Software doesn't break, it may have bugs ... hardware breaks...


Something must have changed for it to work then fail...

The important word is CHANGED.

Something may not have BROKEN, but there is a difference the compiler can detect.

Remember, you are smarter than the compiler, it’s just faster !

What error message are you getting from the compiler?
Have there been any updates to any of the libraries, board packages, or the compiler itself?

My guess... one of the libraries being used has changed. Something has to change to get different behaviour.

no, you are not telling the whole story

you might look at the date/time of the file to see if it's really unchanged since the last time you believe it compiled/ran correctly.

of course in hind site it makes sense to make copies of code after each (intermediate) milestone of success. git/github seems to be the most modern tool for managing versions and likely to endure

I didn't tell more detail cause of it happened quite few times that I can't remember, sorry.
Best to you all.
