Has anyone managed to use a mini oled screen for i2c-4 using Python, with a 3w radxa? Can you please contact me? Another thing, how can it be that I install libraries with pip or with ./**.sh and when I import them into python it tells me that the library does not exist? Has anyone managed to use it with mraa, or luma.core with i2c-4, activating it with rsetup, in python? Thanks, share the code that worked and explain steps like pip install luma.core, add to the path # Add your exports and aliases here export PYTHONPATH=$PYTHONPATH:/path/to/your/site-packages # Other aliases or configurations alias ll=‘ls -la’ Please put the installation path, necessary installed libs and functional example, thank you.
Use i2c in python, mini oled example
I have already gotten it to work by following these steps.
ls /dev/i2c-*
sudo apt-get install i2c-tools
sudo i2cdetect -y number # my case number 4
pip install luma.core
pip install luma.oled
pip install smbus2
pip install Pillow
Git clone https://github.com/Jodels2002/Rock5b_SSD1308.git 28
For some reason that I don’t know, only if I run the script in the folder where I installed pip install luma.oled the scripts find luma.core
