Similar to the wire library but more flexible. You may wonder why we cannot use the standard Arduino Wire library, it is because the MMA8453Q uses a repeated start condition for the read operations and the default Wire library cannot handle those without modification.

We use the MS Timer2 library to run the Heart Matrix display function as an interrupt function so that the LED matrices get updated quicker than your eye can make out the individual columns of light. The library is the excellent work of Wim Leers, and we host it here for your downloading convenience :).

The Adafruit GFX library. This is the wonderful work of adafruit we just host it here for convenience. We made the most minor modification of replacing the dash in the library folder with an underscore so this baby is ready for your Arduino library folder out of the box :) Check out the GitHub page for the latest.

Download the latest version of the library! Thanks Github.

Download the latest version of the library! Thanks Github.

A clean and simple library for interfacing with the MMA8453Q chip built on top of Kerry Wong's post and ninjablocks work. We had to change the address to:

const byte I2C_ADDR = 0x1C; //SA0=0

previously it had been 0x1D. Download the MMA8453Q Accelerometer library from Github!
