mpbridge 1.4.0

File System Bridge to facilitate working with files on Micropython devices

📂 MPBridge

CLI tool to synchronise and manage files on a MicroPython running device.

📥 Installation

mpbridge must be installed with sudo or administrator level of permission in order to be accessible from terminal:

• Windows : Open cmd.exe or powershell.exe as administrator and run pip install -U mpbridge.
• Linux / MacOS : Run sudo pip install -U mpbridge.

🔎 How to use

You can use mpbridge in several ways based on your needs:

⚜️ Bridge Mode

• Run mpbridge bridge [PORT].
• This mode copies all files and folders from your MicroPython board into a temporary directory on your local device and listens for any filesystem events on local directory to apply them on your board. It keeps raw repl open, so you cannot use serial port in other applications simultaneously.

⚜️ Sync Directory

• Run mpbridge sync [PORT] [DIR_PARH].
• This command syncs a specified local directory with a MicroPython board. The sync process will push all modified files and folders into board and also pull changes from board and exits.
• If a conflict occurs, mpbridge will choose the local version of file automatically and overwrites it on connected board.

⚜️ Development Mode

• Run mpbridge dev [PORT] [DIR_PARH].
• This mode repeats a loop of tasks in specified directory on MicroPython device as below:
  • Sync → Prompt to enter REPL → Clean Sync → Start MicroPython REPL
• You can also disable prompt with --no-prompt option to speed things:
  • Clean Sync → Start MicroPython REPL
• This mode is useful when you keep switching between different tools to flash and run new codes repeatedly. You can specify your project directory as DIR_PATH and mpbridge will take care of changes when you are developing your project in your desired IDE. You can switch to MicroPython REPL anytime you wish to run the updated code on your board.
• Default to current path of terminal if not set the DIR_PATH.
• Automatic reset before entering MicroPython REPL can be enabled with --auto-reset option which can be set to soft (soft reset) or hard (hard reset).

⚜️ Delete all files

• Run mpbridge clear [PORT].
• This command deletes all files and directories from MicroPython board and exits.

⚜️ List all connected devices

• Run mpbridge list.
• This command lists all connected devices.

Note : [PORT] can be the full port path or one of the short forms below :

• c[n] for COM[n] (c3 is equal to COM3).
• u[n] for /dev/ttyUSB[n] (u3 is equal to /dev/ttyUSB3).
• a[n] for /dev/ttyACM[n] (a3 is equal to /dev/ttyACM3).

👀 Ignore files

You can inform mpbridge to ignore syncing specific files or directories. This is useful when you don't want to sync some directories like .git/ or venv/ with your board. To use this feature create a file named mpbridge.ignore in your project directory and specify list of files and directories:

.git/
venv/
tests/test_1.py
tests/test_2.py

• mpbridge.ignore syntax is not as same as .gitignore files.
• At this time mpbridge.ignore only supports specifying file and directory paths directly.
• You should add a slash at the end of directory names: dir1/.
• Performing sync with --dry-run flag can be helpful for debugging your ignore files.
