Close all active instances of Proteus and relaunch the software. This forces the device database to re-index, adding the updated module to your component picker list. Pinout and Connection Diagram in Proteus
Move the .IDX and .LIB files into the LIBRARY folder. rc522 proteus library updated
However, for years, simulating the RC522 in Proteus was a nightmare. Older libraries were buggy, lacked proper SPI protocol handling, or simply crashed the software. This led to a common frustration: “My code works on hardware, but not in simulation.”
The updated RC522 Proteus library is a specialized simulation tool that allows engineers and students to model Radio Frequency Identification (RFID) systems digitally before building physical prototypes. Based on the chip designed by NXP, this library simulates a highly integrated reader/writer that operates on the 13.56 MHz frequency.
