A Python API For wiki.sipeed.com/m3axpi Pipeline
Project description
what this ?
This project is a Python implementation of ax-pipeline.
pip3 install ax-pipeline-api -U
Based on AX620A Debian11 system. Docs at wiki.sipeed.com/m3axpi
Python apis for pybind11 and ctypes are implemented here, but please do not mix them as there is only one screen and one camera.
-
pybind11 has a friendlier usage
-
ctypes have a more stable effect
new pybind11 code (1.0.9+)
It need update debian11(202202+) for pillow ImageFont(freetype). (
sudo apt install libxft-dev && pip3 uninstall pillow -y && pip3 install pillow --no-cache-dir -U)
The new API is still in an unstable state, so don't mind if you encounter strange bugs.
