RFID module and MCS 51 interfacing

[bianchi77]

Hello everyone,

Does anybody have experience with this module interfaced with MCS51 ?
Any links or code example will be appreciated .

**broken link removed**

Thank you

Can you post the datasheet of the RFID module? Does it have TTL Outputs?

Read this http://micheljansen.org/blog/entry/408

It says mifare rfid systems has serious security flaws.

Yes. that is what I was looking for. Everything is mentioned in it. What is the problem(s) you are facing?

My question is,
Do I have to send init code ?
or just send the command via my TX pin on MCS51 and receive ( read the response ) from RX pin ?
Do you have any experiences / experiments with this module or similar module before ?

Thanks

RFID command

No. I don't have experience with this module or similar module. It is mentioned in the datasheet you sent about how to send the command.
See the attached image. the format should be as shown in the image.

I tried to send 01 command but can not get the response, I'm using Cypress currently here's the code :

do {

 

        UART_1_PutChar(0x61);
    

        Delay10msTimes(50);
      

        /* do a read char, if 0, send 0x01 again, else can start decode the reponse */

        /* This is assuming RX to the UART is between 1 and 0xFF */


        ucResponse = UART_1_cReadChar();
		
		Delay10msTimes(200);
		
		// Set LCD position 
        UART_1_PutChar(ucResponse);
		
	  

      }while (ucResponse == 0);

I don't understand why I can not get response from :
ucResponse = UART_1_cReadChar();

You have to send 1 byte command.
