Field Documentation

int(* sensors_poll_device_t::activate)(struct sensors_poll_device_t *dev, int handle, int enabled)

Activate/deactivate one sensor.

Parameters

handle	is the handle of the sensor to change.
enabled	set to 1 to enable, or 0 to disable the sensor.

struct hw_device_t sensors_poll_device_t::common

int(* sensors_poll_device_t::poll)(struct sensors_poll_device_t *dev, sensors_event_t *data, int count)

Returns an array of sensor data.

This function must block until events are available.

Returns: the number of events read on success, or -errno in case of an error. This function should never return 0 (no event).

Definition at line 467 of file sensors.h.

int(* sensors_poll_device_t::setDelay)(struct sensors_poll_device_t *dev, int handle, int64_t ns)

Set the delay between sensor events in nanoseconds for a given sensor.

If the requested value is less than sensor_t::minDelay, then it's silently clamped to sensor_t::minDelay unless sensor_t::minDelay is 0, in which case it is clamped to >= 1ms.
