Do not confuse the RC522.HEX simulation model with the Arduino firmware HEX file. The library model emulates the RC522 chip itself; the Arduino HEX runs your custom sketch.
Note: You must ensure your library’s pin mapping matches the connections in your Proteus simulation. 4. Programming and Simulating the RFID System rc522 proteus library
Open Proteus → Pick Devices (P) → Search for "RC522" . If installed correctly, the RFID module will appear in the results. Do not confuse the RC522
Most libraries simulate card detection by utilizing interactive buttons or a virtual terminal to mirror UID reads. How to Download and Install the RC522 Library in Proteus rc522 proteus library
Note: If you cannot see the folder, you may need to enable "Hidden Items" in your file explorer.
: Avoid the wait for shipping and the risk of "frying" components during initial prototyping. How to Install the RC522 Library in Proteus
