Check the documentation in the opening comments of Lib/Rabbit4000/RemoteProgramUpdate/board_update.lib. It describes three macros you can define in the Project settings:
Set the following macros in your Project Defines menu to have the information embedded into the firmware, and accessible to this API.
_FIRMWARE_NAME_ String, up to 19 printable characters, null-terminated.
_FIRMWARE_VERSION_ 16-bit word (0x0000). In our sample projects, it's treated as a BCD (binary-coded decimal) value and printed as ("%u.%02x", VER >> 8, VER & 0xFF).
_FIRMWARE_TIMESTAMP_ 32-bit value, # of seconds since 1/1/1980. Defaults to using the system time at compile time, can override to get repeatable firmware images (same .BIN built from project/source files regardless of compile date/time).
