Still cannot figure out the issue

python3 ~/zero-btc-screen/main.py

Traceback (most recent call last):
  File "/home/pi/zero-btc-screen/main.py", line 60, in <module>
    main()

NameError: name 'epd2in13_V2' is not defined. Did you mean: 'Epd2in13v2'?

I'm using Waveshare e-Ink v4 with Raspberry Pi Zero W and Raspberry OS Lite installed Tried to modify config appropriately, but get undefined modules in any case.

Could you please dive into it? Thank you!

Based on the error message, it seems the display drivers are not installed. Could you try running the following commands and let me know how it went?

git clone https://github.com/waveshare/e-Paper.git ~/e-Paper
pip3 install ~/e-Paper/RaspberryPi_JetsonNano/python/
