Hi, i just got my RPI3 and wanted to make a project with RC522, i installed raspbian the latest version (2016-11-25-raspbian-jessie), i followed alot of blogs and sites, and still have the same problem, it's not showing anything when executing the code. i looked online and in forms and i think it spi problem, cause even after enabling the spi, i found this in a blog :
$ dmesg | grep spi [ 5.408904] bcm2708_spi 20204000.spi: master is unqueued, this is deprecated [ 5.659213] bcm2708_spi 20204000.spi: SPI Controller at 0x20204000 (irq 80)
but when i do it in my terminal i get nothing, with
lsmod spi_bcm2835 6678 0
and
ls /dev/spi* /dev/spidev0.0 /dev/spidev0.1
i did all the updates and upgrade, also i did firm update, I installed the SPI-Py , python-dev , checked my wires and still got nothing.
Thank you for the help.
