mpremote_config

mpremote configuration and script snippets that can be executed simply

Note that this configuration has a dependency on a pre-release fork of mpremote to make the mpremote configuration work on Windows at all, and to pass the location of the configuration file in the __file__ variable.

• config.py Adds a simple mechanism to create additional mpremote commands by just creating a my_command.py script in the ./snippets folder. These then can be executed by running mpremote my_command referencing a file my_command or in combination with additional commands mpremote mount . connect_wifi my_command

• adds COM4: .. COM30: to simplify connection to multiple boards (only when running on windows)

• adds all scripts in the snippets folder as commands

• list all commands and scripts using mpremote help

Setup

• install mpremote ( pre-release fork) pip install git+https://github.com/Josverl/mpremote.git@main#subdirectory=tools/mpremote

• locate the folder and file where mpremote looks for its configuration. this is briefly mentioned at : https://docs.micropython.org/en/latest/reference/mpremote.html#shortcuts the relevant code is in mpremote/main.py ( improved version below)

      # use $XDG_CONFIG_HOME, if on Windows use $APPDATA
    if os.name != "nt":
        path = os.getenv("XDG_CONFIG_HOME") or os.getenv("HOME")
        path = os.path.join(path, ".config") if path else None
    else:
        path = os.getenv("HOME") or os.getenv("APPDATA")

  On *nix the paths will be tried: <$XDG_CONFIG_HOME>/.config/config.py <$HOME>/.config on Windows the windows paths will be tried: <$env:HOME>\config.py <$env:APPDATA>\config.py

  Unfortunatly there is no indication what paths are tested or used.
  For troubleshooting you should add a line like: https://github.com/Josverl/mpremote/blob/291b219ebc753ec71b587dcbe9c591e382b86aef/tools/mpremote/mpremote/main.py#L345

• fork / clone or download this repro to the folder relevant to your OS and configuration

Examples

Get family / port information on a specific device mpremote get_port mpremote COM5 get_port

Scan WiFi mpremote wifi_scan using the first avaiable device (which just happens to have a WiFi connector)

Connect to Wifi ( SSID / pwrd are currently hardcoded in the script) mpremote wifi_connect

Creating scripts / cmdlets

Create a new .py file in the snippets folder

• if the first line of the file starts with a comment # or a double-quote " , then the first line is used as the help text to the cmdlet

• The entire script is read from disk, and added to mpremotes commands.

• if you need to pass parameters to a script this is possible. while there apparently is a way that mpremote allows for parameter intsertion , i have not been able to grok this yet. the currently simple workaround is the run 2 commands , first to set a variable and then in your script detect if that variable exists , and otherwise us a deafault value. (see the wipe_folder script for an example)
