Step through your SPI communication code line by line to verify register configuration.
(If you want me to look up current downloads, say "Search for MCP2515 Proteus library" and I'll fetch candidate sources.)
The MCP2515 works as an SPI slave device. Wire the logic terminals directly to your chosen microcontroller's primary SPI peripheral bus:
If you had Proteus open during this process, close the application completely and relaunch it. This forces the software to re-index its database and recognize the new components. Step-by-Step CAN Bus Simulation Setup in Proteus Mcp2515 Proteus Library Download-

Navigate to your Proteus installation directory and paste the extracted files into the LIBRARY folder.
When you extract the downloaded ZIP folder, ensure it contains these two essential file extensions:

If you have Proteus open, close it completely and relaunch it. This forces the software to re-index its database and recognize the newly added MCP2515 component. Verifying the Component in Proteus ISIS
