    BMA400 synchronisation with external sensor

    Hi,

    i would like to use the BMA400 for a project i'm working on but i need to syncronize the accelerometer values with an external sensor.

    The sampling frequency for the external sensor is 100 Hz and i would like to keep the two sample (BMA400 sample and external sensor) within a couple of ms.  

    The external sensor has an internal clock for the sampling and an internal fifo that i would like to use to reduce power consumption.

    What strategy do you reccomend?

    Hi,

    Maybe use BMA400 in FIFO mode and read the timestamp.

    You could make software intepolation to align time with another sensor.
