    RE: Custom board RS232 communications issue

    1.The OpenIMU300RI is data output silent, you should give a package rate to the unit to output data, for instance send command via serial interface:
    update output rate to 10hz, 55 55 75 50 0C 04 00 00 00 0A 00 00 00 00 00 00 00 74 22
    or change output rate to 100Hz, 55 55 75 50 0C 04 00 00 00 64 00 00 00 00 00 00 00 67 8B

    RE: Why the factory don't do the magnetometer calibration before openimu300 unit release to customer? How to do the openimu300 unit magnetometer calibration?

    @Amin Hi Amin, you could send command to 300ZI unit via User uart interface(VG_AHRS, INS appication), and get the debug log from debug uart interface as below. As for the debug port, OpenIMU user could refer to UART debug port.

    RE: Magnetic alignment process does not terminate

    @Sylvain-Joyeux you should use VG_AHRS application and try again. the IMU application does not support Mag calibration with python driver.

    RE: Magnetic alignment process does not terminate

    Hi Sylvain Joyeux,
    I checked the OpenIMU330ZI with firmware version VG_AHRS 1.1.3, it work normally on mag align process from my side as below, please reset IMU and test. Note: please do keep connection with PC during the mag align process or it will be never finish in case of disconnected.

    RE: OpenIMU330BI 1PPS usage

    Hi PineTreeWild,
    It will take less than 10s to finish the sync with 1PPS in the begining.
    The sync process is that:

    • CPU detects sync pulse and measures it’s period with sub-microsecond precision

    • If period is within 0.01% of target value for few consecutive periods signal considered to be valid and system will sync to it.
