How to compare strings/array? RFID Project

[CSU_2010]

Thanks, I tried SERIN2 and SEROUT 2, the LCD is still displaying weird symbols. It displays eveything else ok. Here's the code:

SEROUT2 lcd,396,[$FE,$C0,STR buf\10]

Pause 5000

Goto loop

End					'End of main program

Try something, start a new code, fill the buf Array with some data (ASCII character), then send it to your LCD.

Any link for your RFID reader?

Maybe not a bad idea to connect the RFID to your PC to see what happen... you'll need a MAX232 or any other level converter to do that.

Just curious to know if the following line work with your LCD

SEROUT2 lcd,396,[$FE,$C0,"2nd Line???"]

Thanks for the replies, I'll try it out in lab tomorrow. Here's a link to the RFID Parallax RFID
I'll have to look up the stuff on attaching it to a computer, I've never done anything like that.

I'm trying to find out the RFID tag ID by reading the tag and displaying it on an LCD and I can't seem to figure it out. Has anyone else been able to display the tag ID on an LCD?

I was at Radio Shack yesterday, trying to buy a breadboard. (No of course they didn't have it, why would my store have it in stock?)

Anyway, I was searching their bins and I saw a Parallax RFID READER WITH TAGS part number 276-0032, or this part: http://www.parallax.com/Store/Sensor...%2cProductName

It didn't have a price marked, so I had the lady scan it, and she told me it was $19.97. It's on my receipt as the correct part number, and correct product description. That's half off of Parallax's price, so if you are interested in RFID, you might want to check it out at Radio Shack.
