RFID Tag Ouput

Hi guys,

I have here the Basic Stamp homework Board with a RFID reader from Parallax Company. My plan is the following:

The reader should recognize the serial of the tag. I know, how the reader reads the tag. Now I want to make, that the reader sends this tag at the computer. But how? Is it possible to write down the tag (different tags) in a textfile? Does anybody have a solution?

Greetings, Tobias

    1) You can use the DEBUG statement to transmit the RFID number to your PC. You will need a program on the PC to receive the information and write it to a text file. For testing purposes, you can just use the debug window of the Stamp Editor, but that will only display the information received. A program like StampPlot has logging ability (www.selmaware.com).

    2) You can buy an additional piece of hardware that can attach to the homework board and write information to a text file on a memory card or memory stick. The Parallax Datalogger (www.parallax.com/detail.asp?product_id=27937) is one such device.

    Hi, thanks for the quick answer.

    1) I read something about the DEBUG statement. I think, it should work with the StampPlot. I think, that will be my last option to do it in this way.

    2) This idea is very good. The only problem is, that I cannot connect this Datalogger on my board, because most of the needed space is used by the RFID reader.

    Hey,

    I though about it and I came to the decison, that it should be possible to change the pins of the RFID reader.

    Another option is the datalogger from Hitt Consulting (www.hittconsulting.com/). This is more limited. It allows reading and appending to files, not general access. Also, it's limited in the size of the memory card that you can use and the number of files you can have. Its advantage is that it's very small and uses very little power. For your purpose, it may be more than adequate.

    Thank you, but I think, I will try it with the Parallax DataLogger. Know I have to find a possiblility to order it from Norway.

    Should it be PLX-DAQ rather than Stamplot as this is more·for creating·graphs whereas PLX-DAQ·logs·data to Excel?

    Hey,

    I though about it and I came to the decison, that it should be possible to change the pins of the RFID reader    . NOT A GOOD idea.gif

    This is not a good idea because i have try this and fried a RFID Card Reader Board doing it the best thing to do is take a solder bread board and cut it to the size to fit the 5 volt reg and the pins on the RFID Card Reader this works alot beter than trying to pull the pins off the RFID Card Reader Board trust me on this one
