Description

It would be great to have an inline assembler or a way to pass machine code (already precompiled).
Python is great but quite slow for many timing sensitive applications.
It would be also useful to add features on the fly.

I see two possible implementations:
The classic one asm("nop; nop;")
Or a byte array containing the code.

Code Size

Shouldn't be much.

Implementation

I hope the MicroPython maintainers or community will implement this feature

Code of Conduct

Yes, I agree
