Motion Tracking Device ICM20948

The ICM20948 is a motion tracking device with a 3-axis

• accelerometer
• gyroscope
• compass

The functionality is similar to the MPU9250 device however with a different programming interface.

To gain some insight how the ICM20948 could be used with the Raspberry Pi I did some basic tests described in this document:

The document describes

• how to connect the ICM20948 via I2C to the Raspberry Pi
• how to do basic test / reading data from the chip with I2C tools of operating system on the Raspberry Pi
• how to access the device with Python

A mini-project is available on GitHub. A Python program retrieves data of accelerometer, gyroscope and compass. A Jupyter notebook does some postprocessing on these data to show some properties of the accelerometer and the gyroscope. The Jupyter notebook and (for better readability) a PDF document are available:
