    MakeCode Maker Actions Status

    This is an experimental code editor for maker boards - try it at

    Who is this for?

    This editor is meant for micro-controllers that are friendly to breadboarding. The editor is based on Microsoft MakeCode.

    Local Dev Server

    The local server lets you to run the editor and serve the documentation from your own computer.


    1. Install Node.js 8.9.4 or higher.
    2. Install Docker if you are going to edit any .cpp files.
    3. Clone the pxt repository.
    git clone
    cd pxt
    1. Install the dependencies of Microsoft/pxt and build it
    npm install
    npm run build
    cd ..
    1. Clone the Microsoft/pxt-common-packages repository
    git clone
    cd pxt-common-packages
    npm install
    cd ..
    1. Clone the Microsoft/pxt-maker repository
    git clone
    cd pxt-maker
    1. Install the PXT command line (add sudo for Mac/Linux shells).
    npm install -g pxt
    1. Install the pxt-maker dependencies.
    npm install
    1. Link pxt-maker back to base pxt repo (add sudo for Mac/Linux shells).
    rm -Rf node_modules/pxt-core
    rm -Rf node_modules/pxt-common-packages
    pxt link ../pxt
    pxt link ../pxt-common-packages

    If you want to know if your folders are link, run ls -l and it will indicate them.

    ls -l node_modules/

    Note the above command assumes the folder structure of

      |       |                        |
     pxt      pxt-common-packages  pxt-maker

    Refresh dal.d.ts files

    Whenever you make changes to the #defines in the .cpp files, you will have to refresh the dal.d.ts files. For that, run

    pxt builddaldts

    CODAL changes

    If you need to do changes to CODAL itself, follow these steps.

    • create a new project in the web editor, then close the web server. Select the hardware you want to work with.
    • using a command prompt, open the projects folder and find the subfolder with your new project
    • open the folder in Visual Studio Code
    code .
    • open pxt.json and edit the dependencies to use the file:... path instead of *
       dependencies: {
            "adafruit-metro-m0-express": "file:../../libs/adafruit-metro-m0-express"
    • from the command line, set the PXT_NODOCKER environment variable to 1
    export PXT_NODOCKER=1
    • run a local build that will create a CODAL checkout automatically. If you are missing tools, you will be notified by the build script.
    pxt build --local --force
    • go to the built/dockercodal folder and open all CODAL in a new Visual Studio Code instance
    cd built/dockercodal
    code libraries/*
    • go to the Git tab in VS Code, and change the branch of the CODAL repository to work on to master. You can create a new branch to start doing your work and pull requests.

    • to build CODAL directly, run built/codal

    • to rebuild your project from pxt, run pxt build --local --force from the project folder


    Run this command from inside pxt-maker to open a local web server

    pxt serve

    If the local server opens in the wrong browser, make sure to copy the URL containing the local token. Otherwise, the editor will not be able to load the projects.

    If you need to modify the .cpp files (and have installed yotta), enable yotta compilation using the --localbuild flag:

    pxt serve --localbuild


    Make sure to pull changes from all repos regularly. More instructions are at


    The pxt-maker target depends on several other repos. The main ones are:
