    Can't wait to return home... use the following ACDetect routine instead.
    this should work.
    Code:
    disable
    ACDetect:
    if ACline==1 then 
        '
        '    Rising edge of AC signal
        '    ========================
    	if triacdelay then              ' A delay is set by user
                                            '  
    	    if FullBright==0 then       ' Full Brightness flag is not set
                pauseus maxdelay-triacdelay '    do the selected delay
                triac=1                     '    enable TRIAC	    	
                else                        '
        	        triac=1                 ' Full Brightness flag is set
                                            '    enable triac
                endif                       '
                                            '
            else                            '
        	    triac=0                     ' No Delay set by user... disable Triac
            endif                           '
        
        else                                
        '
        '    Falling edge of AC signal
        '    =========================
            if fullbright==0 then triac=0   ' Disable the Triac on falling edge of 
                                            ' Ac signal
        endif
    INTCON.0=0 ' Clear GPIF (interrupt on GP4 change)
    resume
    enable
    Yeah i know you can also use Pulsout and forget the Falling edge detection... as you wish. Both will work.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
