PIC18F458 (has a built-in CAN engine) or ATmega328P. CAN Controller (If using ATmega): MCP2515.

Restart Proteus. Search for "MCP2551" in the pick-device window. Step-by-Step Circuit Design in Proteus

Obtain the MCP2551 library files (usually a .lib and .idx or a .lbr file). Even with the best library, you might encounter

The MCP2551 library in Proteus provides a virtual representation of the IC, allowing users to simulate and test CAN bus communication in their designs. The library includes:

Finding a native Proteus library for the MCP2551 CAN Transceiver

: Users have noted that while logic might work in simulation, physical hardware requires precise bit timing (often requiring exact crystal frequencies like 16MHz) and proper 120-ohm termination resistors to function in the real world. This link or copies made by others cannot be deleted

To install the library correctly:

Proteus does not always include the MCP2551 in its default "Starter" libraries. You typically need to download or verify the following:

Connect the TXCAN and RXCAN pins of the MCP2515 to the corresponding TXD and RXD pins on the MCP2551.

The MCP2551 is a CAN Transceiver. Its job is to convert TTL logic (0V/5V) from a microcontroller (like PIC or Arduino) into the differential voltage (CAN High/CAN Low) required for the bus.
