Using old RFID reader

Other Hardware Sensors
1

Hello

I am trying to recycle an old connected object (nabaztag:tag).

First I am trying to use the old RFID reader.

rfid_reader
rfid_reader1793×1947 194 KB

According to some informations that I found on this module :

  • The module have the ID : Y2006154-GY-B0 but I don't find anything about this.
  • The microchip have the ID CR14P-1GE

With this post on github I identify VCC, GND, SDA, SCL pins. And I have connected them to arduino.

But now wich library can I use to verify that I can read an old RFIF tag with it?

I am very new to electronic and arduino.

Thanks for help.

If it really is an I2C device and is connected and powered correctly then is it recognised by the I2C scanner sketch and if so what is its address ?

Have you tried running the i2c scanner sketch on the Arduino? Hopefully this will confirm that the board is working and what address it has on the bus.

I didn't know about IC2 scanner :slight_smile:

So I tried... And here is the result :

09:49:08.242 -> I2C Scanner
09:49:08.242 -> Scanning...
09:49:08.242 -> I2C device found at address 0x50 !
09:49:08.284 -> done

So address is 0x50.

And now?

Need to find the data sheet for this chip, I suspect!

That means that you can read the raw data using the Wire library but that is not much help if you don't have the data sheet of the chip that you are reading.

It may be worth trying the MRFC522 library which is available in the Library Manager

@UKHeliBob and I are in-sync today!

Link please!

Yes sorry, forgot the link :frowning:

Link : GitHub - rngtng/NabaztagInjector: Arduino library to send data to Nabaztag via I2C (RFID injected)

I have tried to find something with MRFC522.

I found this : MFRC522-spi-i2c-uart-async - Arduino Reference

I installed library and try to compile the example Minimal-I2C.

But I have got an error on TwoWire : TwoWire does not name a type :frowning:

I am very new to Arduino so I don't know what I can do with this error...
