arduino-cli v0.37.0

Arduino-cli

A javascript wrapper over the arduino-cli tool

Works on Arduino-cli 0.3.1-alpha.preview

How to use

1. Install it with npm install -S arduino-cli or yarn add arduino-cli;
2. Require in the code import arduinoCli from 'arduino-cli';
3. Create an instance and pass the path to the installed arduino-cli and config:

   const cli = arduinoCli('/bin/arduino-cli', {
     directories: {
       user: '~/arduino-cli/sketches',
       data: '~/arduino-cli/data',
     },
   });

   It will create a config file for the arduino-cli in your OS temp directory and pass it to any command you'll call later.
4. Then you can run commands, like this:

   cli.version().then(console.log); // "0.2.1-alpha.preview"

API

All commands runs asynchronously, so methods return Promises.

version()

Returns the version of arduino-cli. Wraps arduino-cli version.

• Returns Promise<String>

dumpConfig()

Returns the current config of arduino-cli as a plain JS object. Wraps arduino-cli config dump.

• Returns Promise<Object>

updateConfig(newConfig)

Replaces old config with the new one.

Accepts:

• newConfig <Object> — Plain JS object representation of .cli-config.yml

• Returns <Object> with the new config

listConnectedBoards()

A wrapper with a custom extension over arduino-cli board list.

Custom extension may be removed in the future. See issue #45

Returns a plain JS object which describes boards connected through serial ports. Also, it extends boards' FQBN with cpu option from boards.txt if a board is identified (a package installed) and has some options. For example, Arduino Nano will be transformed into three items with a modified FQBN and name.

• Returns Promise<Array<ConnectedBoard>>

listInstalledBoards()

A wrapper with a custom extension over arduino-cli board listall.

Custom extension may be removed in the future. See issue #45

Returns a plain JS object with boards, whose packages are installed. Also, it extends boards' FQBN with cpu option from boards.txt if a board is identified (a package installed) and it has some options. For example, Arduino Nano will be transformed into three items with a modified FQBN and name.

• Returns Promise<Array<InstalledBoard>>

listAvailableBoards()

Wraps arduino-cli core uninstall packageName. Uninstalls the core and tools for the specified package.

Accepts:

• packageName <String> — A package identifier, like arduino:samd

• Returns Promise<String> — a log

core.updateIndex()

Wraps arduino-cli core update-index. Downloads the original package_index.json and additional package index files.

• Returns Promise<String> — a log

createSketch(sketchName)

Wraps arduino-cli sketch new sketchName. Creates an empty sketchName/sketchName.ino inside the sketchbook directory.

• Returns Promise<String> — a full path to the created .ino file

compile(onProgress, fqbn, sketchName, verbose)

Wraps arduino-cli compile. Compiles the sketch for the specified board.

Accepts:

• onProgress <Function> — A function that is called on new data in stdout
• fqbn <String> — A fully-qualified board name. Like arduino:avr:mega:cpu=atmega2560
• sketchName <String> — A name of the sketch in the sketchbook directory. It can contain sketch name or full path to the sketch.

• verbose <Boolean> — Verbose output. By default is false

• Returns Promise<String> with a log of the compilation process

upload(onProgress, port, fqbn, sketchName, verbose)

Wraps arduino-cli upload. Uploads the compiled sketch onto the board.
