How can I pass on the imports and definitions? This should work the same way it does in regular Python. The best way to solve this is to pass the pin as an argument when you call the subroutines in the other file. main.py: import driver p = machine.Pin(1, mode=machine.Pin.OUT) driver.do_stuff(p) dr...

python3 -m pip install mpr

mpr isn't a pypi package, so you won't be able to install it with pip.

It's still in development, and the PR hasn't been merged yet. As roberthh said, it's available at the in-progress PR here: https://github.com/micropython/micropyt ... 6375/files

What if I want to modify the file from flash with C? Which file could be useful for me?

Exactly the same -- mp_stream_rw

I'm currently using MicroPython to develop esp32 board. Now I need to read a file in flash in main.c. How could I do this? Could anybody show me an example? Thanks You can use mp_vfs_open (see extmod/vfs.h) to open the file which will return a stream object, that you can use mp_stream_rw (or mp_str...

I looked into this post before post, but i don't know how to use spi and i2c with this script. That script provides a way to use /dev/i2c from MicroPython. It's called SMBus but that's (mostly) just another name for I2C. But really, on a Raspberry Pi, you might just be better off using regular Pyth...

I would love to see more work done on this port but sadly it's extremely very bare bones. The idea was to do the "hard" bit (i.e. get it to boot) and then hopefully people would be able to contribute the various drivers and Python APIs but this hasn't happened yet... So I have some questions. 1. Are...

Freezing code will definitely help as it will no longer have to store the bytecode in RAM.

Can anyone confirm whether settting the USB parameter to "high speed" addresses this issue? Alternatively, is there a way to use the EMMC module to log locally and tranfer later? https://store.micropython.org/product/WBUS-EMMC Yes to both questions. High speed mode works on the SF3W, and the EMMC c...

Please see http://docs.micropython.org/en/latest/l ... tooth.html and https://github.com/micropython/micropyt ... /bluetooth

This is supported on ESP32 and STM32 (e.g. pyboard d)

See Damien's reply on that issue. Doesn't look like there's currently a workaround sorry...
