Usage

  • Process
    1. Initialization
    2. Detected and bind card
    3. Read or write data

C:


  fpioa_set_function(RFID_CS_PIN, FUNC_GPIOHS0 + RFID_CS_HSNUM); // RFID_CS_PIN: 20;
  fpioa_set_function(RFID_CK_PIN, FUNC_GPIOHS0 + RFID_CK_HSNUM); // RFID_CK_PIN: 21;
  fpioa_set_function(RFID_MO_PIN, FUNC_GPIOHS0 + RFID_MO_HSNUM); // RFID_MO_PIN: 8;
  fpioa_set_function(RFID_MI_PIN, FUNC_GPIOHS0 + RFID_MI_HSNUM); // RFID_MI_PIN: 15;

  gpiohs_set_drive_mode(spi_io_cfg.hs_cs, GPIO_DM_OUTPUT);
  gpiohs_set_drive_mode(spi_io_cfg.hs_clk, GPIO_DM_OUTPUT);
  gpiohs_set_drive_mode(spi_io_cfg.hs_mosi, GPIO_DM_OUTPUT);
  gpiohs_set_drive_mode(spi_io_cfg.hs_miso, GPIO_DM_INPUT);

  // detected card
  PcdRequest(0x52, type)

  // auth and bind...

  // read or write 16 bytes data from sector 0x11
  PcdWrite(0x11, w_buf)
  PcdRead(0x11, &r_buf)

MaixPy:


  # 20: CS_NUM;
  fm.register(20, fm.fpioa.GPIOHS20, force=True)
  # set gpiohs work mode to output mode
  cs = GPIO(GPIO.GPIOHS20, GPIO.OUT)

  # RFID_SCK: 21; RFID_SI:8; RFID_SO: 15;
  spi1 = SPI(SPI.SPI1, mode=SPI.MODE_MASTER, baudrate=600 * 1000,
          polarity=0, phase=0, bits=8, firstbit=SPI.MSB, sck=21, mosi=8, miso=15)

  # Create an object of the class MFRC522
  MIFAREReader = MFRC522(spi1, cs)

  # detected and auth, bind...

  # read or write 16 bytes data from sector 0x11
  MIFAREReader.MFRC522_Write(0x11, data)
  MIFAREReader.MFRC522_Read(0x11)
