If you have something like an Arduino with enough available I/O pins, you can wire the display up directly to pins. You should be able to hook up power (5V to VDD, Ground to VSS, and probably some power to the backlight and maybe something to control contrast), and then connect the...

library.properties Arduino Library for LiquidCrystal displays with I2C PCF8574 adapter A library for driving LiquidCrystal displays (LCD) by using the I2C bus and an PCF8574 I2C adapter. There are modules that can be soldered or stacked to the display that offers an I2C interface for communicatio...
Despite the library's name, it supports the ESP8266, Attiny85, STM32F1 and should work with any standard Arduino-device at the moment, though, out of the official Arduino-boards, I have only tested it with Arduino Micro as I don't yet own any other ones. Usage What arguments the clas...

This paper presents a library for Arduino that allows interfacing a 16x2 LCD display with the HD44780 controller via the PCF8574 I2C expander. The library provides basic functions for displaying text and controlling the backlight on the LCD. The library is based on two previous works by Batuta...
Unfortunately I have troubles getting this library and one of your other library (for PCF8574) to work together properly. If I include both libraries, only the first one goes pass the compiler, but for the other compiler shows error. #include "Arduino.h" #include "PCF8574.h" #include "...
