ESP-DSP

[street-grease-coder]

There's an entire section of esp-dsp already implemented as a component, making things like kalman filter super easy to access, and I would guess better in performance than implementations in micropython.
Is there any option to include it micropython builds currently, and if no, would you consider implementing it?

There is a module that can be compiled into many micropython implementations, including ESP-32: ulab.
It is a (smallish) subset of numpy and scipy - it does have vector operations, linear algebra, FFT, etc .. see docs. It does not have filter design functions nor a kalman filter implementation.

Maybe ulab it self can take advantage of some of the functions in the ESP-DSP sdk.

This could be done as one or more dynamic native modules (.mpy), or as a user C module. So these features could be implemented separately from core MicroPython. The mentioned ulab is an example of a user C module for DSP type functionality. And https://github.com/emlearn/emlearn-micropython is an example of dynamic native modules, that has FFT, IIR filters etc.
