The PN532 module can read and write to RFID tags and cards, making it a versatile tool for applications such as access control systems, inventory management, and .

I am trying to use a PN532 (NFC controller). Lately something in my SPI-communication is off. I start comunication by asking for the firmewareversion (D4 02). Next I .
card or tag and retrieve some basic information about it that can be used to determine what type of card it is. To enable debug message, define DEBUG in pn532/pn532_debug.h The setup works fine and I can read the UID of ISO 14443-3A Mifare Classic 1k cards and tags correctly. But it does not react at all when approached with a Fudan FM1280 .
I try to use 2 PN532 NFC/RFID Readers at the same time. The problem is if I use both of them the program fails or can't find any devices. I tried I2C and SPI but nothing works.
