How to access compilation time inside ESP-IDF application code?

Postby Garnagar » Fri May 29, 2020 3:47 pm

Is there a way to access compilation time from inside the ESP-IDF application code? Similarly to how you can access IDF version with IDF_VER?

Use the __TIME__ and __DATE__ macros: https://gcc.gnu.org/onlinedocs/cpp/Stan ... acros.html

Also there's some metadata embedded in the binary that includes these:
