RFID Tag Detection using ARM7

Hello Everybody,

Thanks for visiting the First post of my first blog.

In this post I will be discussing the implementation of RF-ID (Radio Frequency- Identification) tag detection using ARM7TDMI micro-controller. This is the idea and as it has always been said IDEA CREATES LEGENDS.

First and Foremost Requirements:

• ARM7-TDMI controller & ARM IDE(Integrated Development Environment)
• LCD (16*2 matrix)
• RF-ID antenna (Patch)
• RF-ID Detection Circuit.
• PC
• MIND

Attached below is the promo of what we are looking forward to do in this post.

Steps to follow:

• Write a program on ARM IDE.
• Add the necessary libraries, makefiles, startup files,link files to the project.
• Build the program.
• If there are errors go back and make sure there doesn't exist any error in the procedure or in the code.
• If there are no errors...BINGO...You are DONE with the software part. ARM IDE will create .hex extension file for dumping. Now the only thing required is to dump the program into the ARM7 controller.
• Power on ARM7, keep it in program mode (note: RED LED for Programming mode, GREEN LED for Running mode) and using "philips flash utility" JUST DUMP THE PROGRAM in ARM7 (like you are used to dump the girl/boy friends).
• Now disconnect RS232 cable between ARM7 & PC and connect RFID detector using RS232 cable.
• BOOM...Your device has already started working man...What you are waiting for. Just go and scan you RF-ID tags.

That is all we will have to do to make it work. Hope you might have liked it. If you have any doubts fill free to ask it through comments. I shall be happier to clear the same.

In the end, Thank you very much for spending your quality time on the blog. Keep visiting the blog, will be uploading more tutorials soon. Till then enjoy.

Your Friendly Neighborhood,
Mohit.
