For now, the community RC522 Proteus library remains a hidden gem for students. It is not perfect, but it is powerful enough to teach 90% of RFID concepts without physical hardware.
: Allows for testing both valid and invalid RFID tags using a Virtual Terminal to input tag data. Communication Interface : Typically simulates the SPI (Serial Peripheral Interface) protocol used by the real-world module. Arduino Integration : Seamlessly interfaces with Arduino libraries (like Miguel Balboa's MFRC522 rc522 proteus library
spi_write(CommandReg, PCD_Idle); spi_write(FIFOLevelReg, 0x80); // flush FIFO spi_write(FIFODataReg, REQA); // or appropriate command sequence spi_write(CommandReg, PCD_Transceive); wait for IRQ or poll CommIrqReg for RxDone read FIFO to get response (UID) For now, the community RC522 Proteus library remains
