// ========================================
// Manage an Arduboy's system EEPROM area
// ========================================
/*
------------------------------------------------------------------------------
This sketch allows manipulation of the following values in system EEPROM:
- The Unit Name. This is a 6 character field that can be read by sketches
using the readUnitName() function. Also, the Arduboy2 class will display
the Unit Name at the end of the boot logo sequence, if possible, during
start up.
- The Unit ID. This is a 16 bit value that can be read by sketches using the
readUnitID() function.
- The "Show Unit Name" flag. This flag indicates whether or not the Unit Name
should be displayed at the end of the boot logo sequence in circumstances
where it's possible to do so.
- The "Show RGB LEDs with Boot Logo" flag. This flag indicates whether or not
to flash the RGB LEDs while the boot logo is scrolling down.
- The "Show Boot Logo" flag. This flag indicates whether or not to display
the boot logo sequence during start up.
This sketch also allows:
- The entire System EEPROM area to be reset back to default values.
- The entire User EEPROM area to be reset. This will clear the high scores
and any other data saved by ALL sketches that have ever been installed.
