I have found a number of examples in the Arduino libraries but I am having trouble finding documentation on how to code in CircuitPython to use the IRQ function of the PN532 board.
I have a project that I would like to send to sleep while it waits for a card rather then contently polling for a card.
I found mention of being able to do it in CircuitPython but how do you code for it? Can someone please point me to some documentation my webfo is clearly not strong enough.
Thank you so much for your time.
