2.2.4 Mode 2 – Alerts

Mode 2 showcases the advantages of the smart loop architecture, which includes auto-resonance tracking, automatic overdrive, and automatic braking.

Figure 9 and Figure 10 show the difference in acceleration when using LRA auto-resonance on and LRA

auto-resonance off. Notice that the acceleration is higher when driven at the resonant frequency. Also, notice the start and stop time of the acceleration are much quicker when using the overdrive and braking feature of the DRV2605L.

Acceleration (G)

Frequency (Hz)

DRV2605L Demonstration Program

The reason for higher acceleration can be seen in Figure 11. The LRA has a very-narrow operating frequency range due to the properties of a spring-mass system. Furthermore, the resonance frequency drifts over various conditions such as temperature and drive voltage (the effects shown in Figure 11). With the smart loop auto-resonance feature, the DRV2605L dynamically tracks the exact resonant frequency to maximize the vibration force.

Figure 11. LRA Acceleration versus Frequency over Output Voltage

Figure 12 and Figure 13 show the difference between an ERM with automatic closed-loop overdrive and

braking, and the open-loop library waveform with a predefined overdrive period. The closed-loop version starts and stops the actuator perfectly and does not drive too long or too short. Automatic overdrive and braking simplify the design of haptic effects by eliminating the tuning time for actuator startup and stop.

2.2.5 Mode 1 – Waveform Matching Game

Mode 1 is a game that incorporates the various LRA effects. This can be used to demonstrate haptics in a real application.

To begin playing Matching:

1. Press any of the large effect buttons.

2. The game then counts down.

3. Once the countdown completes, a waveform will play from the LRA and the user must match that

given waveform from the given options list before going to the next waveform match.

• B1 - Play/repeat selected waveform from the options list

• B2 - Cycle through the waveforms in the options list to choose from

• B3 - Selects the guessed waveform (B1) as answer

• B4 - Play/repeat the given waveform

4. After each successfully successful match, the board will buzz from the LRA and count down to the next

given waveform. If the user selects incorrectly, then the ERM will buzz and the game is over. If the user matches all of the given waveforms, the LEDs will scroll and flash twice.

2.2.6 Mode 0 – Audio-to-Haptics

Audio-to-haptics is a unique feature that converts an audio signal to haptics. Take audio from music, games, or movies and automatically create haptic effects.

Buttons B1 to B4 perform the following actions:

• Button 1 – Audio-to-haptics using ERM

• Button 2 – Audio-to-haptics using LRA

• Button 3 – Switch to internal trigger and play library click effect

• Button 4 – Switch to internal trigger and play library buzz effect To use this mode:

1. Connect an audio source to the audio jack on the left side of the board. The tip of the audio connector

is applied to the input of the DRV2605L.

2. Press button 1 which enables audio-to-haptics using the on-board ERM

3. Decrease the volume of the audio source, if the ERM is constantly vibrating, or increase the volume, if

the ERM is not vibrating at all.

4. Feel the haptic vibrations as the audio plays.

5. Press button 2 which enables audio-to-haptics using the on-board LRA.

6. Decrease the volume of the audio source if the LRA is constantly vibrating or increase the volume if

the LRA is not vibrating at all.

7. Feel the haptic vibrations as the audio plays.

8. Press button 3 or 4 to trigger a click or buzz during audio-to-haptics playback.

2.3 ROM Library Mode

ROM library effects can be accessed by holding the "+" button until the mode LEDs flash and colored LEDs flash once.

Once in "Library Mode," the DRV2605L embedded ROM effects can be accessed in sequential order. For example, with all mode LEDs off, B1 is waveform 1, B2 is waveform 2, and so on. Then when mode LED M0 is on, B1 is waveform 5, B2 is waveform 6, and so on.

The equations for calculating the mode and button of an effect are:

Mode = RoundDown([Effect No.] / 4) Button = ([Effect No.] - 1) % 4 + 1

% - is the modulo operator

To change between the 5 ERM libraries and the Johnson Electric (JE) ROM Library:

1. Select mode 31 (11111'b) using the "+" or "–" buttons.

• B1 – Press repeatedly to access ROM libraries 1 through 5 and the JE ROM library. The current library flashes on the mode LEDs

• B2 – Press to select the LRA ROM library

2. Then use the ROM effects as described previously Each ERM library was designed for specific actuator behavior. Table 3 describes the actuator properties

that are best suited for each library. Note that the rated and overdrive voltages can be changed using the rated and overdrive clamp registers in the DRV2605L. The most important parameters to characterize with your actuator are the rise and brake times.

4.7 Audio-to-Haptics Input

The DRV2605L audio-to-haptics feature converts an audio signal to a corresponding haptics waveform. This can be used to simulate bass in music, or use the audio track of a game to produce haptic effects.

To use audio-to-haptics:

1. Apply an analog line-out audio signal (not PWM) to the AUDIO jack on the left side of the board. The tip of the inserted male audio plug is applied to the IN/TRIG pin of the DRV2605L. See Figure 21.

www.ti.com

Figure 21. Audio-to-Haptics Input

NOTE: To get the best performance using a headphone out, the user may need to adjust the

volume, so that the input signal is near, but does not exceed 1.8 V

2. In demo mode, select mode 0 (00001’b) using the increment mode button (“+”).

3. In mode 0, press either button B1 or B2 to enable the DRV2605L audio-to-haptics. Buttons B3 and B4 switch to internal trigger mode, play a ROM library effect, and then switch back to audio-to-haptics mode.

• B1 – Audio-to-haptics using ERM

• B2 – Audio-to-haptics using LRA

• B3 – Switch to internal trigger and play library click effect

• B4 – Switch to internal trigger and play library buzz effect

4. Play music and feel the vibrations of the actuator.

NOTE: Some audio signals are too large or too small and the volume must be adjusted. Adjust

DRV2605L ERM and LRA Haptic Driver Evaluation Kit SLOU389A–May 2014–Revised June 2014

appropriately so that the maximum input voltage is 1.8 V and the bass of the input signal can be felt on the actuator. The audio input minimum and maximum thresholds can be adjusted using I2C. See the datasheet for more details.

5 Measurement and Analysis

The DRV2605L uses PWM modulation to create the output signal for both ERM and LRA actuators. To measure and observe the DRV2605L output waveform, connect an oscilloscope or other measurement equipment to the filtered output test points, “OUT+” and “OUT–".

Figure 22. Terminal Block and Test Points

The DRV2605L drives LRA and ERM actuators using a 20-kHz PWM modulated waveform, but only the frequencies around the LRA resonant frequency, or the ERM DC drive voltage, are relevant to the haptic actuator vibration. The higher frequency switching content does not contribute to the vibration strength of the actuator and can make it difficult to interpret the modulated output waveform on an oscilloscope. The oscilloscope image Figure 23 shows the DRV2605L unfiltered waveform and Figure 24 shows a filtered version used for observation and measurement.

Measurement and Analysis

Figure 23. DRV2605L Unfiltered Waveform Figure 24. DRV2605L Filtered Waveform

If the DRV2605LEVM-CT filter is not used, TI recommends using a first-order, low-pass filter with a cutoff between 1 and 3.5 kHz. Figure 25 shows a recommended output filter for use while measuring and characterizing the DRV2605L in the lab.
