Expand description

A trait implemented by transports which support advanced edge-detection on GPIO pins. This trait allows monitoring a set of pins, and getting a stream of “events” (rising and falling edges with timestamps) for any change among the set.

Required Methods§

source

fn get_clock_nature(&self) -> Result<ClockNature>

source

fn monitoring_start( &self, pins: &[&dyn GpioPin] ) -> Result<MonitoringStartResponse>

Set up edge trigger detection on the given set of pins, transport will buffer the list internally, return the initial level of each of the given pins.

source

fn monitoring_read( &self, pins: &[&dyn GpioPin], continue_monitoring: bool ) -> Result<MonitoringReadResponse>

Retrieve list of events detected thus far, optionally stopping the possibly expensive edge detection. Buffer overrun will be reported as an Err, and result in the stopping of the edge detection irrespective of the parameter value.
