Hi there I am trying an RFID circuit.
I am on the development state of readind the H4100 read only 64bit 125KHz tag using an ATtiny2313.

Actualyy my problem is that the datas I see are not as the data sheet says.

Does anybode knows any help sites to read and learn about?

thank you.

Michael.

Sounds interesting. I'd like to know how they work too. Does it send clk and data, or manchester, or nrz? Are you bitbanging it? I've written bitbanged uart routines... read the input, shift the bit in to the answer, delay 1 bit time, repeat. We can help with that type of problem

Oh I did it,

It was a bug.

Now I can read the 64bit data and I also can verify it.

I am using the philips HTRC110 reader chip in order to comunicate with the tag.

The tag is the H4100. The data I read are in Manchester coding followed by row and collumn parity bits.

Very nice.

Michael.

Hi there
I have tried with clamshell tag 125Khz as 64bit, could it comply with HTRC110 reader chip connecting with ATMega16 by Data-IN + CLK ?

Can you pls send me the schematic for your circuit using ATtiny2313?
