	Queue samples for replay.
void	pbl_accel_sim_flush (const struct pbl_accel *accel)
	Drop the queued samples, keeping the last one replayed latched.

	Report an event, as if the part detected it.

Detailed Description

Simulated accelerometer, replaying the samples and events it is fed.

Fed samples are replayed one per sampling interval, the last one being latched once the queue runs out: a watch lying still, face up, until the first one. The simulated part has no FIFO.

Macro Definition Documentation

PBL_ACCEL_SIM_QUEUE_SIZE

#define PBL_ACCEL_SIM_QUEUE_SIZE   256U

Number of samples the replay queue holds.

SIM_ACCEL

#define SIM_ACCEL   (&pbl_accel_sim)

The simulated accelerometer.

Function Documentation

pbl_accel_sim_feed()

size_t pbl_accel_sim_feed	(	const struct pbl_accel *	accel,
		const struct pbl_accel_sim_sample *	samples,
		size_t	count
	)

Queue samples for replay.

Samples that do not fit in the queue are dropped.

Parameters

accel	Device.
samples	Samples.
count	Number of samples.

Returns

Number of samples queued.

pbl_accel_sim_flush()

void pbl_accel_sim_flush

(

const struct pbl_accel *

accel

)

Drop the queued samples, keeping the last one replayed latched.

Parameters

accel

Device.

pbl_accel_sim_report_event()

void pbl_accel_sim_report_event	(	const struct pbl_accel *	accel,
		const struct pbl_accel_event *	event
	)

Report an event, as if the part detected it.

Dropped while detection of that event type is disabled, as on real hardware.

Parameters

accel	Device.
event	Event.
