This target allow to program a BBC micro:bit using PXT (Microsoft Programming Experience Toolkit).

• Try it live

The local server allows to run the editor and the documentation from your computer.

The following commands are a 1-time setup after synching the repo on your machine.

• if not yet installed, install Node.js 4.4.5 or higher
• clone this repo to your computer and go in the project folder

git clone https://github.com/microsoft/pxt-microbit
cd pxt-microbit

• install the PXT command line (add sudo for Mac/Linux shells).

npm install -g pxt

• install the dependencies

npm install

Run this command to open a local web server (add sudo for Mac/Linux shells)

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 modify the .cpp files, turn on yotta compilation with the -yt flag (add sudo for Mac/Linux shells):

pxt serve -yt

To update your PXT version and make sure you're running the latest tools, run (add sudo for Mac/Linux shells)

pxt update

The build automatically runs the following:

• make sure the built-in packages compile
• pxt run in libs/lang-test* - this will run the test in command line runner; there is a number of asserts in both of these
• pxt testdir in tests - this makes sure all the files compile and generates .hex files
• run the TD->TS converter on a number of test scripts from microbit.co.uk and make sure the results compile

To test something on the device:

• do a pxt deploy in libs/lang-test* - they should show 1 or 2 on the screen (and not unhappy face)
• run pxt testdir in tests and deploy some of the hex files from tests/built

The lang-test0 source comes from the pxt-core package. It's also tested with pxt run there.
