Rc522 Proteus Library Page

To simulate the RC522 RFID module in Proteus, you must manually add third-party library files, as it is not included in the standard Proteus installation. 1. Downloading & Installing the Proteus Library

Error 3: “VCC pin out of range” Warning

Cause: Feeding 5V into the VCC pin.
Fix: Use a 3.3V power terminal. If your real project uses a level shifter (because Arduino outputs 5V on MOSI/SCK), simulate that as well using a logic level converter component in Proteus. rc522 proteus library

Locate Installation Folders: Navigate to your Proteus installation directory, usually found at C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY. To simulate the RC522 RFID module in Proteus,

Want to test different cards? Most advanced libraries allow you to: ⚠️ Many pre-made RC522 libraries are partial –

• Windows 64-bit: C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY
• Windows 32-bit: C:\Program Files\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY

⚠️ Many pre-made RC522 libraries are partial – they simulate only basic UART/SPI responses, not full anti-collision or MIFARE commands.

• SDA (SS/Slave Select): Connects to a digital output pin on the microcontroller.
• SCK (Serial Clock): Connects to the SCK pin of the microcontroller.
• MOSI (Master Out Slave In): Connects to the MOSI pin.
• MISO (Master In Slave Out): Connects to the MISO pin.
• IRQ (Interrupt Request): Often left unconnected in basic simulations, but can be used for interrupt-driven detection.
• GND: Ground.
• RST (Reset): Connects to a digital output pin for hard reset.
• 3.3V: Power supply. Note: While the module operates at 3.3V logic, the simulation model is generally tolerant of 5V logic inputs from an Arduino, though in a strictly physical design, logic level shifting is recommended.

6. How to Simulate

1. In Proteus, double-click the Arduino Uno.
2. Upload the .hex file of the code above (You can get the hex file from Arduino IDE by holding Shift and clicking Compile, or checking the "Show verbose output" preference).
3. Play the simulation.
4. Interaction: In the RC522 component in Proteus, there is usually a small button or a property to "Place Card." You might need to click on the module or use a virtual card object provided in the library to trigger the "Card Present" event. Check the component properties by right-clicking it -> Edit Properties to see available card slots.
