DRV2510Q1EVM: Driver disabling after waveform playback

Michael Drummond

Part Number: DRV2510Q1EVM

I'm using the haptics control console with the DRV2510Q1. I get the expected result with the actuator when I'm in the Standard Drive tab in HCC. However, when I switch to the WaveBuilder and play a waveform, the waveform plays as expected but following this the DRV ON LED turns off. The Fault LED remains off and the INPUT ON LED is also off after the waveform is played. At this point only the 3.3V LED is on. I can not play another waveform until I toggle the Enable switch under the Standard Drive tab.

I've had a look at the schematic of the board and I see that the DRV-ON LED is connected directly to a pin on the MSP430. Immediately following the waveform the enable pin of the DRV2510 is being pulled down briefly before returning to high. Do you know why the MSP430 is disabling the DRV2510? I have a 12V power supply connected at J5.

I'm planning to connect my own microcontroller to the DRV2510 so I'm not dependent on the MSP430 on the board, but I'd like to know what is going on in case I need to factor something into the design.

Many thanks!

    Hi Michael,

    I don't think this is intended function from the GUI/MSP430 firmware. I just tested it and do see the same thing happening occasionally. 

    on this EVM the Enable pin is driven by the MSP430 as you pointed out, so this is just a quirk of the GUI/ firmware.

    You can try re-flashing the MSP430 firmware in HCC (Help -> firmware update), and reconnect the EVM to try and resolve the issue

    Hi Arthur,

    Thanks for your quick reply and trying it out. It's good to know it's not just my set up.

    I'll update the firmware and see if it does anything. I'm planning to feed in a PWM signal from a separate board anyway, so if it's a firmware issue I don't need to worry. If I run in to further issues or find out more I'll update this.

    Regards,

    Michael

    Hi Arthur,

    I tried re-flashing the firmware, but ran into an error.

    Now I can't connect with the MSP in HCC anymore. I assume the line "Mass Erase..." indicates that the firmware was removed from the MSP. Did I do something wrong with the update process? How do I get it back to a working state?

    Regards,

    Michael

    Hi Michael.

    the instructions in the window are complete, so if you followed them you didn't do anything wrong. Are you certain you selected the correct firmware "DRV2510Q1EVM_1p5.txt"

    the "BSL device DisConnected" is unexpected. this makes me think that something may have gone wrong.

    Regards,
