Blinkenlights Polychrome light and sound installation in Mildenberg, Germany, 2023

## Contributing Content

There are several ways to contribute to polychrome.

1. Submit an animation in the WebP format with the dimensions `242x8`. WebP animations go into [`octopus/priv/webp`](octopus/priv/webp).
2. Write an application in elixir to generate dynamic content. See our [example app](octopus/lib/octopus/apps/sample_app.ex).
3. Write a standalone program that sends Protobuf packets over UDP. See our [protobuf schema](protobuf/schema.proto).

Please send us pull requests!

## Architecture

Protobuf is used everywhere as the wire format. All messages are wrapped in the `Packet` message to ensure save decoding. See the [schema](./protobuf/schema.proto) for more details.

### Data flow for pixel and sound outputs

```mermaid
flowchart LR
  external_1[External Source] --> |UDP| udp_server_1
  external_2[External Source] --> |UDP| udp_server_2

subgraph Octopus

udp_server_1["Octopus.UDPServer [Port 2342]"] --> mixer
  udp_server_2["Octopus.UDPServer [Port 2343]"] --> mixer

app_1[Octopus.Apps.Foo] --> mixer
  app_2[Octopus.Apps.Baa] --> mixer

mixer["Octopus.Mixer"]-->broadcast[Octopus.Broadcaster]
  mixer --> |pubsub| manager[OctobusWeb.ManagerLive]

end

subgraph "Blinkenled panel (10x)"
  broadcast-->|UDP Broadcast|esp32[ESP32]
  esp32-->LEDS
  end

broadcast --> |UDP Broadcast| sim
  sim[Simulator]-->|live_view| live[HTML]

subgraph "Beak (sound)"
  broadcast --> |UDP Broadcast| beak
  beak--> Speakers
  end
```

### Data flow for input events

subgraph Octopus

input_adapter[Octopus.InputAdapter] --> mixer["Octopus.Mixer"]
  manager[OctobusWeb.ManagerLive] --> mixer

  mixer --> udp_server_2["Octopus.UDPServer [Port 2343]"]
  mixer --> app_1[Octopus.Apps.Foo]
  mixer --> app_2[Octopus.Apps.Baa]

end

udp_server_1 --> |UDP| external_1[External Source]
  udp_server_2 --> |UDP| external_2[External Source]
