  **Ignore the title of the plots** These plots are my attempt to account for soft & hard iron biases . Hi Kris, does this magnetometer look calibrated for...

 Looking at this illustration of MPU9250 given that I choose Y-axis to point North and choose to used the NED system. Would my input be madgwickquaternionupdate(ay, ax, az,...

I have just seen that the axis of Mag ang accel & gyro are misaligned on the MPU9250 datasheet.  so let me ask the question again with this new...

Hi Kris, your simple method for calibration is very effective, however I wanted to implement an even more accurate calibration method that are suited for commercial applications of autonomous vehicles....

Hi there Kris, first off your Github page is a gold mine. Secondly, in this code `// Get hard iron correction mag_bias[0] = (mag_max[0] + mag_min[0])/2; // get average x...

Is that the same as the Sensitivity adjust values as shown in this picture? If not how could I calculate/find this value? What value did you use? Many thanks 

Hi Kris, other than accounting for soft-iron and hard-iron biases, is there any other calculation I need to do before inputting mag data into madwickquaternionupdate() function. Correcting for magnetic declination...

I just came across this post where you mention accounting for declination in your response. "you have taken into account the local magnetic declination". https://github.com/kriswiner/MPU9250/issues/345 Just a bit confused now......

Hi all, in this Loss Function do you guys know what the `pad_mask` variable is? I thought the target would have one channel per Class. Whereas this functions suggests a...
