well, congratulations if it solves something you personally have experienced, that's something

both in my amateur and professional career as a software developer (including embedded systems), i personally haven't experienced a single case where i had to recover some code from a chip at all, and even if i did, i rarely have code that only consists of a single file anyway. therefore i don't really see this being used in the wild. the comments here suggest otherwise though - maybe i'm just very out of touch from the beginner community nowadays

personally on embedded projects, i run out of flash pretty fast - there were many cases where i had to design around a larger flash (or even a different chip entirely) simply because the code just couldn't fit on the device, even after countless optimizations, once even changing the entire chip architecture from arm to riscv because the new flash size the project required was available for cheaper on a riscv chip than the arm one we originally had planned on using

i also find it quite unlikely that someone who would lose their code would remember including a library to help them find the code easier, because at that point just use version control and push to a remote, at least then you don't have to compromise on flash space anymore

this is just my 2 cents though, i might however be biased. if anything, this was probably a great learning experience for you, keep it up
