Dear all,

I have a question and really could use your help.

At the moment I'm working on a project for RFID reader. I noticed that most of the RFID reader chips on the market are compatible with ISO14443 protocols, but they have a fifo buffer that holds the frames of the protocol. I mean, if I want to send a command like WAKEUP, or HALT, I will have to create the appropriate frame for the the command according to the ISO protocol and then transmit that frame to the fifo of the reader.

Is what I just said right?

if so, is there any library for functions that creates the frames for me, that is, for example function like this

*frame_ptr WAKEUP(void); // function that creates the frame for the command WAKEUP and returns a pointer to the frame

if there, could you please point me to them?

also is there a single RFID chip that does the framing for me, for example, if I send a byte 0xDB for example, the chip will initiate a wakeup sequence.

is there a single chip that can do this ?

thanks you so much, please I need your help as I'm very close to my graduation project delivery date.
