Anyone do the LED as a button on the propeller?

I did a search, but searching on LED and button, is going to get you a million posts.

    There have been several threads about this over the years. Are you looking for a specific example?

    Sure, im sure if not in propeller, then perhaps in SX or BS2..

    Once i make the prop code, i will post it here, if no one has.

    Its a neat demo, easily made.

    Exactly.

    I found a BS2 version.

    Here are a couple of examples. I haven't gotten around to trying either of them yet...

    ledinout.spin works if you use a 33ohm resistor. (not 330 or 220)


    newLEDIO works great and it does it in assembly so you can start to understand asm..

    An awesome, simple spin versus asm example right here people.

    It's explained very well in the newLEDIO.spin comments.
