Dead Pin?
I'm experiencing what appears to be a dead I/O pin. I cannot seem to do anything with that pin. Even with a simple LED circuit if I use pin 14 it doesn't work. All of the other pins seem to work fine. I've visibly inspected the BS2 and the socket on the board of education and all appear in good order. Is it possible that I've just done something bad and killed that pin? I'm considering just ordering a new BS2 but that won't do me any good if it is the board of education that's the problem. Can anyone here offer any advice, or is this just going to be trial and error at the cost of $$?
Thank you,

I hope that helps you.
It certainly is possible to burn out one I/O pin. I have one and only one Basic Stamp around here that is that way and I use it for more funky projects as very often I don't need anywhere near 16 i/o pins.
I have also broken off pins and soldered on my own (taken from an old IC or a piece of #20 wire) repairs rather than send them back to Parallax (a long, long way from tropical Kaohsiung).
These things are just facts of life - wear and tear occurs as you jump into your Basic Stamp adventure. I kind of admire the more beat up Basic Stamps because amongst my collect all are still in use and so far I've only killed the one i/o pin.
And I greatly admire that for all the screw ups, I haven't yet destroyed one BS completely. (Suggestion - when you first power up a new circuit, keep one finger on the BS and if you finger gets burned; kill the power.) The SXes are very rugged processors, so is the Propeller.
The funny thing is that ALL my damage has occurred to pins at the four corners of the package. They certainly seem to be the easiest to damage.
