RFID Module
3.3 EXAMPLE APPLICATION
Aer you have successfully installed the library, your module is ready for use.
You can use the following code example and transfer it to your Arduino to start up and test the module.
#include <SPI.h>
#include <MFRC522.h>
#define RST_PIN 9
#define SS_PIN 10
MFRC522 mfrc522(SS_PIN, RST_PIN);
void setup() {
//Initialisierung des RFID-Moduls
Serial.begin(9600);
while (!Serial);
SPI.begin();
mfrc522.PCD_Init();
mfrc522.PCD_DumpVersionToSerial(); //Details des Lesegerätes ausge-
ben
Serial.println(F("Scan PICC to see UID, type, and data blocks..."));
}
void loop() {
//Suche nach neuen Karten
if ( ! mfrc522.PICC_IsNewCardPresent()) {
return;
}
if ( ! mfrc522.PICC_ReadCardSerial()) {
return;
}
//Informationsabruf des RFID-Gerätes
mfrc522.PICC_DumpToSerial(&(mfrc522.uid));
}
