SPI between MFRC 531 and PIC 18f258

Forum / MIFARE and NFC Reader IC`s / SPI between MFRC 531 and PIC 18f258

    Attempt to communicate a MFRC 531 with a PIC 18f258 with SPI communication using C18, try to read an address of EEPROM memory.

    My circuit is OK because the oscilloscope data sent by the SPI are observed, the NRD and NWR pins are connected to 5 volts, A1 and NCS are connected to output pins of the PIC that set 0 logical, ALE is controlled by the PIC and is set to 0 logic before sending the data by SPI, A2 is connected to the PIC SCL, D0 is connected to the PIC MISO, A0 pin connects to MOSI the PIC. But the MFRC not respond or send incorrect data.

    Please I need a different examples of data sheet example. Can you help me ?.

    Thank you very much for your attention.
