Arduino Micro + RC522

Projects Programming

Hi,

I want to read a card with Arduino micro + RC522, there is a function that I must give , pin RESET and pin SS from a Arduino Micro,

I have checked pinout of Arduino Micro and RESET is ICSP-5 and SPI SS .

Then,

#define RST_PIN ICSP-5
#define SS_PIN 10

'ICSP' was not declared in this scope

How I can say to software which pin is RESET?

ICSP-5 is interpreted as ICSP minus five.

Although a little outside my knowledge, it's my understanding that you can use any pin for the reset. So you can e.g. use

#define RST_PIN  4

and connect the reset of the reader to pin 4

just to add

reset_pin sends LOW signal to your RC522 to

a. initiate it when our system boots

b. reset your RC522 from unrecoverable state/crashed(locking up) condition
