Hello,
We are using the DRV2605L in our product, we decided to switch to an LRA requiring open-loop operation. We are only using RTP mode.
I am however having trouble to make it work properly. I switch to demo boards to make it easier to debug (2305 Adafruit) and I get some very surprising results:
- When using one of the demo board (Adafruit 2305), everything works as intended, I can drive the LRA in open-loop.
- when using a second demo board (still Adafruit 2305 but different physical board), with the same software, then the DRV2605L only runs in close-loop.
Any idea what could be the issue here?
Thank you in advance,
Rémi
