Cannot create PN532_SPI instance.

[aloyen07]

Hello!
I'm have this code:

#define NFC_INTERFACE_SPI

#include <SPI.h>
#include <PN532_SPI.h>
#include "PN532.h"

PN532_SPI pn532spi(SPI, 6);
PN532 nfc(pn532spi);

void setup() {
  nfc.begin();
}

void loop() {

}

But it not works. Compilator throws this error:

/tmp/ccq7arst.ltrans0.ltrans.o: In function `global constructors keyed to 65535_0_eee.ino.cpp.o.2087':
<artificial>:(.text.startup+0x62): undefined reference to `PN532_SPI::PN532_SPI(SPIClass&, unsigned char)'
collect2: error: ld returned 1 exit status

exit status 1

Compilation error: exit status 1

How to fix it?

Hello, I have happened to solve this issue a while ago. It was happening because newer arduino rules deprecated a syntax declaration used in SPI include file of that library, if memory serves me well. Sorry for now I am not able to post my solution, only this hint to go toward solution. I rember though that the solution was changing few lines of code regarding that deprecated syntax

Same issue here with SPI/HSU or whatever, the linker fail on the sample file although the object files are included.
Same issue with ESP32 or AVR.

Adding -DNFC_INTERFACE_I2C / -DNFC_INTERFACE_SPI to compiler.cpreprocessor.flags.esp32s3= in platform.txt fix the issue (Yes i have "#define NFC_INTERFACE_I2C" at start of my code).

[BenEspinoza10]

@reganissu Im having the exactly same problem, have you remembered the solution?

@reganissu Im having the exactly same problem, have you remembered the solution?

Ok, I have found the workaround I have done and that made everything work for me. I am not totally sure it is on topic for your issue, but I am posting the solution below and you can judge for yourself.

In the PN532_SPI folder, in PN532_SPI.cpp file, in the void PN532_SPI::begin() function in the first 30 lines of code, you have to make the following mod, since SetDataMode and SetBitOrder have been deprecated a long ago (by arduino SPI library I think - not sure):
` _spi->begin();
_spi->beginTransaction(SPISettings(2000000, LSBFIRST, SPI_MODE0));
// _spi->setDataMode(SPI_MODE0); // PN532 only supports mode0 // MOD SPISettings
//_spi->setBitOrder(LSBFIRST); //

// SPISettings(2000000, LSBFIRST, SPI_MODE0);
`
as you can see I have commented out the deprecated declaration, using the "new" accepted SPIsettings declaration.
Hope this helps

[sduponch]

The issue is that #define NFC_INTERFACE_SPI is not set when the compiler build the PN532 lib.

The #define in the ".ino" file seems out of scope : A workaround is to manually edit the compiler args by adding -DNFC_INTERFACE_SPI in the compiler command line (ex: by editing the "platform.txt" in the Arduino "hardware" directory).

[Cincinnatu]

Hello，I just tested this issue and found that adding #include <PN532_SPI.cpp> allows it to run normally.
