Alphanumeric LCD 4x20 HD44780 - Blue LCD QC2004A

wyswietlacz lcd 4x20 hd44780

Universal alphanumeric LCD 4x20 , powered by 5 volts.

It is characterized by simple operation, high availability and numerous support for many microcontrollers.
With libraries, you can easily hook up the display to an Arduino and display subtitles. The library gives you the ability to select the column and row in which to display the inscription, or string of digits.
So you can display a great deal of information in a clear way.
The display is integral in the world of electronics, because sometimes the project will not be near a computer and there will be no way to display information on its screen.
If the display uses too many pins, you can buy an I2C converter so that the LCD will be connected through 4 wires (power +, minus -, SCL and SDA).

Product features

  • Universal alphanumeric LCD display module 4x20 characters.
  • 4x20 LCD display
  • Blue backlighting
  • White marks
  • HD44780 compliant driver.
  • Ability to define your characters
  • In the standard set of libraries and sample programs downloaded from the Arduino environment is the LiquidCrystal library, which allows you to operate the display.
  • Control - The display can be controlled in modes:
    • 8-bit without reading the busy flag - eight data bus lines and two control lines (RS, E - RW connected to ground) are required for transmission.
    • 8-bit with busy flag reading - eight data bus lines and three control lines (RS, E, RW) are required for transmission.
    • 4-bit with read busy flag- four data bus lines and three control lines(RS, E, RW) are needed for transmission.
    • 4-bit without reading the busy flag - transmission requires four data bus lines and two control lines (RS, E - RW connected to ground).

Our expert suggests

The display works with the liquid crystal library, but the following changes are needed: Connecting to the microcontroller: RS - pin 12, RW - pin 14, E - pin 11, D4 - pin 7, D5 - pin 8, D6 - pin 9, D7 - pin 10.

The program from the Arduino side looks as follows:

Guide

Wyświetlacze ciekłokrystaliczne i ledowe
Mamy za sobą podłączenie czujników do Arduino. Więc warto dane, które z nich wychodzą wyświetlić na zewnętrznym wyświetlaczu. Tak aby cały system działał niezależnie od komputera i w dodatku lepiej wyglądał. Wiedza ta też pozwoli nam na stworzenie ciekawych projektów.
