Lsmod $ ls /dev/spi* You can should see the program output in Figure below. 3 Attaching NFC Module to Raspberry Pi In this testing, we connect NFC module to Raspberry Pi via SPI. The following is our wiring: NFC SCK to Raspberry Pi GPIO11 (SPI_CLK) NFC MI to Raspberry Pi GPIO09 (SPI_MISO) NFC MO to Raspberry Pi GPIO10 (SPI_MOSI) NFC NSS to Raspberry Pi GPIO08 (SPI_CE0_N) NFC GND to Raspberry Pi GND NFC 5V to Raspberry Pi VCC +5V This is my wiring implementation. com/nfc-tools/libnfc , on Raspberry Pi.
I have two NFC cards for testing so I define two variables for NFC cards. c. abtUid[0] == 0x08 ? deposit); } } } sleep(2); } exit(EXIT_SUCCESS); } Save this file. 45. Two NFC cards are set firstly included their amount. 5 Testing Now you can compile and run the program. /nfc_payment You can swap the NFC card and see the program output. The deposit amount from NFC card will be reduced after swapped. 6 What's Next? Now you can build a real application by connecting to database server and design finance model for your project.
ZIP Library. zip library. After that, you're ready to develop a program for NFC. 3 Wiring We connect NFC module to Arduino via SPI. You can see NFC module pins on Figure below. The following is our wiring: NFC SCK to Arduino Digital 13 (SCK) NFC MI to Arduino Digital 12 (MISO) NFC MO to Arduino Digital 11 (MOSI) NFC NSS to Arduino Digital 10 (SS) NFC GND to Arduino GND NFC 5V to Arduino VCC +5V My implementation for hardware wiring, shown in Figure below. 4 Reading NFC Card In this section, we build a simple app to read NFC card.
