program crashes: is it my code or the chip?

Hi,
I don't see how the WaitForRelease routines is supposed to wait for the button to actually BE released.

Yes, at the point of entering the routine it does check if the button IS released but then it GOTOs main no matter what. So, the only way to have LEDState set to the correct state is if the button is already released at the time the program enters the routine. If the button is NOT released when the program enters the routine it'll just skip what's inside the IF/ENDIF block and go right to the GOTO main.

first ...

#config 
__CONFIG _CP_OFF & _WDT_OFF & _BODEN_ON & _PWRTE_ON & _INTRC_OSC_NOCLKOUT & _MCLRE_OFF & _CPD_OFF
#endconfig


LED Con 0 'Alias GPIO.0 to LED
LED2 con 1 'Alias GPIO.1 to LED2
LED3 con 4 'Alias GPIO.4 to LED3
LED4 con 5 'Alias GPIO.5 to LED4

changed to

#config 
__CONFIG _CP_OFF & _WDT_ON & _BODEN_ON & _PWRTE_ON & _INTRC_OSC_NOCLKOUT & _MCLRE_OFF & _CPD_OFF
#endconfig



LED VAR GPIO.0 'Alias GPIO.0 to LED
LED2 VAR GPIO.1 'Alias GPIO.1 to LED2
LED3 VAR GPIO.4 'Alias GPIO.4 to LED3
LED4 VAR GPIO.5 'Alias GPIO.5 to LED4

to be sure ...

now ... your sketch looks somewhat ... surprising, and not obvious at all.

could you post a scheme and a description ( in words ) of what you intend to have like a functionning scheme ???
