Library !!hot!! — Rc522 Proteus

But what happens when you don't have the hardware yet? What if you want to debug your code before soldering?

Copy the downloaded RC522.IDX and RC522.HEX (or .LIB ) files into the library folder. If you only have a .HEX and .IDX , ensure both are present; missing one will cause a load error. rc522 proteus library
