fsl_fxas21002_i2cspi_3D_gyro.c File Reference

The FXAS21002 is a 3-axis Angular Rate Gyroscope from Freescale that supports both I2C and SPI protocols. This source file implements the interface for the FXAS21002 Sensor Adapter. It uses Device Messaging (DM), which abstracts away the differences between the I2C and SPI protocols, to communicate with the device. This choice is made via the system communication file, isf_sysconf_comms.c. This file also uses the Bus Manager (BM) to schedule a periodic callback for reading new sensor data and sending the data to the Sensor Manager (SM). More...
