natmod question : Idf component in natmod ?

[favnec5]

Hello,
Is it possible to insert esp-idf components in nadmod project ?
(https://github.com/micropython/micropython/tree/master/examples/natmod)

for example, to call esp_.... functions in the projet ?

In the Makefile for a native module, you can:

• Add things to the include path by adding to CFLAGS
• Add .a files to be linked by adding to MPY_LD_FLAGS (requires MicroPython 1.25 or later)

This can, in theory, be used to incorporate code from other projects, including that which refers to hardware functionality.
However, the native module is built entirely separately from the main firmware build. That means that you cannot share global variables etc. So functions from esp-idf that relies on this, will not work. In practice, this will likely exclude any esp-idf functions or component that interact with the esp-idf RTOS, for example. Only simple functions without such dependencies can be expected to work in a native module.

Can we add Micropython as a component in my own esp-idf project and use it their?

An option would be calling into Python, see https://github.com/orgs/micropython/discussions/17360 for some discussion of that

MicroPython can be used as part of a bigger program using the embedding. See the embed examples in the repository. It would be possible to create an esp-idf component around this.
