Rc522 Proteus Library 'link' «TRUSTED»
void setup() Serial.begin(9600); // Initiate a serial communication SPI.begin(); // Initiate SPI bus mfrc522.PCD_Init(); // Initiate MFRC522 Serial.println("Approximate your card to the reader..."); Serial.println();
Why? Because the RC522 communicates via (sometimes I2C/UART) and involves complex anti-collision algorithms for reading multiple cards. Modeling that in a simulator is genuinely hard. rc522 proteus library
