GENERAL INFORMATION

Dear customer,

thank you very much for choosing our product.
In the following, we will introduce you to what to observe while starting up and using this product.
Should you encounter any unexpected problems during use, please do not hesitate to contact us.

USE WITH THE ARDUINO

Connection

Code example

For use, you can use the library LiquidCrystal from Arduino Libraries, which is released under the Creative Commons Attribution-ShareAlike 3.0 License.

You can download the library here. You can include the downloaded library into your Arduino IDE by adding the .zip file under Sketch → Include Library → Add .ZIP Library... . So select the downloaded library there and restart your Arduino IDE to be able to use the library. You can also go to Tools → Manage Libraries… search for Liquid Crystal and include the library that way.

Copy the following code into your IDE to test your display.
To run the code sample, click Tools Upload. Make sure that Board and Port are selected correctly under Tools.

// Import the required library
#include <Liquid Crystal.h>
// initialize the library by linking each required pin
// LCD interface to the Arduino pin number it is connected to
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
Liquid Crystal lcd(rs, en, d4, d5, d6, d7);
void setup() {
// set the number of columns and rows of the LCD
lcd.begin(16, 2);
}
void loop() {
// Set cursor to column 7, line 1
lcd.setCursor(7, 0);
// Output of the text on the LCD
lcd.print(“joy-IT”);
lcd.setCursor(8, 1);
// Output of the time in seconds since the last restart
lcd.print(millis() / 1000);
}

USE WITH THE RASPBERRY PI

These instructions were written under Raspberry Pi OS Bookworm for the Raspberry Pi 4 and 5. It has not been checked with newer operating systems or hardware.

Connection 

Since the display works with a 5V logic level, you must use a logic level converter if you want to read data from the display with the Raspberry Pi. In this example, the display is only written to, so the Raspberry Pi can be connected directly to the display.

Now, you can download the program to your Raspberry Pi with these 3 simple commands, unzip it and then run it.
