Design of Attitude Sensor Acquisition System Based on STM32

The main controller STM32 is applied to the attitude sensor data acquisition system, which made reduce costs and development cycles. Firstly, according to the design requirement, the frame of the attitude sensor acquisition system is described. Secondly, the hardware circuit gives a design. The key circuits are described, and include MPU6050 circuit and STM32 interface circuit. Then, Using keil software to design the STM32 driver program, using Lab Windows/CVI virtual platform to write the host computer program. Finally, the MPU6050 sensor is tested and analyzed in the Lab Windows/CVI virtual platform, Through many experiments, it is found that the Kalman filter is more effective to reduce the error of the sensor.
