Detailed Description

Internal definitions for the Chirp CH101 GPPC sensor firmware.

This file contains register offsets and other values for use with the CH101 GPPC sensor firmware. These values are subject to change without notice.

You should not need to edit this file or call the driver functions directly. Doing so will reduce your ability to benefit from future enhancements and releases from Chirp.
