Using RFID MFRC522 on SPI1_3CS

[benni26]

Hi,

I am trying to get the RFID-reader RC522 working on SPI1. By default SPI0 is used, but since I am using this display https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A) the default SPI port is allready used.
I added the following line in the boot/config.txt
dtoverlay=spi1-3cs

and ls /dev/spi* shows
/dev/spidev1.0 /dev/spidev1.1 /dev/spidev1.2

But I cant get it working. Do you have any Idea?
