    • RE: Elechouse PN532 NFC Module V3 for Arduino etc.

      I, too, stops on the line nfc.begin(); if disconnect board or select another pin - Didn't find PN53x board. Connect to I2C. SPI don`t work too.

      hardware\arduino\avr\libraries\Wire\utility\twi.c

      uint8_t **twi_writeTo**(uint8_t address, uint8_t* data, uint8_t length, uint8_t wait, uint8_t sendStop)
      {
       . . . . . . . . . . . . . . . . . . . 
        // wait for write operation to complete
        while(wait && (TWI_MTX == twi_state)){
          continue; //**stops here**
        }
        
        if (twi_error == 0xFF)
          return 0;	// success
        else if (twi_error == TW_MT_SLA_NACK)
          return 2;	// error: address send, nack received
        else if (twi_error == TW_MT_DATA_NACK)
          return 3;	// error: data send, nack received
        else
          return 4;	// other twi error
      }
