# microbit-dal

The core set of drivers, mechanisms and types that make up the micro:bit runtime.

## Overview

The micro:bit runtime provides an easy to use environment for programming the BBC micro:bit in the C/C++ language, written by Lancaster University. It contains device drivers for all the hardware capabilities of the micro:bit, and also a suite of runtime mechanisms to make programming the micro:bit easier and more flexible. These range from control of the LED matrix display to peer-to-peer radio communication and secure Bluetooth Low Energy services. The micro:bit runtime is proudly built on the ARM mbed and Nordic nrf51 platforms.

In addition to supporting development in C/C++, the runtime is also designed specifically to support higher level languages provided by our partners that target the micro:bit. It is currently used as a support library for all the languages on the BBC www.microbit.co.uk website, including the Microsoft Block Editor, Microsoft Touch Develop, Code Kingdoms JavaScript and Micropython languages.
