Field Documentation

calibrate

int(* pbl_vibe_ops::calibrate) (const struct pbl_vibe *vibe, uint8_t *cali)

Optional.

Calibrate, setting cali to the value to persist.

init

int(* pbl_vibe_ops::init) (const struct pbl_vibe *vibe)

Bring the hardware up.

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

set_calibration

int(* pbl_vibe_ops::set_calibration) (const struct pbl_vibe *vibe, uint8_t cali)

Optional.

Apply a value set by calibrate.

start

int(* pbl_vibe_ops::start) (const struct pbl_vibe *vibe, int8_t strength)

Drive the motor at strength, starting it if stopped.

stop

int(* pbl_vibe_ops::stop) (const struct pbl_vibe *vibe)

Stop the motor.
