| xuszdd | 0:ee32d3554f6f | 43 | @brief Library for interfacing with Nokia 5110 LCD display (https://www.sparkfun.com/products/10168) using the hardware SPI on the mbed. |
| xuszdd | 0:ee32d3554f6f | 44 | @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). |
| xuszdd | 0:ee32d3554f6f | 45 | @brief Can print characters and strings to the display using the included 5x7 font. |
| xuszdd | 0:ee32d3554f6f | 46 | @brief The library also implements a screen buffer so that individual pixels on the display (84 x 48) can be set, cleared and read. |
| xuszdd | 0:ee32d3554f6f | 47 | @brief The library can print primitive shapes (lines, circles, rectangles) |
| xuszdd | 0:ee32d3554f6f | 48 | @brief Acknowledgements to Chris Yan's Nokia_5110 Library. |
