The OS Switcher is a little USB device for dual-booters. The physical switch lets you select the operating system (OS) you want to use for the next boot. It saves time by eliminating the need to have the boot manager wait for a selection before continuing with the default option. It also removes the need to interrupt the boot process at the right time and manually select the operating system using a keyboard or mouse if not booting into the default OS.
This project is about creating an airplane instrument (such as an altimeter) for a flight simulator running on a PC. It is implemented using a 2×16 character Text LCD display and an mbed microcontroller connected to the PC using a USB cable.
