Communicate and transfer files from and to MicroPython boards via REPL

Project description


Transfer files via Python REPL (Read Evaluate Print Loop). This tool was developed to transfer files from and to MicroPython boards.

This is yet an other tool, there are now several similar tools but not all have the same features.

Key features of this one:

  • detect serial ports and MicroPython boards.

  • run temporary scripts.

  • pull get files and directories from the target filesystem.

  • push files and directories on the target filesystem.

  • mount target as filesystem (FUSE).

  • --interactive mode (terminal).

  • set RTC

  • All of the above, and more, via the serial REPL connection to a MicroPython board.


Here is the output of python3 -m there --help:

usage: [-h] [-p PORT] [-b BAUDRATE] [--set-rtc]
                  [--reset-on-connect] [-c COMMAND] [-i] [--reset] [-u USER]
                  [-w PASSWORD] [-v] [--develop] [--timeit]
                  ACTION ...

Do stuff via the MicroPython REPL

optional arguments:
  -h, --help            show this help message and exit

port settings:
  -p PORT, --port PORT  set the serial port
  -b BAUDRATE, --baudrate BAUDRATE
                        set the baud rate

operations before running action:
  --set-rtc             set the RTC to "now" before command is executed
  --reset-on-connect    do a soft reset as first operation ( will not
                        be executed)

operations after running action:
  -c COMMAND, --command COMMAND
                        execute given code on target
  --command-timeout T   timeout in seconds for --command
  -i, --interactive     drop to interactive shell at the end
  --reset               do a soft reset on the end

  -u USER, --user USER  response to login prompt
  -w PASSWORD, --password PASSWORD
                        response to password prompt

  -v, --verbose         show diagnostic messages, repeat for more
  --develop             show tracebacks on errors (development of this tool)
  --timeit              measure command run time

  use " ACTION --help" for more on each sub-command

  ACTION                sub-command help
    detect              help locating a board
    run                 execute file contents on target
    ls                  list files
    hash                hash files
    cat                 print contents of one file
    pull                file(s) to copy from target
    push                file(s) to copy onto target
    rm                  remove files from target
    df                  Show filesystem information
    mount               Make target files accessible via FUSE
    rtc                 Read the real time clock (RTC)

The -c option executes the given string after running all the actions. The -i option enters a miniterm session at the end of all other actions.

The tool automatically selects a USB port for communication, it may take the wrong one if multiple USB serial devices are connected. In that case, use there detect to list all devices and then -p PORT to specify the port to use on the other calls.

Use python3 -m there <action> --help to get help on sub-commands.


This tool requires Python 3.

It depends on pySerial for communication and the mount function requires fusepy. Those dependencies are automatically installed when using pip, see installation notes in documentation.
