Arduino Uno and Mega 2560 Firmwares for the ATmega8U2
|
|
|
|
|
|
|
|
|
|
This directory contains the firmwares used on the ATmega8U2 on the Arduino
|
|
|
|
|
Uno and Arduino Mega 2560. The arduino-usbdfu directory contains the DFU
|
|
|
|
|
bootloader on the 8U2; the arduino-usbserial directory contains the actual
|
|
|
|
|
usb to serial firmware. Both should be compiled against LUFA 100807. The
|
|
|
|
|
two .hex files in this directory combine the dfu and serial firmwares into
|
|
|
|
|
a single file to burn onto the 8U2.
