Abstract
Examples include systems and methods for adjusting interrupt timestamps associated with sensor measurement data. One method includes receiving from a sensor an interrupt signal, storing an interrupt timestamp corresponding to the interrupt signal, and determining expected sampling rates associated with the sensor. The method also includes determining a first minimal latency timestamp based on a comparison of one or more previously stored interrupt timestamps and the expected sampling rates, and determining a second minimal latency timestamp based on the interrupt timestamp, one or more previously stored interrupt timestamps, and the expected sampling rates. The method also includes determining an estimated sampling rate of the sensor based on the first and second minimal latency timestamps, and determining an adjusted interrupt timestamp corresponding to the interrupt signal based on the estimated sampling rate and the interrupt timestamp.
