adafruit_circuitplayground's Introduction

Adafruit Circuit Playground Library

Library to program Circuit Playground Classic and Circuit Playground Express in C++ with the Arduino IDE.

Installation

On the Arduino IDE (v. 1.8.5+) use the Library Manager in order to install this library. Documentation can be found on the Adafruit's learning

Usage

This Readme is not as exhaustive as the example code or the official documentation that can be found here (CPX) and here (CPC). It is intended to be a reference where to find the listing of the library's functions at a glance.
