关于nfc近场通讯模块的使用

求助nfc近场通讯模块micropython怎么用（microbitV2)
这段代码会报错：

from microbit import *
from time import sleep
import PN532
i2c.init(freq=100000,scl=pin16,sda=pin12)
nfc=PN532()
nfc.begin()
while True:
    if nfc.scan():
        print(nfc.read_uid())
复制代码

Traceback (most recent call last):
  File "main.py",line 1,in <module>
  File "<string>",line 96,in <module>
  File "<string>",line 14,in begin
  File "<string>",line 87,in write_command
  File "<string>",ling 90,in write_to_addr
