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.

SETUP OF THE DISPLAY INTERFACE

The display can be controlled in 4 different ways, via I2C, SPI, 8-bit parallel 6800 interface, and 8-bit parallel 8080 interfaces.
The display is delivered pre-configured for control via SPI. If you want to use one of the other control methods, you have to re-solder the resistors BS1 and BS2 on the back of  the board.
In the table, you can see how the resistors must be set for the respective mode.

| 6800-parallel| 8080-parallel| I2C| SPI
---|---|---|---|---
BS1| 0| 1| 1| 0
BS2| 1| 1| 0| 0

USE WITH AN ARDUINO

As the display works with a 3V logic level and most Arduinos with 5V, we use an Arduino Pro Mini 3.3V in this example. If you want to use an Arduino with a 5V logic level,  such as an Arduino Uno, you have to reduce all data lines leading from the Arduino to the display from 5V to 3.3V with a logic level converter.
First, you need to install the required library in your Arduino IDE.
To do this, go to Tools - > Manage Libraries… Search for u8g2 and install the library U8g2 by Oliver

Now open the GraphicTest code sample of the library. To do this, click on:
File - > Examples -> U8g2 -> u8x8-> GraphicTest 
Now insert the following constructor for the display into the program, as shown in the picture below:
U8X8_SSD1309_128X64_NONAME2_4W_SW_SPI u8x8(13, 11, 10, 9, 8);

Now you can upload the example to your Arduino.

Now insert the following constructor for the display into the program, as shown in the picture below:
U8X8_SSD1309_128X64_NONAME2_HW_I2C u8x8(9, A4, A5);

Now you can upload the example to your Arduino.

Now insert the following constructor for the display into the program, as shown in the picture below:
U8X8_SSD1309_128X64_NONAME0_6800 u8x8(13, 11, 2, 3, 4, 5, 6, A3, 7, 10, 9, 8);

Now you can upload the example to your Arduino.

Now you can upload the example to your Arduino.

USE WITH THE RASPBERRY PI

To make using the display with the Raspberry Pi particularly easy, we use the luma.oled library.
You can install the dependencies required for installation with the following commands:

sudo apt-get update
sudo apt-get install git python3 python3-dev python3-pip python3-pip python3-pil libjpeg-dev zlib1g-dev libfreetype6-dev liblcms2-dev libopenjp2-7 libtiff5 build-essential  libsdl-dev libportmidi-dev libsdl-ttf2.0-dev libsdl- mixer1.2-dev libsdlimage1.2-dev

First, we install the library and download the sample files, this is done with the following  commands:

sudo -H pip3 install –upgrade luma.oled  sudo git clone https://github.com /rm-hull/luma.examples.git
Next, you must give the user (in this case “pi”) permission to access the required hardware. If you are not using the user “pi”, change the user at the end of the command accordingly.
Now enter the following command in the terminal:

sudo usermod -a -G spi,gpio,i2c pi
Then restart your Raspberry Pi with the following command:

sudo reboot
After the reboot, enter the following command into the terminal:

sudo raspi-config
There you can now activate SPI and I2C under 3 Interface Options so that you can use both interfaces.

After you have connected the display, you can execute a sample program with the following two commands:

cd ~/luma.examples/examples/sudo python3 demo.py -i spi

After you have connected the display, you can execute a sample program with the following two commands:
cd ~/luma.examples/examples/sudo python3 demo.py

ADDITIONAL INFORMATION

Our information and take-back obligations according to the Electrical and Electronic Equipment Act (ElektroG)

The symbol on electrical and electronic equipment:

This crossed-out dustbin means that electrical and electronic appliances do not belong in the household waste. You must return the old appliances to a collection point.  Before handing over waste batteries and accumulators that are not enclosed by waste equipment must be separated from it.

Return options:
As an end-user, you can return your old device (which essentially fulfills the same function as the new device purchased from us) free of charge for disposal when you purchase a new device. Small appliances with no external dimensions greater than 25 cm can be disposed of in normal household quantities independently of the pur­chase of a new appliance.
Possibility of return at our company location during opening hours: SIMAC Electronics GmbH, Pascalstr. 8, D-47506 Neukirchen-Vluyn, Germa­ny Possibility of return in your area:
We will send you a parcel stamp with which you can return the device to us free of charge. Please contact us by email at Service@joy- it.net or by telephone.
