Using the Pmod CDC1 with Arduino Uno

This is a demo project for the Pmod CDC1 made by Digilent. This module is a capacitive-to-digital converter, which senses inputs through two capacitive buttons and outputs them using digital, or I2C interface. To control the Pmod, an Arduino UNO is used. Two interrupts are attached to the digital outputs of the module, to sense rising edges of the signals and display a message if triggered. As the capacitive touch buttons are very sensitive, the interrupts may be triggered multiples times after one touch.
