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

      hello
      I'm having the same problem: arduino one brake on the line nfc.begin();
      I'm new in arduino and nfc, but I've downloaded pn532 libraries, set pin 1-0 on the board, all the 4 wires are ok (vcc, gnd, sda, scl); the serial speed is set to 115200
      in this code:

        #include <Wire.h>
        #include <PN532_I2C.h>
        #include <PN532.h>
        #include <NfcAdapter.h>
        PN532_I2C pn532i2c(Wire);
        PN532 nfc(pn532i2c);
        
      void setup(void) {
        Serial.begin(115200);
        Serial.println("Hello!");
        nfc.begin();
        Serial.println("second Hello!");
      

      the serial write just the first Hello!
      I can't find a solution... Help me!!

      ok
      now it works!
      in SPI mode (jumper 0 - 1) and SCK MISO MOSI SS VCC GND

      thank you all
      Massimo
