RFID tag for communication with u2270b

[uc_guy]

rfid reader circuit

Can anyone tell me, which mode does the U2270 start operation in? Manchester or bi-phase? How to select the mode? Also, how to transmit the opcodes required by the Tag?

TIA

Well, The U2270b is suitable for biphase and manchester. I think than you don´t need select the operation mode. You only receive a stream of bits and you should make a program in the microcontroler which receive this information like you want it. It only can effects in the way that you design the code in the microcontroller that is connected to the U2270b.
I would like someone else responses this question for seeing soe different opinions.

i want to design a rfid reader using microcontrioller only...is it possible to do using no other reader ic?

EDIT: sorry it was a dummy question...

 

[petrovicjose]

write rfid schematic

It is no possible, because the reader is the interface between the microcontroller and the tag. Its function is to adaptate the signal level to the ttl voltage, synchronizes the transpoder rate with the microntroler speed, check if there is not bit errors, demodulates the signal.......

Thanks, luben111 for your coperation.

rfid reader ic

U can also try to get some samples for free at www.ti.com
they will send u 2-3 samples for free...
but dont try to cheat them.....they can stop giving the samples for ur country.

Colleagues,

Which RFID reader chip puts out the most power?

My crude understanding is that power translates into current that the chip can put out on the antenna coil. According to the datasheets, EB4095 can put out 250mA and U2270 can put out 200mA. I know from the app notes that it’s possible to make the reader more sensitive by adding an amplifier to the input. Is it also possible to make the reader more powerful by adding an amplifier (power amp) to the output? If so, what are the limits set by bodies like TUV, CE, FCC, GOST/RST etc?

Thanks,
Nick

P.S. A lot of RFID reader chips have been mentioned here already, so I don’t think I’m hijacking this thread.

hi luben
which compiler do u use for copiling your code, i want to edit it bu in CCS (PICC) i can't compile it.

Hello again,

Anybody knows what is the bit period of the data output from the u2270b??

Thanks everybody

Pls google the chip FM1702. This is cheap.

Hello Luben111,

Thanks for the schematic and everything. I want to modify the circuit. I need to read the tag id from the reader from my computer through the serial port. Is it possible to do so? Is there any source code or the way to decode the transpoder? Please help me. Thanks!!

Hello Chentzin and Luben111 or anybody around

I am olso planning to use the U2270B, and parallel port for connection for PC to the reader. However, am bit confuse over the port allocation. Parallel Port is make up of 3 ports, data, status and control. for successful data transfer, so which control, status (handshaking purpose) and data line of the U2270B can be connect to the parallel port.

Thanks and cheers

Hi guys

why dont you take at look at the ID-12. It takes all the work out of it. A 25x26x7mm module with integral antenna. Range 12cm with ISO card.

build my own rfid reader

thank for all
I use HTRC110

Re: RFID reader IC

Hi

We recently used the HTRC110 with this driver http://www.embedded-code.com/source-code/rfid/125khz-rfid-readers/htrc110-em4102-rfid-reader-driver

The doc for it has loads of info **broken link removed**

Re: RFID reader IC

I realize this is an old thread but has anyone used the U2270B with TK5551 tags, if so would you be able to provide some assistance with some basic source code for communications?

Re: RFID reader IC

Hi

from your experience what is the maximum reading distance that can be achieved in an RFID system that works on 13.56MHz?

Thanks
