I think i burned it out

Hey guys,

I picked up an Arduino with a ATmega328 IC. I think i may have messed it up because when i was using it, i know i may have shorted something out when i put it away, and ever since then it’s been acting wierd. programs wont transmit to the chip, ect.

I believe that the board is ok, because when i plug it in without an IC, it fires up fine. when i add the IC, it keeps blinking the L light on pin 13 really fast.

Upload doesn’t work, reset doesn’t work, i think im stuck

can anyone point me to some somewhat cheap replacements for my Atmega328?

it reads Atmel Atmega328-20p


Maybe it’s just the bootloader that is damaged. It can be “re burned”

I thought of that, i downloaded winavr i think it’s called, but i dont know how to do that.

I have a project due for a potential customer and i need this thing going…right now im lookin for somewhere that can send me one PRONTO!!!

Please help me figure this “re-burn” thing out, it hope it works!

You can get a replacement processor (with bootloader in place) for about $6 from most of the regular Arduino suppliers.
If time is of commercial value, it might be worthwhile having a spare complete known-good board… [smiley=wink.gif]

if it is just the upload that doesnt work make sure you check you got the right serial debug speed in the arduino preferences file (http://www.arduino.cc/en/Hacking/Preferences): i thought mine was fried to,could not upload and it turned out it was just this setting preventing it from working.
