is there a polling-only Linux C code example for the X-NUCLEO-NFC09A1? The demo app is IRQ based and we plan to use many readers so it would be convenient to save the IRQ pin and use only the CS pin per device.
nothing available out of the box. You can try and change st25r200WaitForInterruptsTimed(): Set the experimental ST25R_POLL_IRQ and see if this is already sufficient (was in the past).
