Hi,

I've just tried to explain you you were reading your outputs instead of the inputs ...

Of course, MPSIM has some trouble with that !!!

The HIGH and LOW commands automatically set the respective pins to outputs....but the few input statement still won't work....

Also, PIR is a named register on PICs. You might not want to use that name for a variable. Might mess you up in the future. Same with RESET (could be confused with the MCLR function somewhere sometime) and ACC (some might confuse that with Accumulator).

Hi, Skimask

the "reserved word" is PIR1 ... then, no Pb with PIR.


Now look at output initialisation :

- the named outputs are declared as inputs in the TRIS ... and vice-versa.

PIR - just pointing the PIR out as well as the others for future reference, something that might cause a problem in the future.

I/O - yep, noticed that right away, but you got to it first

Hi, Skimask

You know what ???

I really DO HATE "tuning" ....

LOL

More to try

1)Turn the Comparators OFF to get PORTA to work as intended

2)

TRISA = %11111111

You set all of PORTA inputs here but make them outputs in your code

3)

TRISB = %11000000 'portb.6 and .7 out puts all others in put

You got the comment backwards (0=output, 1 = Input)

4)Remember RA4 is open drain so it needs a pullup on your real circuit

5)
Oh, and it it were me, I would start with this and make this work with the Simulator

TRISB=1
MAIN:
IF PORTB.0 = 1 then
	PORTB.1=1
ELSE
	PORTB.1=0
ENDIF
GOTO MAIN

Post back after you try some of these

I have made these changes:
1 trisa is now %00000000
2 trisb is now %00111111
3 pir is now pirin this should reduse any confusition.
Would this be correct? I will later change armed from porta.4 to portb.6 to not have to use a pull up resister and reduse current draw to a min.

I think I missed something in the translation...

Now that i have the input output thing fixed, I have determined that the program is hanging in the "pause" statments, is there a trick to get thes to work? I changed them to "pauseus" and everything seem to be perfict. Thank you to all that help this noobe.
