DRV2603EVM-CT Requirements

Xueqing,

I have moved your post to the TI Touch Forum on our E2E Community site to get answered by our technical experts on the DRV2603 Haptics Driver.  They should be able to cover your questions and get your answers shortly.

Thanks,
Brad

Xueqing,

Thanks for your interest in the DRV2603.  The DRV2603EVM-CT includes the DRV2603 auto-resonance LRA driver, an MSP430 microcontroller, and two actuators. 

1. The EVM will work right out of the box and will allow you to demo and evaluate the driver on the bench.  If you want to create custom functionality using the on-board MSP430, then you will need a free IDE (from TI.com), Hardware programmer and firmware.  I would recommend purchasing the MSP430 Launchpad. See the Wiki below.

2. You can control the frequency and vibration strength for DC motors (ERMs) and you can control the amplitude of a linear resonant actuator (LRA); however, you cannot control the frequency for LRAs.  Instead, for LRAs the DRV2603 automatically detects the resonant frequency of the actuator and outputs a signal at that frequency.  The input signal simply indicates the amplitude of the output. 

Thanks,

Hi Brian,

 Thanks so much for your information.

I believe the DRV2603 EVM can help with one task. 

Moreover, I am a postgraduate student. Ideally, we would like to develop a handheld evaluation kit with a touchscreen in order to study how users feel the different vibrations. I realise that there are three types of actuators attached into touchscreen devices(LRA/ERM/Piezo).

Could you recommend any other evaluation modules for piezo actuators??

many thanks

Xueqing,

Thanks for sharing your application information!  Sounds interesting!

For Piezo, I would recommend taking a look at the DRV8662.  This is a 200Vpp Piezo Haptics driver.

Thanks,
Brian

Brian,

I tried to order  DRV2603EVM-CT online,  but it's been out of stock for nearly one month.

Will you produce  this kit again? If not,   could you tell me the latest one that has similar functions with DRV2603EVM??

many thanks

Xueqing,

Thanks for contacting us!  Unfortunately I do not have any better news for you, the board will be delayed for 2-3 weeks.  The issue is our actuator supplier has delayed shipment of one of the components for the board. 

If you place an order now, it will be fulfilled as soon as more are available.  I expect 2-3 weeks lead time on these boards.  Sorry for the bad news.

Thanks,
Brian

Brian,

Thanks for your information. I will check it later and keep on searching the similar board.

best wishes

Hello Brian,

Thanks for your help. I have bought the DRV2603 and MSP430.

However, I wondered how to connect the MSP430  to the DRV2603 module??

many thanks
