Full-frame fade

Source: examples/full-frame-fade.ts

Builds a full Uint8Array(SLOT_COUNT) and fades it in over two seconds. write schedules the fade; it does not wait for the duration to elapse.

import { createSacnSource, SLOT_COUNT } from "@helioslx/core";
import { RecordingTransport } from "@helioslx/core/testing";

const source = createSacnSource({
  transport: new RecordingTransport(),
  ownsTransport: true,
});

try {
  const frame = new Uint8Array(SLOT_COUNT);
  frame[0] = 255;
  frame[1] = 128;
  frame[2] = 64;

  const snapshot = await source.universe(1).write(frame, {
    durationMs: 2_000,
  });

  console.info(
    `Scheduled fade for universe ${snapshot.universe} with ${snapshot.activeTransitions} active transitions.`,
  );
} finally {
  await source.close();
}
