Microbit V1 display driver

The image above shows a Microbit V1 connected to an ST7789 1.14′ display via a Kitronik breakout board. The SPI interface on the Microbit (NRF51822) is a little slow at 4MHz but it is ok for simple outputs as shown above. Code was developed using VSCode, PlatformIO the mbed framework. The full list of connections can be found in the file display.cpp which is available on the github repo over here
