    For those curious: Atmel AVR Microcontrollers are commonly sold as Arduino. Some chips (not ATMega 328P but ATMega 32U4) have native support for USB. This allows them to be used as USB HID devices: a keyboard and mouse. Here is someone else's tutorial: https://codeandlife.com/2012/02/11/v-usb-tutorial-continued-... And a shameless plug for an app that I wrote that uses an Arduino to turn your laptop into a keyboard…

    http://codeandlife.com/2012/07/03/benchmarking-raspberry-pi-... I was wondering this too, but I never took the time to find out what this guys numbers could translate to in terms of actual throughput.

    > and each cycle on an RPi at 900Mhz is 1.1ns Its not the CPU's clock that matters here. https://codeandlife.com/2012/07/03/benchmarking-raspberry-pi... With 14MHz best-case from the Rasp. Pi, its clear that the GPIO clocks are simply at a slower rate than the CPU. Also, with C, you can achieve the highest possible GPIO rate on the Rasp. Pi. No need to go into an alternative OS.
