Hello! Does anybody know of a way I can connect the PN532 (RFID/NFC module) to the Arduino Nano 33 Sense in SPI mode? I have all of my prior research and everything surrounding it ready, but I'm stumped on how to get this thing working. Here's a diagram of wiring setup to the Uno, in SPI mode. [i…

These forum posts fill in some of the blanks in getting this working, but not enough for me to get my project working: PN532 for Nano 33 BLE Post for initial attempt at using Nano's internal NFC capability

Some further background: I am using an Arduino Nano 33 Sense (REV2) as a pedometer and sending information to a mobile phone app via the PN532. The data transfer only needs to be half duplex since it's only ever needed to send to the phone - that is why I wanted to use i2c, but it looks like SPI is…

I've been able to establish with help from another hobbyist that I should use 3.3v on the Nano for the PN532 module. Now I need to understand the hardware setup required for card emulation using the Nano and PN532. [image]

This thread (here: Library PN532 for nano 33 ble ) looks like it has a solution, but I cannot understand the reason for the change in numbers under Adafruit_SPIDevice fixing the issue. I did a little prying and found that the "1000000" under the Adafruit_SPIDevice library is BusIOBitOrder; the amoun…

Maybe: How can I connect Arduino nano 33 IOT and PN532 module? - Stack Overflow

I tried to follow this to the letter and it hasn't been detecting the PN532 at all while using the emulate_tag_ndef.ino example from Seeed Studio's library (built from Adafruit's). Do you have any other suggestions? I find it strange that it compiles but doesn't detect the module. Lots of 'unused v…
