndIF				
		
	IF HULP2 = 1 Then COUNTERT = COUNTERT + 1
		
	serout2 PortB.0,84,["CMP2 = ",BIN1 PULS, "   HULP1 = ",BIN1 HULP1]		
	serout2 PortB.0,84,["   HULP2 = ",BIN1 HULP2, "   COUNTERT = ",DEC3 COUNTERT, 13, 10]		
	PAUSE 100
		
	GoTo BEGIN

Oops, crap, not that it matters much but i just realized that i made a mistake in my last post. Your code couldn't be reduced to what i suggested. I read the first IF-THEN statement wrong. Sorry.
