CAN buses require a 120-Ohm termination resistor at both ends of the bus line. Place a 120-Ohm resistor across the CANH and CANL lines in your simulation schematic to prevent signal reflection errors. Configuring the Proteus Simulation Settings

Which (e.g., PIC18F, Arduino, STM32) are you connecting to the MCP2551? What version of Proteus are you currently using?

The you plan to use (e.g., MPLAB XC8, MikroC, Arduino IDE).

The MCP2551 is a high-speed CAN (Controller Area Network) transceiver from Microchip. In the Proteus electronic design automation (EDA) environment, users often look for an “MCP2551 library” to simulate circuits that include this transceiver. This piece clarifies what the MCP2551 is, what to expect from Proteus support, typical simulation limitations, and practical steps and alternatives for using or adding MCP2551 functionality in Proteus.

Implementing and Simulating the MCP2551 CAN Transceiver in Proteus

Ensure your microcontroller clock frequency in Proteus exactly matches the frequency defined in your compiler firmware. Mismatched baud rates will cause the virtual CAN controllers to enter an error-passive state, preventing the MCP2551 from broadcasting data.
