-Simple library for interfacing with Nokia 5110 LCD display (https://www.sparkfun.com/products/10168)
+@brief  Simple library for interfacing with Nokia 5110 LCD display (https://www.sparkfun.com/products/10168) using the hardware SPI on the mbed.
+The display is powered from a GPIO pin meaning it can be controlled via software.  The LED backlight is also software-controllable (via PWM pin).
+-Can print characters and strings to the display using the included 5x7 font.  
+-The library also implements a screen buffer so that individual pixels on the display (84 x 48) can be set, cleared and read.
 
-Chris Yan's Nokia5110 Library proved a useful starting point.
+Acknowledgements to Chris Yan's Nokia_5110 Library.
