I hope I am posting this to the right forum, if not, can someone point me to a more appropriate one.
I am trying to send keyevent commands from my Leonardo to my Android tablet, part of a head unit. I can send the commands via ADB shell on my laptop, but I cannot figure out how to send them via the arduino.
I have been looking for weeks on how to do this, I have gotten some close hits (http://www.instructables.com/id/USB-Pedal-HID-Keyboard-With-Arduino-Leonardo/) but they are in the area of sending the standard ASCII keyboard codes, and I am looking to send screen diming/brighten and sleep/wake.
Has anyone had experience in this area?
