The MCP_CAN library's begin() function handles the controller's initialization, requiring the CAN baud rate and your MCP2515's clock speed. While you can't run the Arduino IDE within Proteus, you can compile your code in Arduino IDE (or other IDEs) and load the resulting .HEX file into the microcontroller's properties in Proteus.
In the simulation:
In the Arduino world, the is a highly recommended choice for its stability and features:
Proteus does not include a native, pre-installed MCP2515 simulation model in its default component breakdown. Hardware developers use custom external libraries to bridge this gap for several key reasons: mcp2515 proteus library best
Alternatively, a verified mirror exists on GitHub: github.com/electronicdart/proteus-mcp2515 (check last commit date – should be within 2 years).
Several community-developed libraries have emerged to address this need:
: After creating a custom component, ensure Proteus has been restarted before use. The library cache must be reloaded for the new component to be recognized. Hardware developers use custom external libraries to bridge
BAUDRATE = 125000 ;
Route the CANTX and CANRX pins of the MCP2515 to the TXD and RXD pins of a transceiver model (like the TJA1050).

A high-quality schematic component is only half the battle. Because the MCP2515 translates Serial Peripheral Interface (SPI) commands into CAN frames, a simulation model must handle complex timing and registers. The best libraries possess three core attributes:
Link the MCP2515 INT pin to an interrupt-compatible pin on your microcontroller (such as Digital Pin 2 on an Arduino Uno) to capture incoming CAN frames instantly.
