Abstract:

This paper presents a real-time data recording system for MSG7000D gyroscope pointing at a feature of digital output interface for domestic MEMS gyroscopes MSG7000D. The main control system is based on FPGA chip and system control module exchanges information with the gyroscope via SPI serial communication interface and thus enabling output data of the gyroscope to record and storage.The paper makes a test and verification to system design by triaxial position swing speed turntable for temperature control. The test result shows that this design of real-time data recording system for MEMS gyroscope MSG7000D is effective and practical and lays a foundation for the subsequent engineering applications gyroscope and has a certain value in engineering.
