Arduino, Raspberry Pi) to send data to one or more peripheral devices like SD cards and sensors quickly over short distances. * The reader can be found on eBay for around 5 dollars. SPI is one of the most popular communication peripheral used by microcontrollers (eg. * PICC (Proximity Integrated Circuit Card): A card or tag using the ISO 14443A interface, eg Mifare or NTAG203. * PCD (Proximity Coupling Device): NXP MFRC522 Contactless Reader IC * Uses MFRC522 - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT. * Dump block 0 of a MIFARE RFID card using a RFID-RC522 reader I havent run it with a SPI device, but have hooked it up to logic analyzer to confirm. I couldnt quite get the syntax right for the address of the SPI data register, so I did something ugly. The problem is that if the memory card is inside, I would see any response on Serial monitor when RFID device is scanned, or there would be error message: "MIFARE_Read() failed: The CRC_A does not match." I have a proof of concept of using DMA to do a SPI block write on the ZERO. Therefore I used pin 8 as SS pin for my RFID-RC522. I have a similar problem with the same configuration.Īfter reading this and similar threads, it was quite obvious that pins 4 and 10 can not be used.
