How to enable OLED display on Raspbian:
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
3. Installation
3.1 Download the required scripts
cd ~ pi@raspberrypi ~ $ git clone https://github.com/suptronics/oled.git cd oled
3.2 Install the Adafruit CircuitPython library
pi@raspberrypi:~/oled $ sudo python3 raspi-blinka.py
3.3 Answering Y and hitting Enter when reboot prompted. Then renavigate to the oled directly by entering:
pi@raspberrypi ~ $ cd oled
3.4 Run the script to test the display
pi@raspberrypi:~/oled $ sudo python3 x729.py
3.5 Run the script at Raspberry Pi boot
pi@raspberrypi:~/oled $ 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;
@reboot cd /home/pi/oled && python3 /home/pi/oled/x729.py &
