  • Adafruit-PN532

    Arduino library for SPI and I2C access to the PN532 RFID/Near Field Communication chip

    • Hello, for the past 3 days I have been trying to hook up an 20x4 character screen(with an i2c module) and a PN532 module, both trough i2c on an esp32. I've been running in too many problems, sometimes it works, sometimes the esp32 can't keep up(I also need to mention I want to have the screen and the rfid module on different cores of the esp so I can refresh the screen faster). After many failed attempts, noticed how in the Adafruit-PN532 they said how i2c works, but without sharing the i2c bus. My question is. how can I hook up both modules trough i2c(I want to have them both trough i2c so I can save pins since I want to add multiple stuff to it later on).
