help with PIC16F628 conditional program

[Acetronics2]

RA7 won't be an input until i independently configured it as an input so i placed this line

INPUT neut

Did you notice IF you want Porta.7 as an input ... the TRIS value must be > 127 ???

here you have 95 ... tadaaaa ...

this works, but for some reason instead of revers/portb.0 going steady high when the input condition rules i got some oscillations, the led connected on this on my simulation blinks

no reason for that ... simulators are just toys , so do not believe what they say ...
may be you could add some debouncing to your inputs ... but simulation won't show anything.

i didn't notice that

here's a screenshot:


this happens to all ports on portb except rb0 where i get a straight line


thanks

Could you post your ISIS file here ??? ( xxx.DSN )

Hi, Joseph

Definitly a simulator issue ... ( one MORE for Proteus ... )

Just run your program in MPSIM ( MPLAB Simulator ) in step by step mode, and you won't see any change for the output ...

I did told you Sims are toys ... , forget about them !!!

BTW, Correct code is:

 IF ( FWD ^^ REVS ) AND NOT NEUT THEN   
        forward = FWD : revers = NOT forward
       ELSE
        forward = 0 : revers = 0
       ENDIF

Doesn't change anything ... but brain satisfying !!! ( it's a logical EXOR, and not a bitwise one )

Joseph,

Add some resistors in series with the LED's that are being overdriven.
It will stop blinking.

Proteus Rules.
MPSIM is Lame.

Hi, Darrel ...

did you try to close Forward, then the two other switches ( or/and ) ...

you said " lame " ??? ... funny ...

Alain

Judge of peace: my EasyPic5 ... Proteus is OUT !!!

whoa it seems that proteus simulates the overload protection, it worked

thanks Darrel, thanks Alain

i will try to complete the code. i'l update this thread soon
