SparkFun Qwiic Universal Auto-Detect

SparkFun ESP32 Thing Plus C (SPX-18018)

The SparkFun Qwiic Universal Auto-Detect library makes it easy to create a scalable Qwiic (I²C) sensing and logging device on a wide range of platforms.

Key Features

• Automatic detection of a wide range of Qwiic sensors
  • Built-in Qwiic Mux support
• Only one library to install
  • This library contains automatically-updated copies of all the necessary sensor libraries
• Adding new sensors is easy
  • There is only one file to add and three files to modify when adding a new sensor
• Built-in menu system
• The sensor and menu configuration can be stored in:
  • EEPROM
  • LittleFS
  • SD or microSD card: both SD and SdFat are supported

Getting Started

The Getting Started Page outlines library installation and the general use of the SparkFun Qwiic Universal Auto-Detect library.

Detailed examples are included as part of the library installation process and available in the Arduino IDE File > Examples > menu. A walk-thru of key examples is contained in the Examples section of this documentation set.

A full API Reference is also provided for the library.
