Hi

I am using IAR. Is there an easy way to built in a timestamp in my firmware? So later on I can check when the running FW on my board was compiled?

Or does IAR come with such a feature? I a using IAR and STM32f4

Thx

Check out __TIME__ (and __DATE__) - see C99, 6.10.8.

printf('FW: %s %s\r\n',__TIME__,__DATE__); // time stamp of source file line is in.
