MISO			Master in slave out. Unused
MOSI	D23 : GPIO23	Data	Master out slave in.
SCK	D18 : GPIO18	Clk	Clock.
DC	D4 : GPIO4	DC
CS	D5 : GPIO5	CS	Chip select.
RST	D2 : GPIO2	Rst	Reset.
V+	3v3	Vin

Usage

The SSD1306_SPI driver has a simple interface.

To clear the screen:

oled.fill(0)
oled.show()

To invert colors:

oled.invert(True)

A DisplayWriter was added as a convenience to writing out messages to the OLED. Use this for printing text messages to the display. Newline characters will dwa
