How to enable OLED display on Raspbian: [1]
1. Update your Pi and Install the required dependencies
sudo apt-get update sudo apt-get -y upgrade sudo apt-get -y install i2c-tools python3-smbus python-smbus sudo apt-get -y install python3-pip python3-pil sudo pip3 install --upgrade setuptools sudo pip3 install --upgrade adafruit-python-shell sudo pip3 install adafruit-circuitpython-ssd1306 sudo pip3 install pi-ina219 sudo pip3 show pi-ina219
2. Run the following command to check the oled i2c port
sudo i2cdetect -y 1
for X729, the I2C address is 0x3c
Please sure teh I2C is enable before this step, please refer to How to enable I2C
3. Installation
3.1 Download the required scripts
cd ~ git clone https://github.com/suptronics/oled.git cd oled
3.2 Install the Adafruit CircuitPython library
sudo python3 raspi-blinka.py
3.3 Answering Y and hitting Enter when reboot prompted. Then renavigate to the oled directly by entering:
cd oled
3.4 Run the script to test the display
sudo python3 x729.py
3.5 Run the script at Raspberry Pi boot
sudo crontab -e
3.6 Add a line at the end of the file that reads like this:
PS: we must toogle to the /home/pi/oled directory because .ttf files is required to locate in current directory,you can refer to x729.py source file, or you can also remove the 'cd /home/pi/oled &&' if you use the absolute path of the ttf file in the source code.
@reboot cd /home/pi/oled && python3 /home/pi/oled/x729.py &
Save and exit. In nano, you do that by hitting CTRL + X, answering Y and hitting Enter when prompted.
