Which function is it that goes to the error handler? It's difficult to tell in the picture.

Hi Jared,

I have a nRF52840 DK and PN532 NFC Reader.

i have followed the steps mentioned in this tutorial.

https://devzone.nordicsemi.com/b/blog/posts/how-to-test-nrf52-nfc-tag-with-reader-adafruit-tag

when debugging the kit via segger embedded studio im getting some error after adafruit_pn532_init();

im flashing the example code given in SDK nRF5_SDK_15.2.0_9412b96\examples\nfc\adafruit_tag_reader\pca10040

PIN 35 and PIN 36 is P1.3 and P1.4 respectively.

Hi Jared,

Cannot find PINs 35 and 36 on nRF52840 DK.

Can you show the PIN numbers marked on the pinout diagram of nRF52840 DK?

Thanks!

A reader is necessary, the nRF52840 should work with the Adafruit PN532 NFC reader by replacing the pin configurations for irq and reset in the config file so that it fits the nRF52840.

Current SDK file:

// <o> PN532_IRQ

#ifndef PN532_IRQ

#define PN532_IRQ 13

#endif

// <o> PN532_RESET

#ifndef PN532_RESET

#define PN532_RESET 14

#endif

After changes:

// <o> PN532_IRQ

#ifndef PN532_IRQ

#define PN532_IRQ 35

#endif

// <o> PN532_RESET

#ifndef PN532_RESET

#define PN532_RESET 36

#endif
