Proteus Library — Rc522

/* Emulation MCU runs as SPI slave */

Once the library is installed and the code is loaded, you need to "add" a virtual card.

When the microcontroller scans, it will detect the virtual card with the UID you entered.

Pro Tip: To simulate "removing" the card, pause the simulation, change the UID field to 00 00 00 00 or uncheck a "Card Present" box, then resume. rc522 proteus library

Here’s the fun part. Let’s wire the virtual RC522 to an Arduino Uno (or a PIC/STM32).

The Wiring (Same as physical hardware):

The "Secret Sauce" in Simulation: When you place the RC522 in Proteus, double-click it. In the "Advanced Properties" field, you need to attach the HEX file for the model itself. Point it to the RC522.HEX file you downloaded. /* Emulation MCU runs as SPI slave */

Without this HEX file, the virtual chip has no "brains" and will return only zeros.
