Detailed Description

Driver operations.

Called with the device lock held. See the class functions for their semantics.

Field Documentation

get_max_num_samples

uint32_t(* pbl_accel_ops::get_max_num_samples) (const struct pbl_accel *accel)

Get the depth of the hardware FIFO.

get_sampling_interval

uint32_t(* pbl_accel_ops::get_sampling_interval) (const struct pbl_accel *accel)

Get the sampling interval.

init

int(* pbl_accel_ops::init) (const struct pbl_accel *accel)

Bring the hardware up.

Returns 0, -ENODEV if the part does not answer, or a negative errno.

peek

int(* pbl_accel_ops::peek) (const struct pbl_accel *accel, AccelDriverSample *sample)

Read the most recent sample.

set_double_tap_detection

int(* pbl_accel_ops::set_double_tap_detection) (const struct pbl_accel *accel, bool on)

Optional.

Enable or disable double tap detection.

set_num_samples

int(* pbl_accel_ops::set_num_samples) (const struct pbl_accel *accel, uint32_t num_samples)

Set the maximum number of samples to batch.

set_rotated

int(* pbl_accel_ops::set_rotated) (const struct pbl_accel *accel, bool rotated)

Optional.

Set whether the sensor is mounted rotated by 180 degrees.

set_sampling_interval

int(* pbl_accel_ops::set_sampling_interval) (const struct pbl_accel *accel, uint32_t interval_us, uint32_t *actual_us)

Set the sampling interval, returning the one used in actual_us.

set_shake_detection

int(* pbl_accel_ops::set_shake_detection) (const struct pbl_accel *accel, bool on)

Optional.

Enable or disable shake detection.

set_shake_sensitivity_high

int(* pbl_accel_ops::set_shake_sensitivity_high) (const struct pbl_accel *accel, bool high)

Optional.

Select high or normal shake sensitivity.

set_shake_sensitivity_percent

int(* pbl_accel_ops::set_shake_sensitivity_percent) (const struct pbl_accel *accel, uint8_t percent)

Optional.

Set the normal shake sensitivity, 0 to 100.
