<![CDATA[OpenIMU330 Accelerometer & Gyro timestamps]]>Hi,

is it possible to get (accurate) timestamps of the accelerometer/gyrometer measurements?
for now the IMU app runs in a loop and only collects+filters/applies calibration to data but I couldn't find any IMU timestamp.

some IMUs offer interrupt lines which may be used to timestamp them (using input capture timers) or have timestamps attached to their measurements -- is it possible to get any of these working with OpenIMU? (at least µs accuracy would be good)

Best Regards
Thomas
