A Node.js Hitachi HD44780 LCD driver for Linux boards like the Raspberry Pi Zero, 1, 2, or 3, BeagleBone, or BeagleBone Black. Heavily inspired by the Arduino LiquidCrystal library.Most LCDs compatible with the HD44780 have a sixteen pin interface. This Node.js module uses six of these interface pins for controlling such displays. Register select (RS), enable (E), and four data bus pins (D4-D7). The read/write (R/W) pin is assumed to be tied low to permanently select write mode.
