Detailed Description

DRV2605 Haptic Driver for ERM and LRA.

Macro Definition Documentation

DRV2605_WAVEFORM_SEQUENCER_MAX

#define DRV2605_WAVEFORM_SEQUENCER_MAX   8

#include <zephyr/drivers/haptics/drv2605.h>

Maximum number of waveforms that can be stored in the sequencer.

DRV2605_WAVEFORM_SEQUENCER_WAIT_MS

#define DRV2605_WAVEFORM_SEQUENCER_WAIT_MS

(

ms

)

#include <zephyr/drivers/haptics/drv2605.h>

Value:

(0x80 | ((ms) / 10))

Creates a wait/delay value for the waveform sequencer.

This macro generates a byte value that, when placed in the drv2605_rom_data::seq_regs array, instructs the DRV2605 playback engine to idle for a specified duration.

Parameters

ms	The desired delay in milliseconds (rounded down to the nearest 10ms). Valid range is 10 to 1270.

Returns

A byte literal representing the wait time for the sequencer.

Enumeration Type Documentation

drv2605_haptics_source

enum drv2605_haptics_source

#include <zephyr/drivers/haptics/drv2605.h>

Types of haptic signal sources.

This enumeration defines the different types of haptic signal sources supported by the DRV2605.

Enumerator
DRV2605_HAPTICS_SOURCE_ROM	Playback from the pre-programmed ROM library.
DRV2605_HAPTICS_SOURCE_RTP	Playback from Real-Time Playback (RTP) data stream.
DRV2605_HAPTICS_SOURCE_AUDIO	Playback is generated from an audio signal.
DRV2605_HAPTICS_SOURCE_PWM	Playback is driven by an external PWM signal.
DRV2605_HAPTICS_SOURCE_ANALOG	Playback is driven by an external analog signal.

drv2605_library

enum drv2605_library

#include <zephyr/drivers/haptics/drv2605.h>

Effect libraries.

This enumeration defines the different effect libraries that can be used with the DRV2605 when using ROM source. TouchSense 2220 libraries are for open-loop ERM motors, DRV2605_LIBRARY_LRA is to be used for closed-loop LRA motors.

Enumerator
