Now you will need to compile your firmware using make command. # part AT90USB82 which is close enough in memory size and organization # versions of either avrdude or dfu-programmer, we specify a dummy # Since the ATMEGA8U2 part is not directly supported by the current Go to firmwares/arduino-keyboard and open makefile and change MCU like that: # MCU name(s) If you know what your doing, go to this repository and clone it or download to you computer. * Keys 1, 2, 3 and 4 on pins 4, 5, 6 and 7Īt first check my previous note how to flash Arduino because you will need this knowledge to put new software on your board. Arduino Mega R3 with keys attached (scrapped from old scanner).
If you want to use other key codes check attachment on the bottom of this post. Pin connections are very simple, you should simply connect them all to GND pin of Arduino. It is a simple implementation, only four buttons 1, 2, 3 and 4 connected to four pins. So, let’s begin… This is my rather stupid keyboard operating system based on examples of others: You need to design your software before flashing new firmware because one cannot put new sketches to a keyboard 🙂 If you would like to edit your sketch and reflash it you’ll need to restore an original board firmware. This tutorial will show you how to turn Arduino into HID controller (in this case simple keyboard).
