madgwick filter #419

Hi I have a question about how to filter mpu9250 data. I read the raw data of the sensor, but I had trouble getting Quaternion. The output q is unstable at all, and the data of the roll, pitch, and yaw I obtained are constantly increasing. Most likely they are wrong. How can I solve this problem? If you can help, thanks

You need an STM32 development board and an MPU9250 breakout board. I recommend this https://www.tindie.com/products/tleracorp/ladybug-stm32l432-development-board/ and this https://www.tindie.com/products/tleracorp/mpu9250-add-ons-for-ladybug/.

The MPU9250 breakout mounts directly on top or bottom of the Ladybug; this is all you need for reasonably accurate AHRS.

I mean, other than Mcu stm32, do I need another board or device for get output and calibration sensor?
