it not very clear what the interval means. could you use
Time::kMicrosecondsPerSecond instead of 1000000? also it may make sense to
introduce
kInertialSensorSamplingFrequencyHz = 60;
kInertialSensorIntervalMicroseconds = Time::kMicrosecondsPerSecond /
kInertialSensorSamplingFrequencyHz;

Done.

same as above

[jdarpinian, 2014/09/25 22:36:18]

Done.
