// Common pattern: declare all the views in an object. This is absolutely not
// required, but adds clarity to the script.
let views = {
    // the view dispatcher auto-✨magically✨ remembers views as they are created
    loading: loadingView.make(),
    empty: emptyView.make(),
    demos: submenuView.makeWith({
        items: [
            "Hourglass screen",
            "Empty screen",
            "Exit app",
        ],
    }),
};

// go to different screens depending on what was selected
eventLoop.subscribe(views.demos.chosen, function (_sub, index, gui, eventLoop, views) {
    if (index === 0) {
        gui.viewDispatcher.switchTo(views.loading);
    } else if (index === 1) {
        gui.viewDispatcher.switchTo(views.empty);
    } else if (index === 2) {
        eventLoop.stop();
    }
}, gui, eventLoop, views);

// go to the demo chooser screen when the back key is pressed
eventLoop.subscribe(gui.viewDispatcher.navigation, function (_sub, _, gui, views) {
    gui.viewDispatcher.switchTo(views.demos);
}, gui, views);

// run UI
gui.viewDispatcher.switchTo(views.demos);

eventLoop.subscribe(timer, function(_subscription, _item, eventLoop) {
    print("Hello, World!");
    eventLoop.stop();
}, eventLoop); // notice this extra argument. we'll come back to this later

### Description
Configure serial port. Should be called before all other methods.
Automatically disables Expansion module service to prevent interference.

### Parameters

- Serial port name (`"usart"`, `"lpuart"`)
- Baudrate
- Optional framing configuration object (e.g. `{ dataBits: "8", parity: "even", stopBits: "1" }`):
  - `dataBits`: `"6"`, `"7"`, `"8"`, `"9"`
    - 6 data bits can only be selected when parity is enabled (even or odd)
    - 9 data bits can only be selected when parity is disabled (none)
  - `parity`: `"none"`, `"even"`, `"odd"`
  - `stopBits`: `"0.5"`, `"1"`, `"1.5"`, `"2"`
    - LPUART only supports whole stop bit lengths (i.e. 1 and 2 but not 0.5 and 1.5)

### Example

```js
// Configure LPUART port with baudrate = 115200
serial.setup("lpuart", 115200);
