RFID reader RC522 SPI usage - Raspberry Pi Forums

-

hello,

i'm trying use rfid reader pi4j libraries, no success.

connected through spi interface (miso-mosi, sck , sda). have spi ports correctly opened on raspberry.
cannot start think how manage it, no way know how read reader.

has solved problem or address me right road?

thanks

why sda?

should /ce0 or /ce1, , need connect gnd

also, if rfid reader has 5v outputs, need divide miso down 3v3
