SparkFun Authentication Coprocessor Arduino Library

An Arduino library for the Auth 3.0 Coprocessor - precompiled for ESP32

This library supports the Apple Authentication 3.0 Coprocessor (MFI343S00176/77) as defined in the Accessory Interface Specification (Release R44). Unfortunately, the Interface Specification is only available under NDA. This library is precompiled for the ESP32 to protect the source code.

Example01_BasicUsage demonstrates how to communicate with the Coprocessor over I2C.

This library depends on the SparkFun Toolkit (>=1.0.6).
