Help me select MCU and programming language for a RFID project

[Aymanz87]

rfid project

I am building an integrated RFID system capable of quickly identifying objects by their RFID tags. The system will be able to read and write Tags. Read data will be store in a Database through a Middleware.

I intend this system to be installed in Libraries. By automatically identifying the
Books and collecting their info ...

At the bottom u will find pix for the system block diagram and flowchart


I was wondering :

what MCU to use and how to make it support graphical LCD?

How the communication between PC and reader will work ... to read data and write tags ... what programing language to use ?

what is the construction in the frame pattern sent between Tag and Reader?

Do u got any links or books that can help me through this project?

First of all i suppose you ll use 860-950 Mhz. Cos identifying objects from a distance.

Second your MCU should be powerfull enough to control Rf modul (command sets for tx, and parse operations for Rx from fr modul and compare operations in MCU)

for eproom i advice you max 25 AA series (1 Mbit, you can store up to 5000 records with 96 bit EPC and RSSI and some timestamp etc.)

Any way even with pic 18 series ll be sufficent from my experience. you may develop your own embedded code in c(mcu side) and c# at middleware side.

Did you ever considered antennas??

Good luck

rfid project book

Thanx ....

But I am working at 13.56 Mhz .. I hope it can identify the book from 0.5 meter at
least

I want to use Atmel microcontroller not pic .. What do u recommend ?

Is there open source codes for interfacing between PC and MCU ?

I can not find the EEPROM ... MAX .. 25 ..AA , Can u send me a datasheet or link ?

About the antenna ... I think i will use loop antenna but is it possible to integrate the antenna with the PCB at 13.56 MHz

Thanx again

c# rfid reader

Use micrcontroller MSP430. It is basically manufactured for RFID application

I think if u extend your self to FPGA you will be more strong in your work

rfid project download with source code

8051 may be OK.
13.56M 14443, or 15693

0.5m is a long distance for 13.56M

15693H and antenna may be .

tag pasif rfid

ll u use this system also for counting?? or one tag ll be read at a time?
you ll also need some tag singulation algorithms.

And also as it said before .5 meters is a long distance...

rfid project using microcontroller

Thanx ... Your Replays is very useful ..

I know i need some kind of anti collesion protocol ... but i still searching abt it .... This is my first time to work with rfid .. and this is my graduation project ... I just want to understand how the communication works between diff component of the system ( Tag & reader IC - Reader IC and MCU - MCU and PC ) ... like defining the frame pattern used in each case ...

I understand 13.56 mhz can make .5 m com distance ... but do u think it will provide enough distance for Library books inventory ?

rfid project using microcontroller (e-book)

U can not use this kind of system for inventory management. u can just use it for bargaining and returning of books. if you want to construct such and inventory management of books, you have to have a different way on UHF band(pasif) Cos its cheapest.

Good luck

Hi Amanz87,

I have done the RFID project before, pls c below my project explanation.

USB interface between PC & MCU to store User Data. This requires a software, i have developed the software by using VB6.

Serial communication between RFID reader & MCU.

If u interseted, u can reply to my e-mail address. nickykim_2000@yahoo.com

Hello!

1. MCU:
If you want it to be connected to a PC, you will need through USB, you will
need 1 USART.
If your RFID reader module is a serial device, then you'll need another USART
EEPROM works usually in I2C, therefore you will need a I2C capable USART.
Then finally if you want to use a graphical LCD, there are many options.
Some LCDs allow SPI input, in which case you need another USART.

The PC USB device works probably in UART mode
The EEPROM works in I2C
Let's assume that the LCD will work in SPI
Let's assume that the RFID reader works in one of the above 3 modes.

You can of course use a single uart and reconfigure it each time, but
programming will be a headache.

You may want to use a device with manu UARTs. The MSP430F54xx
may be an option (4 UART engines).

2. Communication between PC and USB:
If you use a TI device (the above MSP430F54xx) combined with their
USB chip (TUSB3410), then you have a full working source code for the
PC application. I recently used it, it works right out of the box.
When the hardware is done, send a byte and you will receive it on hyperterminal.
Send a byte from a PC application to ComX (the virtual port corresponding to
your device) and your device will receive it.
This document includes the schematics, for this application. **broken link removed**.
And in the above URL, if you replace pdf by zip, you will download the slaa276.zip
archive which contains the source code of the application.

3. "what is the construction in the frame pattern sent between Tag and Reader?"
I don't understand your question. If you meant the pattern of the bytes exchanged
between the tag and the reader, I think you should read the docs. All the maker
have probably their own standards, therefore no standards.

4. I don't know any book that would help you for that particular project.


Now a bit more about the MCU choice:
You want to use a graphic LCD, but that's not enough to choose your MCU.
The LCD I am using right now (2048 x 1152) is a graphic LCD. On my desk,
I have also 128x32 graphic LCDs. **broken link removed**.
So you should also tell us the resolution and the depth (bits per pixel).
By experience, I can tell you that with 25 MHz MCU, you can easily drive
a 240 x 160, 5 bits per pixel LCD like **broken link removed**.

Thanks guys for the advice I am going to wrk day and night to make this project a succes
