Setup

Connect i2c display to Raspberry Pi

• 5V power (RPi) => VCC (Display)
• Ground (RPi) => GND (Display)
• SDA (RPi) => SDA (Display)
• SCL (RPi) => SCL (Display)

Enable i2c display

After display is connected turn Raspberry Pi on and perform next steps in order to activate display

# Install required packages
sudo apt install i2c-tools python-smbus

# Enable i2c interface
sudo raspi-config # Interfaceing Options > I2C > Activate

# Reboot
sudo reboot

# Check address of display
sudo i2cdetect -y 1
# It is probably 0x27, but if it's some other address, init display with it
