Use dfu instruction to put it on your board. After succesful compilation hex file will be created in the same directory.Ĥ.

Than in a directory cloned from a repo (where you’ve changed this specific file ) simply type:ģ. Sudo apt-get install -y build-essential avr-gcc avr-libcĢ. To compile repository with keyboard firmware you will need to install compilers:

I’ll try to explain everything to you step by step.ġ. Sorry but it’s my first time with arduino.

Have i to flash again firmware every time i have to edit and upload again my schatck? where i can find an orgnal firmware? why we dont’ have done a backup at the beginning of your procedure? I don’t have understand what do you mean with “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.” I have to enable DFU mode and erase current firmware (no backup needed?), then upload my Arduino-keyboard.hex, and finally reset it. I don’t have to do any wget becouse i suppose i have to flash my Arduino-keyboard.hex Sudo apt-get update & sudo apt-get install dfu-programmer Which file has to be named Arduino-keyboard.hex?įollowing your next link i think i have to run: I have edited my sketch, downloaded zip file from github (and modified the makefile as you described), but now can you describe step by step how to compile? Burn it to your Arduino device using previously mentioned tutorial. File with your software will be named Arduino-keyboard.hex. 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).
