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
Click the button at the bottom-left of the Proteus interface to start the simulation. The Virtual Terminal window should pop up displaying "System Ready: Scan your RFID Card...". Troubleshooting Common Issues:
Click on the button (the "P" icon on the left toolbar). In the Keywords search bar, type RC522 or RFID .
Some custom libraries require you to link a .TXT or .HEX file containing a dummy UID (e.g., 10 23 45 67 89 ). rc522 proteus library

: Navigate to your Proteus installation directory. To simulate the RC522 RFID module in Proteus,
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)
The you plan to code for (Arduino, PIC, or STM32)?
: Most versions effectively simulate SPI communication , which is the standard interface for the RC522 module. The Virtual Terminal window should pop up displaying

Proteus is known for its unique ability to simulate microcontroller code (specifically Arduino HEX files) alongside electronic components. However, out of the box, Proteus does not include a native RC522 model. Enter the third-party RC522 Proteus Library: a custom simulation model that bridges the gap, allowing you to simulate your entire RFID project before soldering a single component.
: For the new components to appear, you must fully restart the software.
