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


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 &
X729-9.png

Save and exit. In nano, you do that by hitting CTRL + X, answering Y and hitting Enter when prompted.
