Quaternion Output

    While testing the sensor I attempted to move from Euler Angles to Quaternion output. So far I have failed to get anything other than straight zeros from the sensor, both in my arduino-based environment, and also in in the CHR Serial Interface Graph output.

    Is there something I am doing wrong? Do I necessarily need to set a broadcast timing for Quaternions in the Configuration rider in addition to checking the appropriate Data points in the Data rider?


    The Serial Interface data graphs update at 20 Hz even when data is not arriving. If the data it is trying to plot isn’t coming in over the serial port, it will plot whatever it last received. In this case (likely) zeroes, since it didn’t receive anything.

    Make sure that quaternion data is being transmitted in the configuration settings.


    got it, there was a second setting necessary to enable quaternions. setting a broadcast setting only is not sufficient.

    whats weird about the quaternion broadcast: it seems to only affect AB and not CD. Same goes for Euler and the PSI message.
