Is there a C/C++ API for the NPU on the VIM4?

Is there a C/C++ API available for the NPU on the Khadas VIM4? I have found Python examples, such as those using the KSNN Python API, but haven’t encountered any native C/C++ examples.

Specifically, I’m looking for C/C++ demo applications. Any guidance or references to documentation would be greatly appreciated.

@amaoyake this repo is C++ demos. Check docs here: https://docs.khadas.com/products/sbc/vim4/npu/demos

Anyway how to do Realtime Text Recognition via Khadas IMX415 camera to Khadas VIM4 via Gstreamer, using C++ OpenCV? There are no demos for realtime text recognition, only the Densenet CTC demo, which inputs image instead of video
