PC python script to run mpremote commands

[PM-TPI]

So....

Code: Select all

from mpremote import main
main.main()

returns...
Connected to MicroPython at COM12
Use Ctrl-] to exit this shell


But how do I run say... the 'mpremoyte ls' command ?
main() takes 0 positional arguments... so how do I pass 'ls' ?

I don't want to use bash scripts.

Hello,

I'm using it this way

Code: Select all

  def _call_mpremote(self, args):
    args.insert(0, 'mpremote')
    proc = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
    try:
      out, err = proc.communicate(timeout=None if self._timeout in (None, 0) else self._timeout)
# etc.

where args are arguments of mpremote.

Can't we make calls to mpremote directly
without needing to go back out to OS

Maybe. I've tried and did not succeeded. IMHO mpremote is not intended to be called as a module and pyboard.py should be used instead. For my use case, the method described was sufficient.

Damien didn't go into any detail in using it as a module.

Thank you jahr... subprocess, learn something new everyday.

You could also just populate sys.argv and then call main.main()

mpremote is built on pyboard.py, and this is designed to be used as a module from your own scripts.
See https://docs.micropython.org/en/latest/ ... rd-library

You can use pyb.fs_ls(), however this will print out to stdout which is probably not what you want. It would be good to extend these libraries to support this use case.
