NXP的NFC读卡器PNEV512R(https://www.nxp.com/products/rfid-nfc/nfc-hf/nfc-readers/explore-nfc-exclusive-from-element14:PNEV512R)与我的新raspberry pi 4不兼容
内核:

为了安装所需的软件,我遵循本手册:https://github.com/svvitale/nxppy
安装没有任何故障。但即使是Mifare的实例化也会引发一个例外
Python代码:
import nxppy
mifare=nxppy.Mifare()
例外情况:
nxppy.InitError: Nxppy: Unknown Error from Undefined Component
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "nfc.py", line 3, in <module>
mifare=nxppy.Mifare()
SystemError: <class 'nxppy.Mifare'> returned a result with an error set
SPI当然打开了。^^我用loopbacktest测试了接口:https://elinux.org/RPi_SPI
所以SPI正在工作。在我的Raspbarry Pi 3B+上,一切正常。现在我正在寻找解决这个问题的方法
