Retrieving loaded sketch from Arduino Board

Hi everyone,

I have a problem, I loaded a sketch onto my Arduino, my computer crashed and I did not save the sketch. Is there some manner of retrieving the loaded sketch?

Thanks stefan

No. You can retrieve the .hex file that was loaded, but you will not be able to recover the human readable sketch from that.

oh man...what the .hex file do or help? thanks for the help

You're basically hosed. Recreate your sketch. The hex file would just be a long string of numbers you cannot do anything with:

ex: 00 05 40 af 4e 33 56 29

for a total of 32768 bytes.

Get a USB stick and backup your files there in the future.
