-Character [[https://en.wikipedia.org/wiki/Liquid-crystal_display|Liquid Crystal Displays]] (LCD) are low-cost electronic devices that are capable of generating visual displays consisting of alphanumeric characters and graphical symbols commonly used for [[https://en.wikipedia.org/wiki/Embedded_system|embedded system human machine interfaces]] (HMI). Many suppliers of LCD devices are based on the [[https://en.wikipedia.org/wiki/Hitachi_HD44780_LCD_controller|Hitachi HD44780]] LCD controller, and hence have a common hardware and software interface. Some LCD devices have serial interfaces that use UART, I2C, and SPI communications((PmodCLS: Character LCD with Serial Interface, [[http://store.digilentinc.com/pmodcls-character-lcd-with-serial-interface/|http://store.digilentinc.com/pmodcls-character-lcd-with-serial-interface/]])). These protocols are covered in Unit 4. Other LCD devices use interfaces consisting of four or eight data lines and three control lines((PmodCLP Character LCD with Parallel Interface, [[http://store.digilentinc.com/pmodclp-character-lcd-with-parallel-interface/|http://store.digilentinc.com/pmodclp-character-lcd-with-parallel-interface/]])). Although the LCDs that use a serial interface require fewer processor I/O pins, the display controller IC is still based on the Hitachi HD44780, which uses 8 or 11 I/O pins. Hence, the serial LCD devices have an on-board microprocessor that translates the serial communications instructions to parallel I/O. +Character [[https://en.wikipedia.org/wiki/Liquid-crystal_display|Liquid Crystal Displays]] (LCD) are low-cost electronic devices that are capable of generating visual displays consisting of alphanumeric characters and graphical symbols commonly used for [[https://en.wikipedia.org/wiki/Embedded_system|embedded system human machine interfaces]] (HMI).
