If simulation fails repeatedly, use a physical MCP2515 module ($5 on Amazon) with your development board. Debug using a logic analyzer.


Before diving into the library, let’s quickly recap the component:

In a real circuit, the MCP2515 communicates with a microcontroller (e.g., Arduino UNO, PIC18F, STM32) via SPI. The microcontroller sends/receives CAN messages through the MCP2515.

Yes, the library works with any microcontroller that supports SPI. You can simulate STM32F103, PIC18F458, or even an ESP32 (through a compiled HEX file).
