0.91 Inch OLED Display

Description

This display is made of 128x32 individual OLED pixels. It communicates with Raspberry pi or Arduino series products via I2C protocol. Compatible with most of MCU which support I2C protocol communication. There are mounting hole and female pin header on the PCB, so that you can fix it to Raspberry Pi with screws and nuts. It is compatible with Adafruit OLED liberary.

How to program it

For Raspberry Pi 4B

Make sure I2C function has been enabled by using "sudo raspi-config" command in terminal.
Open a terminal and Download demo code from: [ https://github.com/adafruit/Adafruit_Python_SSD1306 ]

sudo python -m pip install --upgrade pip setuptools wheel
git clone https://github.com/adafruit/Adafruit_Python_SSD1306.git
cd Adafruit_Python_SSD1306
sudo python setup.py install
pip install Adafruit-BBIO

Run example Demo:

cd examples/
python stats.py

Application Scenario

FAQ

Question: why does it not show anything that I've tried as your instruction？ *Answer: Please make sure you have already open your i2c function and you can use this command to detect whether it has been turned on already. *i2cdetect -y 1
