Daniel Levine / Adafruit_IS31FL3731

Port of the Adafruit_IS31FL3731 library for Arduino. Enables control of the feather Charliewing LED Matrix peripheral board. Makes use of the I2Cdev library for I2C.

Dependencies:   I2Cdev_MAX32630FTHR

Defaulty uses pinmap for the Maxim 32630FTHR Pegasus board. For a different board, change pin definitions in I2Cdev.h
