Fileinfo

Adding File information to a compiled firmware is very useful and important to identify the used software version.

This Tip provides a subfunction, returning not only all file info via serial output but also returned filename in short and long text form

Define in the main sketch as follows

#define __FILENAME__ (strrchr(__FILE__, '\\') ? strrchr(__FILE__, '\\') + 1 : __FILE__)

Once you need the data, call

versionsInfo(__FILE__, __FILENAME__);The function I use looks like this//=======================================================================// Versionsinfo//=======================================================================void versionsInfo(char* longFileName ,char* shortFileName){ Serial.print("\nArduino is running Sketch: "); Serial.println(shortFileName ); Serial.println(longFileName);
Serial.print("Compiled on: "); Serial.print(__DATE__); Serial.print(" at "); Serial.print(__TIME__); Serial.print("\n\n");}

while _FILE_ is created by the compilier, _FILENAME_ is the shortform of the main sketch only
