i was purchase RFID Module from http://www.stronglink.cn/english/sl015m1.htm
but them has only AVR Example code I don't understand it about AVR programing
am tried to create arduino code but not work any body please help me convert avr code to arduino
or arduino code to read Tag id for this Module
:) :) :)
this is arduino code ( not work )
#include <NewSoftSerial.h>
/*
This program tests communication with the Seeeduino 13.56 RFID Reader by sending a request for the unit's serial number and getting a response.
We need 4 pins connected from the RFID to the Arduino : These all come from connector J2
RFID -> ARDUINO
TX -> TX (pin 4)
RX -> RX (pin 3)
+5V -> +5V
GND -> GND
NOTES :
1.Debug info and received data will be sent through the Arduino to your serial monitor. You should have it open to see anything!
You should see something like this :
The RFID test program has started
Header = AA
Station ID = 00
Data Length = 1
Command = 83
Checksum = 82
Footer = BB
Listening for response...
I received: AA
I received: 0
I received: A
I received: 0
I received: 0
I received: FF
I received: FF
I received: FF
I received: FF
I received: FF
I received: FF
I received: FF
I received: FF
I received: A
I received: BB
NOTES (Continued)
2.The reset pin on the RFID should be tied to GND, either on the RFID or the Arduino
3.Please note that this test program outputs debug data with no trailing zero : so for example '00' becomes '0' and '0A' becomes 'A'
4.If you're not seeing any response from the RFID unit, chances are that you have your RX and TX pins round the wrong way.
5.This code uses the 'NewSoftSerial' library to set up another serial port on pins 3+4 of your Arduino. You must download the library and 'include' it in your code (using Sketch:Import Library from the Menu bar). Library can be found at : arduiniana.org/libraries/newsoftserial/
6.The code used to send the data section of the packet has not been properly tested.
