A Blocks / JavaScript code editor for the micro:bit built on Microsoft MakeCode

micro:bit target for PXT

pxt-microbit is a Microsoft Programming Experience Toolkit (PXT) target that allows you to program a BBC micro:bit.

• pxt-microbit beta, v3.0.* requires

  • pxt-microbit#stable3.0
  • pxt#stable6.0.
  • pxt-common-packages#stable6.0.

• pxt-microbit v2.0.*, branch stable2.0, requires pxt v5.15.*. It is the servicing branch for live editor.

• pxt-microbit v1.* requires pxt v4.4, which is currently in the stable4.4 branch of pxt.

• pxt-microbit v0.* is in the v0 branch of this repository

• Try it live

Issue tracking

Please add an issue if you discover an (unreported) bug.

Developing new extensions

Authoring and testing of new extensions can be done directly from the web editor. See our documentation on how to get started. If you want to run the editor locally, keep reading.

Local server setup

The local server lets you to run the editor and serve the documentation from your own computer. It is meant for a single developer used and not designed to serve the editor to a large amount of users.

1. Install Node.js 8.9.4 or higher.
2. Clone this repository.

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

3. Install the PXT command line (add sudo for Mac/Linux shells).

npm install -g pxt

4. Install the pxt-microbit dependencies.

npm install

Go to the Running section.

Developer Setup

This is the typical setup used by the MakeCode team to work on the microbit.

1. Install Node.js 8.9.4 or higher.
2. Install Docker if you plan to build .cpp files.
3. Clone the pxt repository.

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

4. Install the dependencies of pxt and build it

npm install
npm run build
cd ..

5. Clone the pxt-common-packages repository

git clone https://github.com/microsoft/pxt-common-packages
cd pxt-common-packages
npm install

6. Link pxt-common-packages to pxt

npm link ../pxt
cd ..

7. Clone this repository.

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

8. Install the PXT command line (add sudo for Mac/Linux shells).

npm install -g pxt

9. Install the pxt-microbit dependencies.

npm install

10. Link pxt-microbit back to base pxt repo (add sudo for Mac/Linux shells). This step is only required if you intend to make changes to pxt and/or pxt-common-packages repos. If all you want is serve a local Makecode, you can skip this step.

npm link ../pxt
npm link ../pxt-common-packages

Note the above command assumes the folder structure of

       makecode
          |
  ----------------------------------
  |       |                        |
 pxt      pxt-common-packages  pxt-microbit

Running

Run this command from inside pxt-microbit 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 --local

If you want to speed up the build, you can use the rebundle option, which skips building and simply refreshes the target information

pxt serve --rebundle

Cleaning

Sometimes, your built folder might be in a bad state, clean it and try again.

pxt clean

Building with CODAL locally

The following commands force a local build using CODAL.

pxt buildtarget --local

To disable docker, run

export PXT_NODOCKER=1

If you are also modifiying CODAL, consider running pxt clean to ensure the proper branch is picked up.

Modifying DAL/CODAL locally

• follow instructions above until pxt serve
• open editor on localhost and create a project
• do export PXT_FORCE_LOCAL=1 PXT_RUNTIME_DEV=1 PXT_ASMDEBUG=1; you can add PXT_NODOCKER=1; pxt help has help on these
• find project folder under pxt-microbit/projects, typically pxt-microbit/projects/Untitled-42
• if you're going to modify .cpp files in PXT, replace "core": "*" in pxt.json with "core": "file:../../libs/core"; similarly "radio": "file:../../libs/radio" and "microphone": "file:../../libs/microphone"
• you can edit main.ts to change the PXT side of the program; you can also edit it from the localhost editor; note that Download in the localhost editor will produce different binary than command line, as it builds in the cloud and uses tagged version of CODAL
• in that folder run pxt build - this will clone codal somewhere under built/ (depends on build engine and docker)
• there can be an issue with exporting the variables i.e. PXT_FORCE, so including them in the build command can help solve issues sudo PXT_NODOCKER=1 PXT_ASMDEBUG=1 PXT_RUNTIME_DEV=1 PXT_DEBUG=1 PXT_FORCE_LOCAL=1 PXT_COMPILE_SWITCHES=csv---mbcodal pxt build
• if the target is not building, delete files in hexcache found in pxt-microbit/built/hexcache to force local build
• the built hex can be found in pxt-microbit/projects/<your project name>/built named binary.hex
• similarly, you can run pxt deploy (or just pxt which is the same) - it will build and copy to MICROBIT drive
• assuming the build folder is under built/codal, go to built/codal/libraries and run code *
• in git tab, checkout appropriate branches (they are all in detached head state to the way we tag releases)
• modify files, run pxt, see effects
• you can also run pxt gdb to debug; this requires openocd
• other commands using openocd are pxt dmesg which dumps DMESG(...) buffer and pxt heap which can be used to visualize PXT heap (and CODAL's one to some extent)

Updating dal.d.ts

cd libs/blocksprj
rm -rf built
PXT_FORCE_LOCAL=1 PXT_COMPILE_SWITCHES=csv---mbcodal pxt build
PXT_FORCE_LOCAL=1 PXT_COMPILE_SWITCHES=csv---mbcodal pxt builddaldts
mv dal.d.ts ../core

Updates

Make sure to pull changes from all repos regularly. More instructions are at https://github.com/Microsoft/pxt#running-a-target-from-localhost

Update playlists in markdown

To add a new playlist, add an entry in /playlists.json, and regenerate the markdown (see paragraph below). You'll now have a new markdown gallery file listing the videos which you can reference in /targetconfig.json.

