HAPTICS-CONSOLE: No output with WaveformBuilder condition

NOBUO FUJIHARA

Part Number: HAPTICS-CONSOLE

Hi Champs,

My customer is using DRV2510EVM with Haptic Control Console Version 1.5.4.0.

It works when I use Standard Drive tag, but it doesn't when WaveBuilder is selected.

By pushing "START WAVEFORM" button, I could monitor expected waveform at IN+/IN- node of the EVM, but OUTA and OUTB stay zero.

Could you check and provide workaround?

Best regards,

    Hi Fujihara-san,

    What is the firmware version of your EVM? Please make sure to update the firmware to the latest version (v1.5)
    In previous firmware versions the signals coming from the MSP into DRV2510 in wavebuilder mode are in phase, thus they're eliminated by differential input. Latest firmware is working fine.
