DCS-BIOS connects custom-built control panels powered by Arduino microcontroller boards to the flight simulator DCS World. It can also be used by other programs to interface with DCS.

At the very basic level, it is an Arduino Library that will recieve and send data to and from your PC running DCS World over USB.

The Control-Reference documentation is included in the doc/ subdirectory in the DCS-BIOS download. Simply double-click Control-Reference.html to open it in your web browser.

Welcome to the DCS-BIOS User Guide.

This manual will explain how you can use DCS-BIOS to connect the clickable cockpit of a DCS: World aircraft to real-world hardware such as toggle switches, push buttons, rotary encoders, potentiometers and displays.
