To setup the project and upload the Arduino usbserial application firmware to an ATMEGA32U2 using the Arduino USB DFU bootloader:
|
||||
1. unpack the source into LUFA's Projects directory
|
||||
2. set ARDUINO_MODEL_PID in the makefile as appropriate
|
||||
3. do "make clean; make"
|
||||
4. put the 32U2 into USB DFU mode:
|
||||
4.a. assert and hold the 32U2's RESET line
|
||||
4.b. assert and hold the 32U2's HWB line
|
||||
4.c. release the 32U2's RESET line
|
||||
4.d. release the 32U2's HWB line
|
||||
5. confirm that the board enumerates as "ATmega32u2"
|
||||
6. do "make dfu" (OS X or Linux - dfu-programmer must be installed first) or "make flip" (Windows - Flip must be installed first)
|
||||
|
||||
Check that the board enumerates as "Arduino Mega 2560".
|
||||
Test by uploading a new Arduino sketch from the Arduino IDE.
