NFC ans Samsung

[feelgoodgirl]

Hey,
In your description, I saw that this library should good for my project. My goal is to read and send messages with a smartphone with NFC. I tryed the P2P_Send example.

When I introduced your library and chanch the follinging in the code:

#include <Wire.h>
#include <PN532_I2C.h>
#include <PN532.h>
#include <NfcAdapter.h>

PN532_I2C pn532_i2c(Wire);
NfcAdapter nfc = NfcAdapter(pn532_i2c);

i got the measege that #include <PN532.h> where not include.
After I added this library, I received the following message:

Arduino: 1.8.2 (Windows 7), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

option enabled in File -> Preferences.

Could you possibly help me?

I have the same problem

It sounds like PN532 libraries might not be installed correctly. This library is a pain to install because of the multiple libraries and lack of Arduino IDE integration.

Here's how I install it on my Mac

cd ~/Documents/Arduino/libraries
git clone https://github.com/don/NDEF.git
git clone https://github.com/Seeed-Studio/PN532 NFC
ln -s NFC/PN532 .
ln -s NFC/PN532_SPI .
ln -s NFC/PN532_I2C .
ln -s NFC/PN532_HSU .

[don]

On Windows it's similar but I copy the directories rather than creating symbolic links

Open a cmd prompt

cd Documents\Arduino\libraries
git clone https://github.com/don/NDEF.git
git clone https://github.com/Seeed-Studio/PN532 NFC
move NFC\PN532 .
move NFC\PN532_HSU .
move NFC\PN532_I2C .
move NFC\PN532_SPI .
rd /s /q NFC

Hopefully that helps. This issue is old so I'm closing it. Open a new issue if you're still having a problem.
