Struct esp32_simple::gps::Sensor

pub struct Sensor<'a, T: Trigger> { /* private fields */ }

Represents a GPS sensor.

Type Parameters

• 'a - Lifetime of the sensor.
• T - The trigger type implementing the Trigger trait.

Implementations

impl<'a, T: Trigger> Sensor<'a, T>

pub fn new( notifier: Notifier<T>, trigger: &'static T, state: Arc<Mutex<State>>, uart: UartRxDriver<'a>, data: Arc<Mutex<Option<Reading>>>, ) -> Self

Creates a new GPS Sensor.

Arguments

• notifier - A notifier to send GPS data available events.
• trigger - The trigger to emit when a new reading is available.
• state - Shared on/off state controlling whether the sensor reads data.
• uart - UART receive driver connected to the GPS module.
• data - Shared storage for the latest GPS reading.

Returns

A new Sensor instance ready to poll.

Trait Implementations

impl<T: Trigger> Poller for Sensor<'_, T>

fn poll(&mut self) -> Result<!>

Continuously reads NMEA sentences from the UART and publishes GPS readings.

Skips reading when the shared state is off. When a valid RMC sentence is parsed, stores the reading in the shared data mutex and sends a notification.

Errors

Returns an error if UART reading, mutex locking, or notification fails.
