A sample library to get the MPR121-based touch board from SparkFun up and running. This code is based on the sample Arduino code from SparkFun but is ported to C++ for mbed. The Mbed will require 4.7K pull-up resistors on the i2c SCL and SDA lines to communicate with the board. The IRQ line does not. The example code has the SDA on P28, SCL on P27 and IRQ on P26

Dependencies:   mbed
