# 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

```bash

npm i pixoo-soup

```

```js

import { display, connect } 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();

}

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.

```js

{

  async write(buffer) {}

  close() {}

}

```
