Detailed Description

Internal definitions for TDK/Chirp ICU ultrasonic sensors.

This file contains various hardware-defined values for ICU series sensors, including ICU-20201.

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.
