Richard Ellingworth / Mbed 2 deprecated RobotRic

Version of Robotron arcade game using LPC1768, a Gameduino shield, a serial EEPROM (for high scores), two microswitch joysticks and two buttons plus a box to put it in. 20 levels of mayhem.

Revision:
2:bb0f631a6068
More code brought in from Maple version. Now uses fancy character set and displays Robotric logo. Started re-writing I2C EEPROM code as SPI EEPROM code since now using an SPI EEPROM but not finished yet.

Who changed what in which revision?
