Arduino communication library for the RDM6300 RFID reader

RDM6300

Arduino library for the RDM6300 125kHZ RFID reader

Example:

#include <Arduino.h>
#include <SerialPrintF.h>
#include "RDM6300.h"

#define SERIAL_BAUD_RATE 9600
#define RDM6300_TX_PIN 10
#define RDM6300_RX_PIN 11

RDM6300 rdm6300(RDM6300_TX_PIN, RDM6300_RX_PIN);

void setup() {
    Serial.begin(SERIAL_BAUD_RATE);
}

void loop() {

    RFIDTag rfidTag = rdm6300.readTag();

    serial_printf(Serial, "Version: %l, Id: %l, Checksum: %s, Read Timed Out: %s\n",
                  rfidTag.version,
                  rfidTag.id,
                  rfidTag.isChecksumValid ? "true": "false",
                  rfidTag.isReadTimedOut ? "true": "false");
}

You need the following files:

• src/RDM6300.h & src/RDM6300.cpp
• src/GenericUtils.h & src/GenericUtils.cpp
• src/SerialUtils.h

Initialization:

RDM6300 rdm6300(txPin, rxPin) which will return you a class with operation onto the reader

readTag() which will block until a tag is read

readTag(readTimeoutMS) which will block until the given milliseconds and if tag is not read, then the isReadTimedOut field will be true

Features:

• Timeouts
• Documentation

Communication Notes:

Here is a little example that I drawn to express how to handle the data. That doesn't concerns the end user.
