It simulates a sensor triggering an event through the nvs framework. The event is triggered by a write to its sysfs "on_ms" file. When the event is triggered, it also toggles the GPIO specified in its DT entry to turn on an LED. This can be used with a high speed camera to capture the event start time when doing latency measurements.
