LCD tutorial - LCD type HD44780 interfacing tutorial with microcontroller PIC, 8051 and AVR. LCD commands and instruction with examples.

Find out how to wire an LCD to an Arduino, and how to use the LiquidCrystal library through a set of useful examples. This article was revised on 2021/11/18 by Karl Söderby. The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver.

The LCD instruction set consists of the commands you can send to LCD. Remember that the RS line needs to be set to zero to send instruction to the LCD. When the RS line is set to one, you are sending data to display memory or the character graphics (CG) memory.

In this article, we will learn how to interface an LCD with an 8051 microcontroller. It is not very hard to interface an LCD with an 8051 microcontroller if you already know how to use KEIL for programming and how to use the input-output ports of the 8051 microcontroller. We can use LCD to display alphabets, numbers, messages, etc.
