The LED backlight is also software-controllable (via PWM pin). @brief Can print characters and strings to the display using the included 5x7 font. @brief The library also implements a screen buffer so that individual pixels on the display (84 x 48) can be set, cleared and read. @brief The library can print primitive shapes (lines, circles, rectangles) @brief Acknowledgements to Chris Yan's Nokia_5110 Library. @brief Revision 1.3 @author Craig A.
