[QUOTE="alexburcea, post: 517, member: 3"] Normally there is no problem to poll at 10 or even 100Hz... The feature you so there is apply to a different card but your card is made with an IOExpander chip and has this functionality by default enabled. You can poll or set an interrupt for GPIO11 (connector pin 23) to see if any input has changed. Make sure you enable the Raspberry pin pull-up resistor because the chip output is open-collector.
