Design of an MPU9250-Based Attitude Data Measurement System

Attitude solving plays a crucial role in various fields, as it enables accurate determination of an object's orientation and helps optimize system performance. By providing precise attitude information, the MPU9250 nine-axis sensor contributes to the design of balance bikes, aerial mice, and other applications. The project utilizes the STM32F767 microcontroller to interface with the MPU9250 sensor, enabling the acquisition of raw data. The Digital Motion Processor (DMP) and Motion Process Library (MPL) library are employed to perform attitude solving, allowing for real-time estimation of the object's Euler angles. The results from the proposed method demonstrate accuracy, providing a reliable and cost-effective solution for precise attitude resolution. This research enhances operational efficiency, optimizes system performance, and reduces computational complexity. Future efforts will focus on mitigating errors arising from environmental factors.
