Usage

Wake up the controller

import { Lannooleaf } from 'lannooleaf_spi_controller';

const controller = new Lannooleaf();

controller.wake();

Note: Wake should only be called when lannooleaf is in idle state and is not configured, when calling wake when contoller is already initialized unexpected behaviour may apear.

Send other command to controller

import { Lanooleaf, Color, Graph } from 'lannooleaf_spi_controller';

const controller = new Lannooleaf();
await controller.Init();

const graph = new Graph();
await controller.GetAdjList(graph);

var allAddresses = Array.from(graph.map.keys());

// Set the first led of each connected leaf
for (const address of allAddresses) {
  await controller.SetLed(address, 0, new Color(255, 0, 0));
}

// Generate colorsting of 16 with random colors and send to specific unit
var colorString = Array(16).fill(new Color(Math.floor(Math.random() * 255), Math.floor(Math.random() * 255), Math.floor(Math.random() * 255)));
await controller.SetLedString(allAddresses[0], colorString);

await controller.Destroy();
