Arduino Due + PN532 elechouse

i received pn532 elechouse , wanted test it.

first follow pdf: https://dangerousthings.com/wp-content/uploads/pn532_manual_v3-1.pdf


hardware
pn532: put switch this: i2c   1  /  0  (p3)
i plug show on page 5 :
5v
gnd
pin 20 /sda
pin 21/scl

software
as show on page 5 download this:
pn532
pn532_hsu
pn532_i2c
pn532_spi
from here: https://github.com/elechouse/pn532
ans ndef

then choose example : iso14443a_uid
and change this

quote

#if 0
  #include <spi.h>
  #include <pn532_spi.h>
  #include "pn532.h"

  pn532_spi pn532spi(spi, 10);
  pn532 nfc(pn532spi);
#elif 1
  #include <pn532_hsu.h>
  #include <pn532.h>
      
  pn532_hsu pn532hsu(serial1);
  pn532 nfc(pn532hsu);
#else
  #include <wire.h>
  #include <pn532_i2c.h>
  #include <pn532.h>
  #include <nfcadapter.h>
  
  pn532_i2c pn532i2c(wire);
  pn532 nfc(pn532i2c);
#endif

to this:

quote

#if 0
  #include <spi.h>
  #include <pn532_spi.h>
  #include "pn532.h"

  pn532_spi pn532spi(spi, 10);
  pn532 nfc(pn532spi);
#elif 0
  #include <pn532_hsu.h>
  #include <pn532.h>
      
  pn532_hsu pn532hsu(serial1);
  pn532 nfc(pn532hsu);
#else
  #include <wire.h>
  #include <pn532_i2c.h>
  #include <pn532.h>
  #include <nfcadapter.h>
  
  pn532_i2c pn532i2c(wire);
  pn532 nfc(pn532i2c);
#endif

in order test i2c have this:
hello!
didn't find pn53x board


original code:

/**************************************************************************/

**ps:
i manage detect following code arduino nano friend share me : http://arduino.ru/forum/proekty/chitaem-nomera-rfid-nfc-kart-metok-s-pomoshchyu-modulya-s-chipom-pn532-1356-mhz
but can detect pn532 lib, want test read/write , it's not nano.

if select hsu instead of i2c have lot of error :
