Sudo dfu-programmer at90usb82 flash -debug 1 Arduino-keyboard-0.3.hex Assuming everything flashes normally, we can move forward with flashing the HID keyboard firmware.
Plug cycle the Arduino, then open the Arduino IDE and ensure that you can still upload a sketch. Sudo dfu-programmer at90usb82 flash -debug 1 Arduino-usbserial.hex The Arduino bootloader firmware can always be updated using the DFU protocol! sudo dfu-programmer at90usb82 erase NOTE: There is no chance of ‘bricking’ the device using this method. This will confirm that the programmer and the environment are both functional. The first step is to make sure you are able to flash the standard arduino firmware.

On Ubuntu and Debain systems, in a terminal run: sudo apt-get install dfu-programmer dfu-utilįor Windows and Mac instructions to install the dfu-programmer tool, consult the official Arduino DFU documentation. For more info, check out the USB HID Spec sheet.īefore you start, install the required packages. The USB HID protocol provides manufactures the generic specifications to interact with nearly every operating system in existence. In this demonstration, we will flash generic USB HID keyboard firmware. This is made possible in part to the wonderful open source LUFA (Lightweight USB Framework for AVRs) USB stack, and keyboard HID firmware from Darran. This allows the device to be recognized as many other device types, including keyboard, mouse, joystick, midi device, etc.

However, in addition to the ability to flash standard USB Serial firmwares, we can also flash alternative firmwares as well. Note: If your board is NOT an Arduino UNO SMD you’ll need to solder a 10k resistor (Brown-black-orange) at the back of your board as shown on the Arduino site. This process is normally used to update the firmware to a more recent version, as explained in the offical Arduino guide, Updating the Atmega8U2 on an Uno or Mega2560 using DFU. This is completely independant of the ‘normal’ method of flashing sketches to the board using the Arduino IDE. The Atmega8U2 chip on the Arduino UNO can be programmed directly using the special USB protocol called Device Firmware Update (DFU). All this is made possible by the use of the Arduino Device Firmware Update (DFU) function. The USB HID keyboard conforms to the standard USB specification, so is functional on all modern operating systems. Make it a useful tool, with new buttons for Cut/Copy/Paste or Volume+/Volume-/Mute, or annoy your friends and colleagues by setting the keyboard to perform random keypress after random delays! Turn your Arduino UNO into a USB HID keyboard, and make buttons that do whatever you want.
