摘要:

利用OMAP3530为硬件平台,在Linux操作系统下,采用I2C总线协议方式,实现对L3G4200D三轴陀螺仪的驱动。以L3G4200D传感I2C接口具有的快速模式,配合OMAP3530硬件的外界I2C接口,实现了对L3G4200D三轴数字陀螺仪实时的高数数据采集。

关键词: I2C总线, L3G4200D陀螺仪, 设备驱动

Abstract:

This paper uses I2C bus protocol to design L3G4200D three-axis gyroscope driver on the Linux operating system with OMAP3530 as the hardware platform.Real-time digital high number of data collection of the L3G4200D three-axis gyroscope is realized using the fast mode of L3G4200D sensing I2C interface and the OMAP3530 hardware output I2C interface.

Key words: I2C bus;L3G4200D;device drivers
