A simple library to interface with RDM6300 RFID reader.
- Fast and single tag reading, even if it held near the antenna for a while.
- Using a single given GPIO pin or a
Stream. - Can tell if the tag is still near the antenna.
- Both hardware and software uart (serial) support on esp8266.
- SAMD hardware uart (serial) support.
- Both SoftwareSerial and AltSoftSerial support.
- RDM6300 module with matching antenna.
- 125KHz RFID tags.
- Microcontroller (arduino, esp8266, esp32...).
A simple RFID tag reader with textual serial output:
examples/read_to_serial/read_to_serial.ino
void begin(Stream *stream)- Initialize instance to read from a given stream.void begin(int rx_pin, uint8_t uart_nr=1)- Initialize instance to read from a given pin.void set_tag_timeout(uint32_t tag_timeout_ms)- sets the tag "valid" timeout, (300ms default)
RDM6300 sends packet every 65ms when tag is near- better higher values for debouncing.uint32_t get_tag_id()- Returns the tag_id as long as it is near, 0 otherwise.uint32_t get_new_tag_id()- Returns the tag_id of a "new" near tag,
following calls will return 0 as long as the same tag is kept near.bool update()- Updates the internal values must be called repeatedly!bool is_tag_near()- Returns whether a tag is held near.get_tag_id().
