Is it possible to copy a sketch from another microcontroller to your pc to edit

Sort of, but not really. Given enough effort you can get the binary machine code off the chip and into a PC editor, but (A) it won't be easy, and (B) it won't be pretty. What you're asking for is the equivalent of saying "here's a cake; how can I get the eggs back out".

Getting the machine code back out is easy with atmel studio or avrdude if you have an isp programmer. There's no way to get the c code back though

What you're asking for is the equivalent of saying "here's a cake; how can I get the eggs back out". I like that one a lot. :wink: Lefty

magagna: What you're asking for is the equivalent of saying "here's a cake; how can I get the eggs back out". Not really - he doesn't want the eggs, he wants the cake recipe.

modeller: magagna: What you're asking for is the equivalent of saying "here's a cake; how can I get the eggs back out". Not really - he doesn't want the eggs, he wants the cake recipe. But his is the funnier sound bite. :wink:

So is there a tutorial somewhere on how I can use atmel studio or avrdude to read the data from a chip? I'm really interested in seeing if I can reverse engineer things like that...

GDH5: So is there a tutorial somewhere on how I can use atmel studio or avrdude to read the data from a chip? I'm really interested in seeing if I can reverse engineer things like that... Just grab a .hex file from any old sketch and start from there...after that you can move onto unknown sketch…

Take a look at6 the AVRDude tutorial here http://www.ladyada.net/learn/avr/avrdude.html Example: This will copy the hexfile from arduino to the file test.hex avrdude -pm328p -Pcom20 -carduino -D -U flash:r:test.hex:i
