#define RST_PIN 9 #define SS_PIN 10
If your simulation fails, check for these common configuration issues:
Ensure the .LIB and .IDX files are in the core ProgramData directory, not the user documents directory.
When you right-click the RC522 module in your schematic and select , you will see a field labeled Program File or Card Data File . rc522 proteus library
Double-click the virtual Arduino, upload your compiled script, and press the Play button in the lower-left corner of Proteus.
Double-click the component to add it to your devices list, then click on your workspace to place it. 4. Schematic Interface: Connecting RC522 to Arduino Uno
Note: You must ensure your library’s pin mapping matches the connections in your Proteus simulation. 4. Programming and Simulating the RFID System #define RST_PIN 9 #define SS_PIN 10 If your
: You will typically find two or three files in the download: , and sometimes a model file. Paste into Proteus Folders Navigate to your Proteus installation folder (usually
Locate your Proteus installation folder (typically C:\\Program Files (x86)\\Labcenter Electronics\\Proteus 8 Professional\\DATA\\LIBRARY ).
Connect the RX/TX pins of the Virtual Terminal to the TX/RX pins of the Arduino to see debug logs. Double-click the component to add it to your
Let’s get the bad news out of the way first. If you open Proteus and search for "RC522" or "MFRC522," you will find... nothing. Just an empty void where your RFID reader should be.
: Allows for testing both valid and invalid RFID tags using a Virtual Terminal to input tag data. Communication Interface : Typically simulates the SPI (Serial Peripheral Interface) protocol used by the real-world module. Arduino Integration : Seamlessly interfaces with Arduino libraries (like Miguel Balboa's MFRC522
Note: The ProgramData folder is hidden by default in Windows. Enable "Hidden items" in your File Explorer view settings to access it.
Since the MFRC522 is not a default component in Proteus 7 or 8, you must manually add the library files.
