: In simulation, you do not need a physical CAN transceiver. The MCP2515 model can loopback internally or communicate via a direct wire between two MCP2515 models’ CANH/CANL pins (but most third-party models only support loopback mode for simulation stability). Sample Arduino Sketch (for Proteus Simulation) #include <SPI.h> #include <mcp2515.h> MCP2515 mcp2515(10); // CS on pin 10
