# 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.org website; including the Javascript Blocks Editor and Micropython
