Dear support team,
Can you please let me know what is the external crystal connected to stm32f405? The frequency please?
Best regards,
Amin.

@Dong-xiaoguang said in AHRS Algorithm:
Kalman gain should be calculated separately for position, velocity and attitude.
Dear Dong,
the method you mention is for INS , what about for AHRS?
are position and velocity required for AHRS too or are those for INS specifically?
Best Regards
Amin
Hello, does AHRS/VG dynamic attitude app also using 16 state EKF ? or need to less state ?
Best Regards

Hi,
I need source code of libSensors.a file ( path : .pio\libdeps\OpenIMU300ZI\OpenIMU300-base-library\Sensors ), it seems all sensors reading functions are included in this file, but its a library file and source code is not available, can you please provide source code?
Best regards,
Amin.
Dear Li,
I have two questions about magnetometer calibration on openIMU300ZA, when I send 55 55 6D 61 01 02 D1 6C to start mag-align, may I need to read any response on user usart port? ( user usart port pins are 3,4 ) it will be any response on the user usart port? or all responses will be on debug port? I am using AHRS program, which pins are related to debug port? (TX and RX pins)
Best regards,
Amin.
Hi,
please check your GPS baud rate, in source code and in u-center.
Dear Dong,
may I control GPS data input to your INS algorithm by changing gAlgorithm.Behavior.bit.useGPS in source code? I need to toggle between using GPS data input to the INS algorithm and not using GPS data input, when GPS data input in not using by INS algorithm must estimate position without any input data from GPS.
is it possible to control GPS input by changing gAlgorithm.Behavior.bit.useGPS?
Dear Cek,
could you please send me the factory calibration bin file for openIMU300ZA with 1908400114 serial number?
Best regards,
Amin.
Dear Dong,
thanks for your reply, I need more guidance to be able to change your source code, at least please tell me how can I send altitude to the module as commands and what is the maximum possible receive rate by the module and what is the frequency ( sampling rate ) of altitude input in your algorithm? and the GPS update rate?
Best regards,
Amin.
Hi,
Is it possible to use barometric Altitude instead of gps Altitude as input to your INS algorithm? May I send Altitude in meters to openIMU300za from a pressure sensor to improve accuracy of position estimation of your INS algorithm?
Best regards,
Amin.
