Here’s the video version of this tutorial, where I go through the setup and show all of the programming examples below: How to Setup an LCD on the Raspberry Pi and Program it With Python.How to Setup an LCD on the Raspberry Pi and Program it With C.If you don’t have an I2C enabled LCD or a PCF8574, these tutorials will show you how to connect an LCD with the GPIO pins: I’ll also show you how to program the LCD using Python, and provide examples for how to print and position the text, clear the screen, scroll text, print data from a sensor, print the date and time, and print the IP address of your Pi. I’ll explain how to connect it both ways in a minute. The PCF8574 converts the I2C signal sent from the Pi into a parallel signal that can be used by the LCD. But the hardcore DIY way is to use a standard HD44780 LCD and connect it to the Pi via a chip called the PCF8574. The simplest is to get an LCD with an I2C backpack. There are a couple ways to use I2C to connect an LCD to the Raspberry Pi. It covers all of the steps, diagrams, and code you need to get started. BONUS: I made a quick start guide for this tutorial that you can download and go back to later if you can’t set this up right now.
