Demo of Adafruit_SSD1306 graphics library and SPI interface on RedBear NANO nRF51822 board

Dependencies:   Adafruit_GFX_nano SPI_Demo_Nano

This is a test of the RedBear nano board and the Adafruit oled display. Currently not working because of some problem with the SPI driver which I can't understand.
