get a sensor digital input to work on a pickit 2 16f690 lpc

[mister_e]

Also with the digital sensor program, the light turns on when the state changes, but won't shut off unless i push the button on the lpc. Why? Thanks again. This is the code:

In your code, your TRISC line is not right, you must set some inputs there.... as it is right now, there's only OUTPUT. Change it to

      ' 
      '  76543210
TRISC = %10000000
      ' -1-------- PORTB.7 = INPUT
      ' --0000000- PORTB<6:0> = OUTPUT

And then your main loop may looks like...

Start:
        IF PORTC.7 = 1 THEN
                PORTC.0 = 1
                ELSE
                        PORTC.0 = 0
                ENDIF
        PAUSE 1000
        GOTO Start

OR.. WAY easier

Start:
        PORTC.0 = PORTC.7
        PAUSE 1000
        GOTO Start

In your code, you enable the Pull up on PORTA, there's no internal pull-up available for PORTC, so I hope you have one

mi pickit2 constantly gets busy after around 15 seconds and i am forced to recompile why?

[ScaleRobotics]

That's because of your code in line 11.

Just kidding, how could we possibly know what the problem might be from what you wrote? So now I am going to sound like a teacher and ask for at least a sentence for each of these topics. (Nah, a teacher would have asked for a paragraph on each)

1. Gets busy? Busy doing what?

2. 15 seconds after what?

2. Recompile, what is forcing you to do this, and why?

3. What are you doing to get here?

4. Any errors?

5. Any code?

6. Are you using the PICKIT 2 Standalone application, or the command line? If so, make sure you don't run 2 instances (or more) of the application.

7. What if you change TRISA to...

TRISA = 255

The problem was solved whjen i changed the code to portc.0 = portc.7. Thanks.
