Hi,
I am new with 13.56MHz RFID reader I have RFID reader RC522 base on MFRC522 chip. I read an write on its register without any problem , but I don't know clearly how I can communicate with Mifare Card i read https://wg8.de/wg8n1496_17n3613_Ballot_FCD14443-3.pdf and MFRC522 datasheet, I got that I should send at first Request Command REQA and wait 5ms for Answer to reQuest (ATQA).
I do this but never read any answer from tag.
this is my steps:
//**1.PERFORM A SOFT RESET**\\
//**2.turn on the antenna by enabling PINs TX1 and TX2. After a reset these pins disabled**\
//**3.Write 26h to the FIFO buffer**\
//**4.Enable Transceive Mode**\\
//**5.send data by set BitframingReg**\
//**6.read from FIFO Buffer**\
is it wrong? i should do something else?
any help would be greatly appreciated.
