It’s probably not compiled in; you need to define MICROPY_PY_BTREE

Re: Early Board Init vs. Late Board Init
If there’s a clash in pin assignments why does it matter who runs first?

My board was micropython 1.9.4, but I compiled mpy-cross 1.10.
Now I compiled mpy-cross of version 1.9.4 and everything works as expected.

Re: mpy-cross on the raspberry pi (ValueError: incompatible .mpy file)
There’s 4 reasons why importing .mpy could fail if (header[0] != 'M' || header[1] != MPY_VERSION || header[2] != MPY_FEATURE_FLAGS || header[3] > mp_small_int_bits()) { mp_raise_ValueError("incompatible .mpy file"); } Basically the version - or compile options - of micropython that you’re running do...

Re: Understanding Inside of Micropython
There is no document about internals.
The documentation for uPy is not even up to date.
You’re gonna have to read the code.

Re: Is there another way than multi-threading to achieve this?
I am just experimenting, wanted to build a clone of Tetris and have music play at the same time as an exercise. I see that multithreading is not yes fully supported, so I was wondering if anyone had a suggestion of how to achieve this. The obvious way is to change the music, by replacing the time.s...

Re: Running two concurrent threads
right. but even if i do it that way i can only sample 1000 times per second, right? No. One thing you have to understand is documentation is terribly incomplete. The documentation says you can only do interrupts down to 1ms but the uPy source code shows you can do it much faster. ports/esp32/machin...
