yfkwok 0:1da4db5de653 19 @brief Library for interfacing with Nokia 5110 LCD display (https://www.sparkfun.com/products/10168) using the hardware SPI on the mbed.
yfkwok 0:1da4db5de653 20 @brief 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).
yfkwok 0:1da4db5de653 21 @brief Can print characters and strings to the display using the included 5x7 font.
yfkwok 0:1da4db5de653 22 @brief The library also implements a screen buffer so that individual pixels on the display (84 x 48) can be set, cleared and read.
yfkwok 0:1da4db5de653 23 @brief The library can print primitive shapes (lines, circles, rectangles)
yfkwok 0:1da4db5de653 24 @brief Acknowledgements to Chris Yan's Nokia_5110 Library.
