Hi,
I am using the example Code from the wiki plus adding a few lines for visual feedback.
I get the "Scan a NFC tag" message on my serial monitor but it does not detect a Tag.

It worked with my Arduino UNO when I changed Serial1 to Serial, but that does not work with Leonardo. I get an error message
during compilation.

[code] #include “PN532_HSU.h” #include “PN532.h” #include “NfcAdapter.h”
PN532_HSU interface(Serial1); NfcAdapter nfc = NfcAdapter(interface); #define rLED 8 void setup(void) { Serial.begin(115200); nfc.begin(); Serial.println(“NDEF Reader”); pinMode(rLED, OUTPUT); // testing LED functionality digitalWrite(rLED, HIGH); delay(200); digitalWrite(rLED, LOW); delay(200); digitalWrite(rLED, HIGH); delay(200); digitalWrite(rLED, LOW); }
void loop(void) { Serial.println(“\nScan a NFC tag\n”); if (nfc.tagPresent()) { digitalWrite(rLED, HIGH); delay(500); digitalWrite(rLED, LOW); NfcTag tag = nfc.read(); tag.print(); } delay(5000); } [/code]

Hi ~, We see the same issue and we are looking @ the issue and keep you posted. thanks.
