Part Number: DRV2625
We measure I2C SDA DRV2625 send to MCU(nRF52840) and there is two items out of MCU spec.(tHD;DAT and tHD;STA), data, spec. and waveform as below
Can you tuning it? Or any thing we need check (layout, etc..)
I am going to look little bit more into the I2C timing standards for these haptic drivers, but in the meanwhile can you provide the exact datasheet these specifications were drawn from as I had a hard time finding anything with details that refers to the timing of the processor you are using or any timing diagram that would go with it.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

After searching more I was able to understand more that your recording is reading times that are out of spec of what your processor's datasheet reads. There is no tuning method associated with the DRV2625's I2C interface, all of it's timing control comes from the master device. Possibly look at the application section starting on page 59 on the DRV2625 Datasheet to ensure you are properly connecting the device to your processor with the proper pull-up resistors.
If that does not work see if you have the same problem with other I2C interface based devices if possible.
