rdm6300

A simple library to interface with RDM6300 RFID reader.

Features

• Fast and single tag reading, even if it held near the antenna for a while.
• Using a single configurable GPIO pin.
• Can tell if the tag is still near the antenna.
• Both hardware and software uart (serial) support on esp8266.
• Both SoftwareSerial and AltSoftSerial support.

Getting Started

Hardware

• RDM6300 module with matching antenna.
• 125KHz RFID tags.
• Microcontroller (arduino, esp8266, esp32...).

Software

A simple RFID to serial reciver example can be found at: examples/read_to_serial/read_to_serial.ino

API

• void begin(Stream \*stream) - Initialize the object to use the given stream to read from the RDM6300.
• void begin(int rxPin, uint8_t uart_nr=1) - Initialize the object to use the given GPIO pin as RX from the RDM6300.
• bool update() - Updates the internal values by reading from the RDM6300, returns true on tag detection, must be called repeatedly!
• uint32_t get_tag_id() - Returns the last tag id read by update- can be called only once after update.
• const char * get_s_tag_id() - Returns the last tag id read by update as a 10-digit hex string - can be called only once after update.
• bool is_tag_near() - Returns whether a tag is currently held near the antenna- can be called many times after update.

Enjoy!
