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.

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-C...
