Editing AVR-Keyboard (section)

==Flashing the firmware==
===Linux===
Install dfu-programmer
 sudo apt-get install dfu-programmer
Reset the controller, and run the following commands
 sudo dfu-programmer atmega32u4 erase; sudo dfu-programmer atmega32u4 flash avr_keyboard.hex; sudo dfu-programmer atmega32u4 start 

===Windows===
==== Atmel Flip ====
You need the Atmel [http://www.atmel.com/tools/FLIP.aspx Flip] software installed to your system.  If you find that USB comms is not working, use these directions: [[Flip-USB]] 

# Plug in your keyboard
# Start Flip
# Click the Chip icon (first one)
# Select the ATmega32U4 from the list
# Click the USB icon
# Get your KB to jump to the bootloader (both shifts, or a magnet over the controller)
# Click Open (keep trying, takes a moment for the chip to be ready after jumping to the bootloader)
# Click the File menu and select your HEX file
# Click Run on the bottom left
# Click Start Application on the bottom right
# Wait a moment and your KB should be live with your new firmware

==== dfu-programmer ====
Since version 0.5.5 there is a windows binary and drivers available [http://dfu-programmer.sourceforge.net dfu-programmer-win]. The usage is obviously the same as the linux-version of it. You might want to delete the versionnumber in the filename in order to make it work with existing Makefiles too. 
 dfu-programmer atmega32u4 erase
 dfu-programmer atmega32u4 flash avr_keyboard.hex
 dfu-programmer atmega32u4 start
