Plug the Qwiic NFCPROM into the FPGA Helper using a Qwiic cable and run this python script on the FPGA Helper board:

import board
import busio
i2c = busio.I2C(board.SCL, board.SDA)
while not i2c.try_lock():
    pass
result = bytearray(32)
i2c.writeto(83, bytes([0x00, 0x00]), stop=False)
i2c.readfrom_into(83, result)
print(result)

 If you save that to the board as boot.py, you should get a boot.txt file something like this:

Adafruit CircuitPython 4.0.0-alpha.1-4-gf09537b-dirty on 2018-10-01; Steiert Solutions FPGA Helper with samd21e18
