Has anyone ported RC522 RFID reader over SPI on OP?

RC522 porting on RPi is heavily depend on gpio library of bcm2835.

I have tried porting existing RC522 project using WiringOP andorangepi_PC_gpio_pyH3 with no luck.

Best way to avoid gpio library dependency is port using user space driver using/dev/spidev0.0.

if anyone tried this or some pointer implement will be great help.

I am using latest OS (5.04) by armbian and SPI is working ( atleast spidev_testshows its working )

Did you manage to resolve the issue. I am facing the same issue despite following exact same steps as described in the link.

It works for me half a year ago, now tried it again and it do not work, same steps, just new armbian release and different board, no errors displayed, but no readings, checked my cables twice, change RC522 board, no success
