1.1 Evaluation Module Operating Parameters

The following table lists the operating conditions for the DRV2603 on the evaluation module.

Parameter Specification

Supply voltage range 2.5V to 5.2V

Power-supply Current Rating 400mA

External PWM Voltage, V

PWM

(optional) 1.8V to V

1.2 Quick Start Board Setup

The DRV2603EVM-CT firmware contains haptic effects which showcase the features and benefits of the

DRV2603. Follow the instructions below to begin the demo.

1. Out of the box, the jumpers are set to begin demo mode using USB power. The default jumper settings

can be found in the table below.

Jumper Default Position Description

JP1 Shorted Connect MSP430 PWM output to DRV2603 PWM input

JP2 Shorted 3.3V reference for I

JP3, JP4 Shorted Connect on-board actuators to DRV2603

MSP USB to MSP Select USB (5V) or VBAT power for the MSP430

DRV USB to DRV Select USB (5V) or VBAT power for the DRV2603

2. Connect the included mini-USB cable to the USB connector on the DRV2603EVM-CT board.

3. Connect the other end of the USB cable to an available USB port on a computer, USB charger, or USB

battery pack.

4. If the board is powered correctly the four colored LEDs will light up, the four mode LEDs will flash, and

the LRA and ERM will play an effect, indicating the board has been successfully initialized.

DRV2603 Demonstration Program

2 DRV2603 Demonstration Program

The DRV2603EVM-CT demo contains haptic effects which showcase the features and benefits of the

DRV2603. The sections below provide a detailed description of the included effects.

2.1 Modes and Effects Table

The effects preloaded on the DRV2603EVM-CT are listed in Table 1. The modes are selected using the

“+” and “–“ mode buttons in the center of the board. The current mode can be identified by the white LEDs

directly above the mode buttons. Buttons B1-B4 trigger the effects listed in the description column and will

change based on the selected mode.

2.2 Description of the Modes

The modes above were created to showcase various benefits of the DRV2603. See the description of

each mode below for more details.

2.2.1 Mode 0 – Ramp and Fade Waveforms

Mode 0 is ramp effects which demonstrate transitional effect capabilities of both LRAs and ERMs.

2.2.2 Mode 1 – Buzz and Alerts

Mode 1 demonstrates an LRA with auto-resonance on, an LRA with auto-resonance off, and an ERM.

Compare the difference in strength between the LRA with and without auto-resonance.

Figure 2 and Figure 3 compare the acceleration (in blue) between a driver without auto-resonance

detection and a driver with auto-resonance detection.

2.2.3 Mode 2 – LRA Clicks

Mode 2 showcases LRA clicks and double clicks. Notice the difference in length of the click with braking

and without braking. Then compare the double clicks and notice the event separation is only possible with

braking.

Figure 4 and Figure 5 show the difference between a click with braking and a click without braking. Notice

the acceleration (in blue) is much longer when braking is not applied.

2.2.4 Mode 3 – User Interface Effects

Mode 3 showcases LRA user interface effects.

1. Button 1 – Basic click effect

2. Button 2 – Click and Release effect – when holding the board press this button. The button will click

when pressed down and bump when released giving a full button effect.

3. Button 3 – Double tick effect – the double tick effect can be used for a backspace key or some other

special function key.

4. Button 4 – Scroll wheel effect – press this button while holding the board and feel the scroll-like effect

imitating a flick or scroll gesture.
