The RC522 is a popular RFID reader/writer module widely used in various applications, including access control, inventory management, and payment systems. Proteus, a powerful simulation software, allows designers to simulate and test their circuits before building a physical prototype. In this post, we'll explore the RC522 Proteus library, its features, and how to use it effectively.
Most free RC522 libraries for Proteus were cracked or created for . If you are using Proteus 8.13 or the new Proteus 9, the simulation will crash with a cryptic error like "FATAL: [U1_MFRC522] Model DL mismatch." rc522 proteus library
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. The RC522 is a popular RFID reader/writer module
