ATMega2560 Coding Issue

Hello All,

I am currently working with an ATMega2560 and I am having some issues. A person previously before me developed a code to run on this chip/board and I don't have the code that he used. Is there a way to extract the code from the ATMega2560 itself?
Any help is appreciated!

V/R,
Sean

How would I go about pulling the compiled machine code? I'm relatively new when it comes to retrieving machine code.

A Google search for "retrieving machine code arduino" may yield pages that can help.
