UiTimer Class

Package: GHIElectronics.Endpoint.UI
Namespace: GHIElectronics.Endpoint.UI

Thread-safe periodic callback that runs on the UI thread. The callback fires inside UI.Run's LVGL pump every periodMs milliseconds, so widget updates in it are safe (LVGL itself is single- threaded). Dispose cancels the timer. Create / SetPeriod / Dispose are safe from any thread; the body runs on the UI thread.

public sealed class UiTimer : IDisposable

Constructors
