About timing in pic basic pro

[mister_e]

mmm, something is not clear in your explanation....

When you said, "PORTA.0 will be check for 30 second only" once PORTA.0=1 on or once you put the power on your PIC?

Let's say once your put the power on your pic...

        TRISA = 255
        TRISB = 0
        CounterA    VAR WORD
        PB          var PORTA.0
        OUT1        VAR PORTB.0
        OUT2        VAR PORTB.1
        
        PORTB = 0       ' Clear all leds
        CounterA = 0    ' Clear counter
Start:
        while (CounterA<300) AND (PB=0)
            pause 100
            CounterA = CounterA + 1            
            wend
        
        if CounterA>=300 then
            OUT2 = 1
            else
                OUT1 = 1
            endif
            
Spin:   GOTO Spin
