Fix example for gamepad

deshipu · deshipu · commit 0ff128ec0309 · 2018-01-11T17:06:53.000+01:00
The example code for the gamepad module would skip detected
button presses in the code that waits for a button to be released,
because it would run it even when no button is pressed.

Also updated the example pin names to not use RX and TX.
