| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | | The library files were not copied to the correct directory. | Re-check the file copy step and ensure you are targeting the correct LIBRARY path. | | Simulation stalls or freezes | Missing .HEX file for the microcontroller or incorrect path. | Ensure the .HEX file is correctly linked in the microcontroller's properties. | | No data appears on the LCD | Incorrect wiring or LCD contrast issue. | Double-check all connections, especially the contrast pin (pin 3) which should be connected to a potentiometer. | | SPI communication errors | Data lines (MISO, MOSI, SCK) are miswired. | Verify that the SPI pins on the RC522 are connected to the correct pins on the microcontroller (e.g., for Arduino Uno: D13=SCK, D12=MISO, D11=MOSI). | | No card detected | The RC522 library model might not support automatic card simulation. | You may need to manually trigger a card read in the model's properties, or the simulation environment may require an associated script to emulate a tag. | Note: If you cannot find the Data folder,
