The open-source hardware community came to the rescue. Several developers have reverse-engineered the RC522’s SPI command set and created a for Proteus 8 and 9.
: Close any active Proteus windows and restart the software to refresh the component list.
Connect the RX/TX pins of the Virtual Terminal to the TX/RX pins of the Arduino to see debug logs. rc522 proteus library
Simulating the RC522 in Proteus provides several advantages: No risk of damaging components by miswiring.
The RC522 is a 3.3 V device. A 5 V to 3.3 V level shifter is recommended when interfacing with 5 V logic microcontrollers to avoid damage. The open-source hardware community came to the rescue
Note: The ProgramData folder is hidden by default in Windows. Enable "Hidden items" in your File Explorer view settings to access it.
Locate your Proteus installation folder (typically C:\\Program Files (x86)\\Labcenter Electronics\\Proteus 8 Professional\\DATA\\LIBRARY ). Connect the RX/TX pins of the Virtual Terminal
A complete simulation setup typically requires the following parts:
Here’s the fun part. Let’s wire the virtual RC522 to an Arduino Uno (or a PIC/STM32).
