DRV2605LEVM-CT: Can we operate open-loop on EVM

Part Number: DRV2605LEVM-CT

Hi,

Let me confirm about below.

Can we operate "open-loop" on DRV2605L-CT EVM when user use "LRA" ?

According to user's guide, user can use "open-loop" in demo mode when user use "ERM".

However, in case of LRA, it seems that user can not use "open-loop" by using "demo mode"

Is my understanding correct ?

If yes, when user want to operate "open-loop" w/ LRA, does user need to use "Haptics control console" ?

Best Regards,

    Hey Ryuuichi,

    If you want to use an LRA in open-loop mode, you need to use it in auto-resonance off mode. If you go to page 16 of the user guide, under binary counting modes, mode 5, you will find this info.

    However, if this mode does not work, we have been experiencing some problems with the firmware of this EVM, and we will be releasing a new one. If that is the case, then you ll have to wait for the new firmware to come out.

    Best regards,
    Marko
