Bug? Investigate why DMP data contains errors when logging at slow rates (~1Hz) #87

Closed PaulZC closed 1 year ago

Issue identified by @Uygarkuzuoglu here

The DMP Quat9 data contains errors when logging at slow rates - like 1Hz:

At 10Hz, the data is clean:

The DMP is running at 55Hz, so I wonder if the 1Hz sampling is causing the FIFO to overflow?

I suspect we need to use setDMPODRrate to decrease the data rate when logging at slow rates
