I am looking for library for PN532 RFID/NFC Card Reader (red board) via I2C on CORE-ESP32-C3
I found only support for Arduino IDE but not for ESP-IDF.
I only found this old library, but without an example to use and documentation.
https://github.com/lucafaccin/esp-pn532
I also get error with ESP32-C3 and clock and i2c_set_timeout, that I solved but I am not sure the correct value for the clock
In any way the code word, but not recognize the board , it not read the Firmware version of the board.
The boards are this:

Hello,
What about this one? https://github.com/thanhbinh89/pn532-esp-idf

Re: Looking for library for PN532 RFID/NFC Card Reader
this library use SPI with 4 wire, I would use I2C with only 2 wire, Because I have already almost all pins of Core-Esp32-c3 used. I am doing a door access system, and I use RFid card and matrix keyboard, this one use 7 gpio pins.

Hey Did you ever manage to get it to work with i2c it seems i can get everything going except for reading tags wondering if you could shed any light thanks
