Hello,
It could be interesting to add a getGyrOffsets() and a getAccOffsets() methods because I think there is no necessity to compute new offsets every time we power it up.
So, we could save the data computed once and set it in the chip on subsequent power up.

Hi

Would you know if this chip can calculate compass angle like most magnetometer and would you have any example code to calculate rotation count? Example if i rotate the gyro on a table? (Example: 2 counter clockwise ration)

Thanks

Hi,

I am using ICM20948 with ICM20948_WE library and now i am able to get appropriate coordinators of Accelerometer, Gyroscope and Magnetometer one Level of calibration is okay and it's working.

Now i have tried roll,Pitch and Yaw example to find Drift Angle for my skateboard but i am not able to found.

So my issue with Drift Angle can you please give some idea of formula to drive Drift Angle using this all parameter.

I have try with the Vector Formation to drive Angle but i not able to drive this i juse able to drive only heading angle so,

Please suggest me some formula or tutorial for this.

Thanks

Hi,

in examples\ICM20948_08_cycle\ICM20948_08_cycle.ino you wrote that you get wrong data if DLPF is applied. That is mostly intended because you NEED to set the acc DLPF to 7, if you want to use the DLPF, every other setting is out of specs. Take a look at ACCEL_DLPFCFG, Tabel 19, Page 65.
And the sample rate divider is intended to work with a "disabled" DLPF (aka 1X AVG) as you can see in the tabel and also not strange. :D

Hi,
I am using ICM20948_07_pitch_and_roll and using that I am getting two rotational values/degrees change.
But When I do rotation on Surface then I do not see any change. How can we calculate Yaw in Example#7 and have rotation changes in all directions?
