[gaurav]

i am interfacing rfid with arm lpc 2148 and trying to display the tag’s value on the lcd as it is a part of my project and i am not able to do it. garbage value will be displayed when the tag is flashed on the reader.

i would require your help in interfacing ……

Hi,

 

Well when you are interfacing LCD with LPC 2148, take care of logic level shifter means LPC 2148 operates at 3.3V while LCD need 5V for opration.

 

On this site, see ARM section. You will find a solution soon.

Hi,

 

You can do one thing. See what data RFID reader is transmitting on Hyperterminal. If its receiving data properly on Hyperterminal, the issue is with LPC 2148 side. Make sure you have properly configured BAUDRATE of LPC2148. 

 

It will be nice if you can post snapshot of data received on Hyperterminal.

 

All the best.

Hi,

      which interface you are going to use for the RFID tag?(E.g.Uart ,SPI).CMSIS library for the lpc17xx are available on LPCWARE.So you can get most of the driver there.

[vamshi]

sir i want to interface through UART.so sir am not getting any idea..so can u plz post the code.To read the tags…plz sir it is the only module which has remained in my project..plzhelp me
