Using the Xtrinsic FXOS8700CQ
Command Line Interface
Software

1 Introduction
The FXOS8700CQ command line interface driver
provides an easy way to communicate with the
FXOS8700CQ using the RD4247FXOS8700 sensor
toolbox platform. Once the sensor toolbox board is
programmed with this firmware, the user can
• modify and read registers,
• view details of the operating mode of the device,
• and stream/view data as signed counts or in
signed units
using a generic terminal program via a virtual serial port
over USB.
