- Install Atmel flip which will allow you to put the arduino-keyboard-0.3.hex file onto the arduino. Arduino to Keyboard: Once Atmel is installed and your board is plugged in, load Atmel up and click on the computer chip icon below the file button, select the processor of the board you are using. In my case it was a ATmega16U2.

(As the title indicates, this is about the Arduino Leonardo Keyboard Library. I would have put it in another section of the forum, but the link in the Keyboard Reference sent me here.)
In this tutorial I shall explain how you can turn your Arduino chip into a HID keyboard device. This is done by updating the Firmware on your chip with FLIP. The cool thing about this trick is that you can make your own game controller or macro keyboard with the power of the Arduino coding method, so possibility are endless for great prototypes. There are three popular boards with that microcontroller: Arduino Leonardo, Teensy 2.0, and Pro Micro (not to be confused with Pro Mini, which uses ATmega328). Arduino Leonardo is too big for our needs. Teensy 2.0 is quite expensive. Pro Micro can be had for about $4 in.
Good afternoon forum,so, I am trying to use an Arduino Micro to send keystrokes to the BIOS so that I can automate a 'boot from USB-Stick' procedure without having to connect keyboard and screen. I am testing this in a text editor window, and the Micro is 'typing' the things I want. I added a pushbutton to the Micro so that I can 'start' the procedure with proper timings, the L13 feedback shows me that the software on the Micro is working well and timings are okay, but the BIOS does not recognize any key presses.The system (mainboard/BIOS) generally works with USB Keyboards. I have a USB-Keyboard connected which I can use for the BIOS, and I have also tried the Micro with my USB-Keyboard disconnected.
I suppose this is related to the various emulation modes that exist in this arcane part of PCs/BIOS. I have had it in the past with other keyboards and other BIOSes, that a USB Keyboard/or a Keyboard on an adapter would work well in the booted Operating System, but would act up/not be recognized in BIOS/early boot.
The same problem is described here on StackOverflow: https://stackoverflow.com/questions/12682429/generic-keyboard-emulation-using-arduino-leonardo but there is no solution/no accepted answer. I have also tried to set the deviceSubClass to 1 as suggested, but no change (still works in text editor, still not in BIOS).
Any helps/hints would be greatly appreciated, thanks for helping.
Reasons why I try/have to do it this way:- I do not want to boot from the USB Stick on every single boot. Only sometimes. So I cannot just leave the stick inserted and have the system boot order configured to the USB flashdrive.- As soon as I remove the USB Stick, it disappears from the Boot Device List, so I cannot have the system automatically boot from USB if present or continue to boot regular if not.- I cannot change the mainboard hardware, the BIOS or the BIOS version, so (U)EFI is not an option atm.
Arduino Micro Keyboard Software
This is exactly what I need for a golf simulator program that runs on my Windows 10 machine (except 12 buttons for F13 through 24 is all I need). Having said that, I am a bit intimidated by the entire process because if it doesn't work, I'd be lost. Any way that I could purchase a Ardunino Uno board from you that all I'd need to do is install it inside a box and attach buttons and then plug it into my computer via USB? I'd like to build the case to house the buttons myself but the programming and updating firmware on the board may be a stretch for my skill set.
