bonjour
je débute sous arduino et je voudrais trouver la "primary expression" qui définie un tag en particulier pour lui assigner une fonction lors de sa lecture je vous remercie d'avance, voici le code du programme:
//This example reads all MIFARE memory block from 0x00 to 0x63.
//It is tested with a new MIFARE 1K cards. Uses default keys for authenication.
//Contributed by Seeed Technology Inc (www.seeedstudio.com)
#include <PN532.h>
#include <SPI.h>
/Chip select pin can be connected to D10 or D9 which is hareware optional/
/if you the version of NFC Shield from SeeedStudio is v2.0./
#define PN532_CS 10
PN532 nfc(PN532_CS);
#define NFC_DEMO_DEBUG 1
void setup(void) {
#ifdef NFC_DEMO_DEBUG
Serial.begin(9600);
Serial.println("Hello!");
#endif
nfc.begin();
uint32_t versiondata = nfc.getFirmwareVersion();
if (! versiondata) {
#ifdef NFC_DEMO_DEBUG
Serial.print("Didn't find PN53x board");
#endif
while (1); // halt
}
#ifdef NFC_DEMO_DEBUG
// Got ok data, print it out!
Serial.print("Found chip PN5");
Serial.println((versiondata>>24) & 0xFF, HEX);
Serial.print("Firmware ver. ");
Serial.print((versiondata>>16) & 0xFF, DEC);
Serial.print('.');
Serial.println((versiondata>>8) & 0xFF, DEC);
Serial.print("Supports ");
Serial.println(versiondata & 0xFF, HEX);
#endif
// configure board to read RFID tags and cards
nfc.SAMConfig();
}
void loop(void) {
uint32_t id;
// look for MiFare type cards
id = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A);
if (id != 0)
{
#ifdef NFC_DEMO_DEBUG
Serial.print("Read card #");
Serial.println(id);
Serial.println();
#endif
uint8_t keys[]= { 0xFF,0xFF,0xFF,0xFF,0xFF,0xFF };// default key of a fresh card
for(uint8_t blockn=0;blockn<64;blockn++)
{
if(nfc.authenticateBlock(1, id ,blockn,KEY_A,keys)) //authenticate block blockn
{
//if authentication successful
uint8_t block[16];
//read memory block blockn
if(nfc.readMemoryBlock(1,blockn,block))
{
#ifdef NFC_DEMO_DEBUG
//if read operation is successful
for(uint8_t i=0;i<16;i++)
{
//print memory block
Serial.print(block*,HEX);*
