About timing in pic basic pro

Dear all,

My program :

PortA.0 = input
PortB.0 = Output 1
PortB.0 = Output 2

I want to check condition for the PortA.0

If PortA.0 = high, PortB.0 will set high. ( PortA.0 will be check for 30 second only, if
portA.0 still = low after 30 second PortB.1 will high.)

some body can help me how to program for this situation.

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...

Code:

---

        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
