try with SEROUT2 and use the STR modifier.

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

'Configuring the 16F88 chip

DEFINE OSC 8			'Internal Oscillator set to 8mhz

Pause 2000

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?
