Proteus Library - Rc522

⚠️ : RC522 is 3.3V only . Use a POWER = 3.3V terminal in Proteus, not 5V.

The RC522 module communicates primarily over the Serial Peripheral Interface (SPI) bus. Here is how to wire the virtual RC522 module to an Arduino Uno within Proteus for a standard simulation setup. RC522 Pin Name Arduino Uno Pin Description SPI Slave Select (Chip Select) SCK SPI Serial Clock MOSI SPI Master Out Slave In MISO SPI Master In Slave Out IRQ Unconnected Interrupt Request (Not needed for basic setups) GND Ground Connection RST 3.3V VCC (3.3V) Power Input (Note: Physical RC522 is not 5V tolerant) Adding Simulation Visual Aids

A simulation project like this is ideal for learning because you can observe the full interaction: the microcontroller polling the RC522, the virtual card ID being injected, and the final access decision displayed on the screen. rc522 proteus library

The ability to simulate an RFID system before committing to physical hardware is a game-changer in electronics design. For engineers and hobbyists alike, the unlocks this capability, enabling virtual testing of 13.56 MHz RFID projects. This guide provides everything you need to find, install, simulate, and troubleshoot with the RC522 module in Proteus.

Take the downloaded .LIB and .IDX files and copy them into the LIBRARY folder. If your package also contains a .HEX file (the RFID firmware model), do place it in the Proteus system folder; instead, keep it in a dedicated project folder that you will reference later. ⚠️ : RC522 is 3

To simulate the RC522 in Proteus, you need a custom library component. Several community-driven libraries exist. Steps to Install the Library:

You connect a digital toggle switch or a logic state state-generator to the "Trigger" or "Control" pin of the virtual tag. Here is how to wire the virtual RC522

You pasted the .LIB and .IDX files into the wrong folder path. Double-check your active directory or check the ProgramData hidden directory route.
