About the Project

The Luma Matrix is a Workshop by ZHAW to play and create with coding. The center of the workshop is an 8 by 8 pixel matrix controlled with a micro:bit. Use the blocks from the extension to build whatever you have in mind. Draw images, show text, display the time, or even connect it to other Luma Matrices.

Use as an Extension

This repository can be added as an extension in MakeCode.

Initialize Matrix

The matrix must be initialized at the beginning of every program. There is a block for this:

lumaMatrix.initializeMatrix(135)

Example

The available blocks can display images and text, as well as control individual pixels.

lumaMatrix.initializeMatrix(135)
lumaMatrix.scrollText("LUMA MATRIX", 0xff00FF, 90)
lumaMatrix.showImage(lumaMatrix.matrix8x8(`
    . . . . . . . .
    . # # . . # # .
    . # # . . # # .
    . . . . . . . .
    # . . . . . . #
    . # . . . . # .
    . . # # # # . .
    . . . . . . . .
    `), 0xffff00)

Communication

radio.setGroup(25)
lumaMatrix.initializeMatrix(135)
lumaMatrix.scrollText("LUMA MATRIX", 0xff00FF, 90)
lumaMatrix.showImage(lumaMatrix.matrix8x8(`
    . . . . . . . .
    . # # . . # # .
    . # # . . # # .
    . . . . . . . .

    . # . . . . # .
    . . # # # # . .
    . . . . . . . .
    `), 0xffff00)

loops.everyInterval(5000, function() {
    lumaMatrix.sendImageWithColor(lumaMatrix.matrix8x8(`
    . . . . . . . .
    . # # . . # # .
    . # # . . # # .
    . . . . . . . .
    # . . . . . . #
    . # . . . . # .
    . . # # # # . .
    . . . . . . . .
    `), 0xffff00)
    basic.pause(300)
    lumaMatrix.sendImageWithColor(lumaMatrix.matrix8x8(`
    . . . . . . . .
    . # # . . # # .

    . . . . . . . .
    . . . . . . . .
    `), 0xffff00)
})

lumaMatrix.onReceivedMatrix(function(dataType: number, receivedBuffer: Buffer) {
    if (dataType == lumaMatrix.getDataType(lumaMatrix.eDataType.Bitmap)) {
        lumaMatrix.showImage(lumaMatrix.parseImage(receivedBuffer), lumaMatrix.parseBufferForColor(receivedBuffer))
    }
})
