Repository Details

Arduino Lab for MicroPython is an Integrated Development Environment (IDE) for MicroPython.

Arduino Lab for MicroPython

Arduino Lab for MicroPython is a lightweight editor for MicroPython programs, supporting connection with a board, code upload, file transfer, interactive REPL shell. This project is sponsored by Arduino, based on original work by Murilo Polese. This is an experimental pre-release software, please direct any questions only to Github issues.

Features

  • MicroPython's Read Eval Print Loop (REPL)
    • Enter paste mode
    • Enter raw repl
    • Software reset
  • File system management (Disk and MicroPython File System)
    • Create
    • Rename
    • Remove
    • Upload
    • Download
  • Text editor with Python syntax highlight
  • Code execution controls
    • Run what's on text editor
    • Stop (keyboard interrupt)
    • Soft reset

Technical

Arduino Lab for MicroPython is an Electron app that has its main purpose to communicate over serial with a microprocessor running MicroPython. All Electron code is at /index.js.

All operations over serial are abstracted and packaged on /micropython.js which is an attempt of porting pyboard.py. The port has its own repository but for the sake of simplicity and transparency, micropython.js is committed as source code.

The User Interface (UI) source code stays inside /ui folder and is completely independent of the Electron code.

The communication between interface and Electron app is accomplished by using the methods and events specified by /preload.js.

Folder structure

At the root of the repository you will find:

  • /.github: Github's workflow configuration.
  • /build_resources: Icons and other assets used during the build process.
  • /scripts: Scripts executed during the build process.
  • /ui: Available user interfaces.
  • /index.js: Main Electron code.
  • /preload.js: Creates Disk and Serial APIs on Electron's main process and exposes it to Electron's renderer process (context bridge).

Arduino UI

Default UI is a choo-choo app. It has pre-built dependencies so no build process is required for the interface.

The dependencies and source code are included manually in the /ui/arduino/index.html file.

The app is a standard choo-choo app and it has:

  • /ui/arduino/app.js: A router deciding which view to load.
  • /ui/arduino/components: HTML templates and components.
  • /ui/arduino/store.js: A "store" that handles events emitted by the views, change the app state and orchestrate re-rendering.
  • /ui/arduino/libs: Prebuilt dependencies.

It can be useful to learn more about Choo or the Elm Architecture.

Disk and Serial API

In order for the UI code to be independent of Electron code, there is an API defined at /preload.js that describes all the allowed operations.

There are 2 main operation "channels": Serial communication and local Filesystem operations. Both channels offer methods that always return promises and are used mostly through async/await.

While the serial communication is mediated by /micropython.js, the local filesystem operations are done through Electron's ipcRenderer calls. The handlers for these calls are defined at /index.js

Running Arduino Lab for MicroPython from source code

  1. Clone this repository: git clone https://github.com/arduino/lab-micropython-editor.git
  2. Navigate to repository folder: cd lab-micropython-editor
  3. Install dependencies: npm install
  4. Run dev mode: npm run dev

Some changes on the Electron code will require reopening the app but all UI changes will only require refreshing the window (ctrl-r/cmd-r).
