Using the DRV2605, is there any way to auto detect what kind of motor is attached, either LRA or ERM?

Hi Ara,

You can try doing this:

1. Run auto-calibration in ERM mode, if it passes it is an ERM, if it fails it is not an ERM.
2. Run auto-calibration in LRA mode, if it passes it is an LRA, if it fails it is not an LRA.
3. Otherwise the actuator is not connected or broken.

Thanks,
Brian
