Product Information

The Joy-IT 84X48 LCD Display (SBC-LCD84x48) is a compact and easy-to-use display module that can be connected to an Arduino or Raspberry Pi. It has a resolution of 84×48 pixels and can display text and graphics. It is powered by SIMAC Electronics GmbH and is available in two revisions.

Connecting the Display to an Arduino
To connect the display to an Arduino, a logic level converter such as the KY-051 Voltage Translator from Joy-IT is required as the display has a 3.3 V logic level, while the Arduino has a 5 V logic level. Not using a logic level converter may cause damage to the display. Follow the steps below to connect the display:

Connect the display to the A-side of the Voltage Translator as per the table or picture in the user manual.
Connect the B-side of the Voltage Translator to your Arduino.
Ensure that the correct code example is installed in your Arduino IDE and uploaded to your Arduino.
Make sure that the correct settings are made under Tools > Board and Tools > Port.

Connecting the Display to a Raspberry Pi
To connect the display to a Raspberry Pi, follow the steps below:

Connect the display to the pins of your Raspberry Pi as per the table or picture in the user manual.
Ensure that the correct code example is installed in your Raspberry Pi.

GENERAL INFORMATION

Dear Customer,
thank you for choosing our product. In the following, we will show you what to pay attention to during commissioning and use. If you encounter any unexpected problems during use, please feel free to contact us. The display can be used with many common developer boards such as Raspberry Pi or Arduino, for example, to display measured values or measured value graphics directly on the microcontroller or single-board computer.

DIFFERENCES BETWEEN THE REVISIONS

This product has a new revision that replaces the previous revision. These changes include the pin out, the LED and the silkscreen. Below you can see 2 drawings of the different revisions.

Revision 1

Revision 2

USE WITH AN ARDUINO

Connecting the display (REV 1)
Connect the display as shown in the following picture or table to the pins of the “A-side” of your Voltage Translator and then from the “B-side” of the Voltage Translator to your Arduino. Here we recommend the KY-051 Voltage Translator from Joy-IT. It is necessary to use a logic level converter, because the display has a 3.3 V logic level, while the Arduino has a 5 V logic level. Not doing so may cause damage to the display.

Code example Arduino
This example uses the Adafruit PCD8544-Nokia-5110-LCD-library library, which is released by Adafruit under the BSD license. After installing this library in your Arduino IDE, you can find a code example at File → Examples → Adafruit PCD8544 Nokia 5110 LCD Library → pcdtest. You can upload this code to your Arduino using Upload. Also make sure that the correct settings are made under Tools → Board and Tools → Port.

USE WITH A RASPBERRY PI

Connecting the display (REV 1)
Connect the display to the pins of your Raspberry Pi as shown in the following picture or table.

Code example Raspberry Pi

Installation of the libraries
To allow you to use the display as quickly and easily as possible, we will resort to the Adafruit_CircuitPython_PCD8544 library from Adafruit, released under the MIT license. Open the console and execute the following commands:

sudo apt update
sudo apt upgrade -y
sudo usermod -a -G i2c,spi,gpio pi
sudo apt install python3-dev python3-pip libfreetype6-dev libjpeg-dev build-essential -y
sudo apt install git -y
sudo pip3 install adafruit-circuitpython-pcd8544
sudo raspi-config

To enable the SPI and I2C interface, you must first enter the raspi-config. Then select the option “3 Interface Options” and go to “I4 SPI” to enable the SPI interface. Confirm your selection by pressing “OK”. To enable the I2C interface, go to “3 Interface Options” again and select “I5 I2C” and confirm your selection by pressing “OK” as well. After you have enabled both I2C and SPI, you can restart your Raspberry Pi by entering the following command.

sudo reboot

Using the sample codes
Now the installation of the display is complete. Now open the console again and create a new folder and file with the following commands:

mkdir SBC-LCD84x48
cd SBC-LCD84x48
nano Displaytest.py

Now you still need to copy the following code into the file. Of course, you can modify this example according to your wishes and ideas. You can also download this code example here.

$joy-it-SBC-LCD84x48-84X48-LCD-Display-fig- $8$$

After you have copied the code into your file, you can save it by pressing “CTRL+O” and close it by pressing “CTRL+X”. Finally, to ensure that the code example works properly, you need to download and unzip the font file. To do this, run the following two commands. To make sure everything works, the unzipped font file must be placed in the same folder as the code you want to run.

wget https://joy-it.net/files/files/Produkte/SBC-LCD84x48/font5x8.zip unzip font5x8.zip

The following command then executes the file with its code python3 Displaytest.py and you can end the code with CTRL+C.
