Hi,I'm testing the MotionFX library with the Discovery Kit IoT node [B-L4S5I-IOT01-A] and I have a problem: randomly the sensor fusion algorithm "explodes" and I can only get only "nan" values for all the `MFX_MagCal_output_t` values, Gyro Biases inc...

Posted on June 26, 2014 at 16:31 Hi, I tried to configure my STm32F207 using the ''Cube'' to use the CAN2 and I found a bug. This is the initialization code generated by the ''Cube'': void HAL_CAN_MspInit(CAN_HandleTypeDef* ...

Posted on April 24, 2014 at 14:18 Hi, I would like to signal a bug using STm32Cube to configurate timers in InputCapture mode to measure the duration of an input signal resting at low level. Using the method described in AN4013 at page...

@Miroslav BATEK Thank you for your support. I finally found the issue. The "nan" problem was generated by the "timestamp overflow". In the IMU Task, I have a code that handles the overflow and recast the timestamp on a `uint64_t` variable, but there...

Thank you for checking the code.I have a log application that I can use to save the data. I only need to modify it to retrieve also the mag raw and biases.I will share the data as soon as they are ready

@Miroslav BATEK I shared the code of IMU, Magnetometer, and MotionFX tasks on Dropbox.Let me know if you can correctly get it.

So I'm using correct data units. At this point, the only problem can come from accelerometer or magnetometer calibration.Is there a way to provide an initial guess of magnetometer biases to the algorithm?
