Replicator 1 desktop 3d printer
driver by Felipe Correa da Silva Sanches <fsanches@metamaquina.com.br>
Changelog:
2013 DEC 28 [Felipe Sanches]:
* LCD now works. We can see the firmware boot screen :-)
2013 DEC 24 [Felipe Sanches]:
* declaration of internal EEPROM
2013 DEC 18 [Felipe Sanches]:
* Initial driver skeleton
*/
// TODO:
// * figure out what's wrong with the keypad inputs (interface seems to be blocked in the first screen)
// * fix avr8 timer/counter #0 (toggle OC0B) and #5 (overflow interrupt "Microsecond timer") so that we get the buzzer to work
// * figure-out correct size of internal EEPROM
// * emulate an SD Card
// * implement avr8 WDR (watchdog reset) opcode
