I haven't tried this year yet, but I have been successful in the past (2013 was the last year I think I used it). Could you share your code (screenshot will do) and circuit?
Some things to keep in mind, the DIO ports are pulled high to 3.3V using a 40 kOhm resistor. If you want to trigger something, you have to pull that signal to ground. You'll probably want to use a falling-edge trigger.
