Im trying to connect a RC522 (RFID reader) to a RedBear Blend Mirco, but I don't see the NSS and SCK labels on the pin out. Anyone have a suggestion for a work around or know which connections these are supposed to be?
Thanks
NSS (aka CS/SS - chip select / slave select - different names for same) can be any pin on the microcontroller - it's just a GPIO pin that has to be brought low while communicating with the SPI device, and raised when not communicating with it.
SCK pin looks like it's lableled CLK on that pinout?
