Detailed Description

ROM data configuration.

This structure contains configuration data for when the DRV2605 is using the internal ROM as the haptic source (DRV2605_HAPTICS_SOURCE_ROM).

Field Documentation

brake_time

uint8_t drv2605_rom_data::brake_time

Brake time offset.

A signed 8-bit value that adds a time offset to the braking portion of the waveform. The offset is brake_time * 5 ms.

See Table 13 of the DRV2605 datasheet.

library

enum drv2605_library drv2605_rom_data::library

Effect library to use for playback.

overdrive_time

uint8_t drv2605_rom_data::overdrive_time

Overdrive time offset.

A signed 8-bit value that adds a time offset to the overdrive portion of the waveform. The offset is overdrive_time * 5 ms.

See Table 10 of the DRV2605 datasheet.

seq_regs

uint8_t drv2605_rom_data::seq_regs[8]

Waveform sequencer contents.

This array contains the register values for the sequencer registers (0x04 to 0x0B). Each byte can describe either:

• A waveform identifier (1 to 123) from the selected library to be played.
• A wait time, if the MSB is set. The lower 7 bits are a multiple of 10 ms. Playback stops at the first zero entry.

See Table 8 of the DRV2605 datasheet.

sustain_neg_time

uint8_t drv2605_rom_data::sustain_neg_time

Sustain negative time offset.

A signed 8-bit value that adds a time offset to the negative sustain portion of the waveform. The offset is sustain_neg_time * 5 ms.

See Table 12 of the DRV2605 datasheet.

sustain_pos_time

uint8_t drv2605_rom_data::sustain_pos_time

Sustain positive time offset.

A signed 8-bit value that adds a time offset to the positive sustain portion of the waveform. The offset is sustain_pos_time * 5 ms.

See Table 11 of the DRV2605 datasheet.

trigger

enum drv2605_mode drv2605_rom_data::trigger

Mode of operation for triggering the ROM effects.
