Detailed Description

CS40L26 Haptic Driver for LRA and VCM.

Enumeration Type Documentation

cs40l26_source

enum cs40l26_source

#include <cs40l26.h>

Wavetable sources for effects.

Enumerator
CS40L26_SOURCE_BUZ	Playback from the buzz library.

Function Documentation

cs40l26_configure_buzz()

int cs40l26_configure_buzz	(	const struct device *const	dev,
		const uint32_t	frequency,
		const uint8_t	level,
		const uint32_t	duration )

#include <cs40l26.h>

Configure ROM buzz for haptic playback.

With large amplitudes and insufficient power, it's possible to reach the current limit.

Parameters

[in]	dev	Pointer to the device structure for haptic device instance
[in]	frequency	Frequency of haptic effect in Hz (default: 0xA5)
[in]	level	Amplitude of haptic effect, where UINT8_MAX is 100% (default: 0x40)
[in]	duration	Playback duration in units of 4 milliseconds

Return values

0	if success
<0	if failed
