The (default) implementation for the real I2C powered LED board.

The board can be set using application configuration, however it is already the default:

config :bright_pi, board: BrightPi.Board

It can be started explicitly or via the preferred BrightPi.board/0 helper function.

defmodule MyApp.Application do
  use Application

  @impl true
  def start(_type, _args) do
    children = [
      BrightPi.Board, # explicit
      BrightPi.board() # preferred
    ]

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
end
