Smoke!

The big square chip on my javelin started smoking. I'm looking at my breadboard and I can't find the cause of it. Miswiring the I/O lines won't cause it to smoke will it? It will only damage that individual I/O line, right? Now it starts smoking when I turn it on and I can't download any programs to it. Any suggestions on what could be the cause of it would be greatly appreciated, thanks.

    I would disconnect all circuitry from I/O pins
    and check if no external power is supplied to the
    VDD pin of the javelin, only to the VIN pin.

    Ok, I rechecked my circuit and I found I hooked the battery's power wire to VDD smhair.gif . I plugged the battery in again after fixing the connection, and it doesn't smoke anymore, but I can't download anything to it. Oh well, guess it's a goner. I'm going to double check all my connections before plugging in my second javelin rolleyes.gif . Thanks for the quick response.