Get a Google API key and store it in the GOOGLE_API_KEY environment variables (turn on data from the app).

pxt downloadplaylists

Repos

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

• https://github.com/Microsoft/pxt, the PXT framework
• https://github.com/Microsoft/pxt-common-packages, common APIs accross various MakeCode editors
• https://github.com/lancaster-university/microbit, basic wrapper around the DAL
• https://github.com/lancaster-university/microbit-dal

pxt-microbit's Issues

code not rendering on docs page

go to http://localhost:3232/lessons/digi-yoyo/activity

image of the issue...

when errors in code, run + compile doesn't work

when errors in code, students don't know an error exists.

• run should work
• compile should work

WIN10 APP - Show Code

When you set variable in blocks, then click show Code... the variable is automatically set as null

let item = null;
item = 0;

Excel - Charting

Why is serial only present in an isolated example of on radio received?

Serial is present on data received in this example

basic.forever(() => {
    radio.sendNumber(input.acceleration(Dimension.X))
})
radio.onDataReceived(() => {
    led.plotBarGraph(radio.receiveNumber(), 1023)
})

Serial is not present on data received in this example. Why is this the case?

let jumps = 0
basic.forever(() => {
    let acc = input.acceleration(Dimension.Y)
    if (acc > 2000) {
        jumps = jumps + 1;
        radio.sendNumber(jumps)
        basic.showLeds(`
            . . . . .
            . # . # .
            . . # . .
            # . . . #
            . # # # .
            `)
        basic.clearScreen()
    }
})
input.onButtonPressed(Button.A, () => {
    basic.showNumber(jumps)
})
input.onButtonPressed(Button.AB, () => {
    let jumps = 0
    basic.showNumber(jumps)
})
radio.onDataReceived(() => {
    basic.showNumber(radio.receiveNumber())
    led.stopAnimation()
})

music blocks - blocks to JS

music blocks - blocks to JS

1 in reference to the light beatbox lesson

http://localhost:3232/lessons/light-beatbox/activity

2 enter this code with blocks

let light = 0;
input.onButtonPressed(Button.A, () => {
    music.rest(music.beat(BeatFraction.Sixteenth));
    light = input.lightLevel();
    if (light < 25) {
        music.ringTone(music.noteFrequency(Note.C));
    }
    else {
        music.ringTone(music.noteFrequency(Note.A));
    }
});

3 press convert.

4 i would expect the code to be equal to the following when using ringTone using JS without Blocks

input.onButtonPressed(Button.A, () => {
    music.rest(BeatFraction.Sixteenth)
    let light = input.lightLevel()
    if (light < 25) {
        music.ringTone(Note.C)
    }
    else {
        music.ringTone(Note.C);
    }
})

4 however, the conversion is not 1:1. Am i missing something when using music with JS vs using music with blocks ?

create sprites does not work..

1 open KSF, click JS

2 type this code

let hero = game.createSprite(2, 2)
let food = game.createSprite(4, 4)
let ghost = game.createSprite(0, 0)

3 would expect for these sprites to appears on the simulator.

4 the error is shown in blocks too.. see example below

4 nothing appears when pressing run

1. open KSF, go to JS...

2 enter this code

basic.forever(() => {
    led.plotBarGraph(input.acceleration(Dimension.X), 1023);
});

3 it would be ideal to receive Excel data from a single micro:bit using acceleration, it doesn not appear possible.

global find/replace with <br / > tag

open vs code.

1 global find <br / > tags

2 global replace with amper sign

3 allow spacing for quiz and quiz answers (fix break tags)

is showAnimation a supported API?

see this example...

http://localhost:3232/lessons/rotation-animation/quiz

if not, we should think of a global find/replace for the replacement API

global search - broken links..

Can we make a global search for broken links?

just found this broken link from quiz to 'tutorial'...

http://localhost:3232/lessons/zoomer/quiz

we should also do a global change from /tutorial to /activity...

.../microbit/lessons/zoomer/tutorial 

should be...

led.setBrightness(255)
led.plotAll()

there is no difference in brightness

math.random incorrectly decompiled to blocks

We should reconsider -- or -- deprecate the difference of semantics between blocks and js.

code not rendering... catch the egg game

the code works in the simulator, but not rendering

open KSF, enter this in JS

let basketX = 2
let eggX = 2
let eggY = 0
basic.forever(() => {

        high_voltage = voltage;
    }
    else {
        led.plotBarGraph(voltage, higherLimit);
    }
