My question is similar to this one but I have a question I would like to ask and I can't comment below, so I would like to extend the question here.
I have a Raspberry Pico with micropython installed and I have a PN532 to read NFC tags via i2c. I have tried various libraries as well as Adafruit's Lib which is based on CircuitPython. I chose to stay on micropython for other reasons so this was not an option. To go further on my quest I followed the link to the YouTube video: youtube.com/watch?v=NuVhXdyeZvQ&t=1171s and the Link to the GitHub repo: github.com/somervda/nfc-tester/tree/… . Now this reads the tags successfully. However the interrupts don't seem to work as they should. There is a keypad present and some irq's set that don't react to pressing, unless the block of code for rfid reads a card.
Is this how the library is supposed to work? Is it polling based or interrupt driven? Why the interrupts don't activate?
