Hi @egomatic this looks like the drivers for the screen were not installed correctly.
Try repeating these steps:

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

I get:

pip3 install ~/e-Paper/RaspberryPi_JetsonNano/python/
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

For more information visit http://rptl.io/venv

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

sorry, i have no Idea what to do, how to use this virtual environment, .. can you help pls?

I had the same problem when I tried using newer Debian 12 based Raspberry Pi OS Lite bookworm but if you go back to bullseye(Debian 11) it'll work

In Raspberry Pi imager
