Rc522 Proteus Library

Functional testing without hardware model

Pick Arduino Uno , MFRC522 , Buttons , LCD (optional), and LEDs .

Before diving into the library itself, we need to understand the value of simulation.

: If you're using a library from a newer Proteus version, open the .LIB file in Notepad and change the version number in the second line to match your Proteus version.

#include #include #define RST_PIN 9 #define SS_PIN 10 MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance void setup() Serial.begin(9600); SPI.begin(); mfrc522.PCD_Init(); Serial.println("Scan RFID Tag..."); void loop() if ( ! mfrc522.PICC_IsNewCardPresent()) return; if ( ! mfrc522.PICC_ReadCardSerial()) return; // Show UID on serial monitor Serial.print("UID tag :"); String content= ""; for (byte i = 0; i < mfrc522.uid.size; i++) Serial.print(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " "); Serial.print(mfrc522.uid.uidByte[i], HEX); Serial.println(); mfrc522.PICC_HaltA(); Use code with caution. Step 4: Simulating in Proteus rc522 proteus library

Since Proteus does come with a built-in RC522 model, you have two practical options:

// Select one card if (!mfrc522.PICC_ReadCardSerial()) return;

Test extreme conditions and faulty wiring scenarios safely without blowing out real ICs.

Often, the library includes a component that represents the RFID card, which can be toggled to simulate a "card present" signal. Coding and Testing (Arduino IDE) Functional testing without hardware model Pick Arduino Uno

Ensure you do not connect the RC522 to 5V in your physical circuit, although Proteus handles this gracefully.

Connect the 3.3V and GND pins of the RC522 module to the corresponding power sources in the schematic.

Double-click the Arduino in Proteus, and in the "Program File" option, select the .hex file. Run the simulation.

To add the RC522 component to your Proteus workspace, follow these step-by-step instructions: Step 1: Download the Library Files #include #include #define RST_PIN 9 #define SS_PIN 10

Search for a trusted repository (such as GitHub or engineering forums) hosting the custom RC522 library files. The download package typically contains two vital files: RC522Library.IDX (Index file) RC522Library.LIB (Library file)

Go to the RC522 properties and ensure the clock frequency matches your microcontroller's expected speed (typically default settings work best). Turn off other heavy running background programs on your PC to give Proteus adequate processing headroom.
