Rc522 Proteus Library -
The Complete Guide to the RC522 Proteus Library: Simulating RFID in Arduino Projects
Introduction
The RC522 is arguably the most popular RFID/NFC module for hobbyists and embedded engineers. Based on the Philips MFRC522 chip, it operates at 13.56 MHz and allows you to read and write data to tags like Mifare Classic 1K and 4K. When building complex systems—like access control panels, inventory trackers, or smart payment simulators—testing code directly on hardware can be tedious and expensive. This is where Proteus Design Suite and the RC522 Proteus Library become essential.
Since Proteus does not include the RC522 by default, you need to download a dedicated library folder (typically containing .LIB, .IDX, or .MD5 files). How to Add RFID Module in Proteus - Cykeo rc522 proteus library

If bootloader unloacked allowed:NO
what should I do to unlock?
i did not find the “Flashtool-drivers.exe” in the downloaded “SE Bootloader_Unlocking_Relocking_1.6.rar”.
is it the one in the libs folder? if so, it asks for java runtime or smth, like “please define EXE4J_JAJA_HOME…”
-im using 64 bit win7.
help me
i cant not get unlock code… pls send to me
