Michael Hewitt / Mbed 2 deprecated microbit_serialDisplay

to verify the position of the LEDs

Dependencies:   mbed

This is an attempt to address all the 25 LEDs. This has been done but only on rows. I need to arrange the column calls in some form of array which can be indexed.

/*
 * All the LEDs on the micro:bit are part of the LED Matrix,
 * In order to get simple blinking behaviour, we set column 0
 * to be permanently at ground. If you want to use the LEDs as
 * a screen, there is a display driver in the micro:bit 'DAL',
