Unfortunately, most people sprinkle a few comments here and there, which is helpful 5 years later if you have the source code. (Ask me why I developed that habit for everything I have coded for the past 30 years.) Doing so, facilitates just the exercise I am suggesting. This won't be productive unless the original programmer liberally included Serial.print() statements throughout the code, something I STRONGLY RECOMMEND as a programming habit to develop. If, in fact there is any output that you can observe, make it a task to create your own new code to emulate what the program DOES.

That is, run the program and take careful notes of what happens (via Serial Monitor or whatever). None of the variable names are preserved, and the way the compiler optimizes code, even the structure of the code would be hard to determine.Īnother approach might be to treat the program onboard the Arduino as a black-box exercise. In the "long sketch" case - it just isn't worth it. In the "short sketch" case, you are better off just rewriting from scratch.

Your sketch was long, in which case it would be virtually impossible to turn it back into C.

Your sketch was short, in which case you might, after weeks of work, turn the assembler code back into C.

There are likely to be one of two scenarios: Run on one of the bootloader files I get these results (in part): 00007e00 :Īs you can see, not particularly helpful for reproducing what your sketch did. Unless your objective is to simply copy the identical code to another device, the simple answer is: noĪs has been pointed out in other answers, you can turn the hex code on the device back into assembler code.įor example (once you have copied the code from the device back onto your disk): avr-objdump -j.
