2.2 Description of the Demo Modes

The following sections describe each demo mode in more detail.

2.2.1 Mode Off – Haptics Effect Sequences

Mode Off is a set of haptic sequences that combine a series of haptic effects. The two effects below show combinations of clicks and ramps.

2.2.2 Mode 4 – ERM Clicks

Mode 4 shows the difference in open-loop and closed-loop ERM clicks. In closed loop, the driver automatically overdrives and brakes the actuator. In open-loop, the waveform must be predefined with overdrive and braking. The image on the left shows a closed-loop waveform and the image on the right shows the same input waveform without closed-loop feedback enabled.

2.2.3 Mode 3 – LRA Clicks

Mode 3 shows what the waveforms look like with and without braking and how closed-loop and open-loop mode affects the acceleration profile. Figure 8 and Figure 9 demonstrate single-cycle clicks. In closed loop, the driver automatically tracks the resonant frequency, and overdrives and brakes the actuator. In open-loop, the waveform must be predefined with a static drive frequency, and overdrive and braking times. Figure 10 shows a closed-loop waveform (with overdrive and braking) while Figure 11 shows openloop mode that does not have overdrive or braking. Overdrive and braking allows the waveform to feel more crisp.

2.2.4 Mode 2 – Alerts and Scroll Wheel

Mode 2 showcases the advantages of the Smart Loop Architecture which includes auto-resonance tracking, automatic overdrive, and automatic braking.

The two images below show the difference in acceleration between LRA auto-resonance ON and LRA auto-resonance OFF. Notice that the acceleration is higher when driven at the resonant frequency. The auto-resonance ON waveform has 1.32 G of acceleration and the auto-resonance OFF waveform has

0.92 G of acceleration. The auto-resonance ON waveform has 43% more acceleration.

DRV2604L Demonstration Program

Figure 12. LRA Auto-Resonance ON Figure 13. LRA Auto-Resonance OFF

Waveform (Button 1) Waveform (Button 2)

The reason for higher acceleration can be seen in the acceleration versus frequency graph below. 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. With the Smart Loop auto-resonance feature, the DRV2604L dynamically tracks the exact resonant frequency to maximize the vibration force.

Button 4 uses a series of clicks to create a scroll wheel effect. See the oscilloscope capture in Figure 15.

Figure 15. LRA Scroll Wheel Effect Waveform (Button 4)

2.2.5 Mode 1 – Click Waveforms

Mode 1 shows the advantages and disadvantages of the click waveform in the different modes of operation. Button 1 plays the click waveform with braking in auto-resonance. Button 2 plays the click waveform with no braking in auto-resonance. It is apparent that braking allows the waveform to dampen faster so there is no excessive oscillations at the end of the waveform. Button 3 plays the click with braking but in open loop. Braking is not supported in open loop, thus there is no reverse operation of the actuator shown in the graph.

2.2.6 Mode 0 – Auto-Calibration

Auto-calibration is a DRV2604L-embedded routine that detects the characteristics and behavior of an actuator and adjusts the drive waveform automatically.

Perform auto-calibration using the following steps:

1. Connect an actuator to the green output terminal (OUT) or use the on-board actuators

2. For an ERM actuator, run the ERM auto-calibration by pressing button B1

3. For an LRA actuator, run the LRA auto-calibration by pressing button B2

4. Read the auto-calibration register values using I2C

5. Test using buttons B3 and B4

2.3 RAM Library Mode

Access the RAM library effects by holding the + button until the mode LEDs flash and the colored LEDs flash ONCE.

Once in Library Mode the DRV2604L loaded RAM 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 % - modulo operator

To change between ERM and LRA:

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

• B1 – Press to select ERM

• B2 – Press to select LRA

2. Then use the RAM effects as described above.

4.7 Analog Input

The analog input accepts an analog signal to control the envelope of the output waveform.

Hardware Configuration

Figure 23. Analog Input

Use the following steps to use analog input mode:

1. Apply an analog signal (not PWM) to the AUDIO jack on the left side of the board. The tip of the inserted male 3.5 mm jack is applied to the IN/TRIG pin of the DRV2604L. See Figure 23.

2. Enter Additional Hardware Modes.

3. Select Mode 5 (00101’b) using the increment mode button (+).

4. In Mode 5, choose button B1–B4, depending on the actuator and input coupling.

• B1 – AC Coupling – ERM

• B2 – DC Coupling – ERM

• B3 – AC Coupling – LRA

• B4 – DC Coupling – LRA

5. Enable the analog input signal.

5 Measurement and Analysis

The DRV2604L uses PWM modulation to create the output signal for both ERM and LRA actuators. To measure and observe the DRV2604L output waveform, connect an oscilloscope or other measurement equipment to the filtered output test points, OUT+ and OUT–.

Measurement and Analysis

The DRV2604L 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 on the left shows the DRV2604L unfiltered waveform and the image on the right shows a filtered version used for observation and measurement.

Figure 25. DRV2604L Unfiltered Waveform Figure 26. DRV2604L Filtered Waveform

www.ti.com

If the DRV2604LEVM-CT filter is not used, TI recommends using a 1st-order, low-pass filter with a cutoff between 1kHz and 3.5kHz . Below is a recommended output filter for use while measuring and characterizing the DRV2604L in the lab.
