Do I need to poll all the time to check whether a key has been pressed ? I'm using SIOReadKeypad, I set up a thread which just continually calls SIOReadKeypad.

Any help is much appreciated.

If you set the keypad timeout to -1
    SetKeypadTimeout(-1);
then SIOReadKeypad() will wait for a keypress.

Ok, but do I still need to keep polling the SIOReadKeypad function within a loop to continually get the key pressed ? Could I not set up a notification ?
Under the hood, is the SIOReadKeypad() using interrupts ?

Thanks,
Steve

Yes, you can set up a notification. See topic 2052 for a sample application.
