Sarah leaned over his shoulder, squinting at the schematic. "You’re using the generic SPI display model for the communication module. That won’t work. You need the specific controller chip."
To make the simulation functional, you will also need to include an MCP2515 library in your code (e.g., Arduino IDE). Highly recommended options available on GitHub include: mcp2515 proteus library link
The MCP2515 library provides high-level control over the hardware, abstracting the complex register configurations needed for CAN communication. Sarah leaned over his shoulder, squinting at the schematic
