+Example of using SHARP LS013B4DN02 with MSP430 LaunchPad
+========================================================
+
+SHARP LS013B4DN02 is a very low power 1.35 inch, 96x96 pixel LCD display. It uses
+less than 15 uW when displaying a static image.
+
+http://www.sharpmemorylcd.com/1-35-inch-memory-lcd.html
+
+Mouser indicates this model as end-of-life. However LS013B4DN04 has very similar
+specifications and should also work with this code and breakout board.
+
+As the display comes with 0.5mm pitch FPC cable I designed a basic breakout board
+with a matching connector and the recommended decoupling capacitors.
+
+Wiring on MSP430 LaunchPad to LCD breakout:
+* P1.0:	LED  (VCOM status display)
+* P1.4:	DISP (display on/off)
+* P1.5:	SCLK (SPI clock)
+* P1.6:	SI   (SPI data)
+* P1.7:	SCS  (SPI chip select)
+* GND:	GND
+* VCC:	VDD and VDDA	(even though specified 5V, the display works fine at 3V)
