# APLPi/microbit

This repository contains tools for using the micro:bit with Dyalog APL

on the Raspberry Pi, with focus on MicroPython. Morten Kromberg is blogging about his experiences with this technology on the [Dyalog Blog.](http://www.dyalog.com/blog/2017/01/raspberry-apl-pi-and-python-on-the-microbit-2/)

##The microbit class

The microbit class provides an interface from Dyalog APL to the MicroPython

REPL, using serial communications. The interface relies on the MicroPython REPL being up and running on the micro:bit. The easiest way to make this happen is to use the "mu" editor on the Pi to compile and "flash" a trivial Python programme to the micro:bit. The file `repl_prompt.py` contains a suitable bit of code which will display a ">>" prompt on the micro:bit display when it is reset (because that looks a bit like the Python >>> prompt). Once this is done, the micro:bit will power up (and can be reset to) a state where you can see the ">>" and the REPL is running.

If you cloned the repository to `/home/pi/microbit` and have started Dyalog APL, you should be able to execute simple Python commands.

        ]load /home/pi/microbit/microbit    

        mb←⎕NEW microbit ''

        mb.PyREPL '2+2'

    4

You can display morse code using the LEDs on the micro:bit using the Morse example:

        ]load /home/pi/microbit/Morse

        Morse.Init '/home/pi/microbit/MorseCode.txt'

        Morse.Display 'SOS'

A video of this in action is available [on YouTube](https://www.youtube.com/watch?v=yfGsSLEifAs).
