Pixoo Soup

Display a soup of pixels on your Divoom Pixoo. Should work on other Divoom devices as well.

This library uses a lot of code from https://github.com/RomRider/node-divoom-timebox-evo .

Usage

npm i pixoo-soup

import { display, connect, sleep } from "pixoo-soup";

async function displayRunningPixel(deviceAddress) {
  // Connect
  const connection = await connect(deviceAddress);

  const colors = ["000000", "00ff00"]; // array containing colors
  
  for (let i=0;i<256;i++) {
    const pixels = new Array(256).fill(0); // 256 length, color index references

    // set the pixel at i to color 1 (00ff00)
    pixels[i] = 1;
  
    // Display
    await display({ colors, pixels }, (buffer) => connection.write(buffer));

    // Give the pixoo some time to catch up
    await sleep(20);
  }

  // disconnect
  connection.close();
}


export function sleep(timeoutMs) {
  return new Promise((resolve) => setTimeout(resolve, timeoutMs));
}

displayRunningPixel(process.argv[2])
  .then(() => console.log("Hope you had fun with the pixel soup show!"));

API

async display({ colors, pixels }, writeBufferFn)

Displays the image object containing a colors and pixels fields on the Pixoo using the writeBufferFn.

Buffer[] toImageBuffers({ colors, pixels })

Low level function to transform the image object argument containing colors and pixels fields to a buffer array that can be sent to a Pixoo device via bluetooth.

connect(address)

Establishes a blootooth connection and returns a connection object to write buffers and to close the connection.

{
  async write(buffer) {}
  close() {}
}
