The E1832 E1833 Alphanumeric LCD Display Switch Interface uses only 3 microcontroller pins to write bytes to a standard character LCD and 2 pins to read two tactile switches such as for Select and Enter functions, making it a simple user interface for small microcontrollers where few port pins are available. LCD instructions or data are sent serially as eight data bits plus the Register Select bit where they are converted to parallel format at the LCD connector. A single pulse on the LCD Enable completes the write. The board is available is standard and reverse pinouts to accommodate either LCD connector pinout placement.
