mpftp

mpftp is the board tool for MicroPython-compatible and CircuitPython-compatible boards: it moves files, runs code, opens the REPL, installs packages and flashes firmware, from VS Code, from a browser tab or from a terminal.

pip install -i https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ pydevices-mpftp

That installs the mpftp command and the browser interface (python -m mpftp). For VS Code, Cursor and other compatible editors, download mpftp-*.vsix from the latest release and run Extensions: Install from VSIX…. Install has the details.

You don't need a board to try it. mpftp can hold a desktop MicroPython interpreter open the same way it holds a board:

mpftp hold start --spawn micropython
mpftp hold ask -d micropython "import sys; print(sys.implementation.name, sys.implementation.version[:2])" --text
mpftp hold ask -d micropython "print(sum(range(10)))" --text
mpftp hold stop -d micropython

micropython (1, 30)
45

hold start and hold stop also print their status as JSON. -d micropython names the holder, in case a board is held too.

For a board, name its port instead: mpftp ls -d /dev/ttyACM0 /, or COM3 on Windows.

Code signing policy

The Windows installer will be signed. Free code signing provided by SignPath.io, certificate by SignPath Foundation. SignPath signs Windows only, so the Linux .deb is not signed. Who builds, reviews and approves each signed release, and what the app sends over the network, is in the code signing policy.
