Format EEPROM

The 24LC256 EEPROM chip needs to be formatted correctly for use with the MB firmware.

The firmware initialization sketch should work with any jumper configuration, but to see the LED confirmation after a successful upload it needs to be set the same as for the Alpha firmware.

Upload the following firmware to the Atmega processor: Groovesizer_ALPHA_EEPROM_INIT_001

CAUTION: formatting the EEPROM will erase any patches and patterns currently stored on it.

After a moment, the Groovesizer will start scrolling through the alphabet from A to Z and the numbers 1 to 9 on the LED grid. This is an indication that the EEPROM has been formatted successfully.
