Here is some sample code in C to use with the MCP2515:

The MCP2515 is a popular CAN (Controller Area Network) controller chip developed by Microchip Technology. It is widely used in various applications, including automotive, industrial, and medical devices. Proteus, a well-known circuit simulation software, provides a library for simulating the MCP2515 chip. In this text, we will review the MCP2515 Proteus library, its features, and its limitations. mcp2515 proteus library best

The MCP2515 Proteus library is a simulation model of the MCP2515 chip that allows users to simulate and test their CAN bus systems in a virtual environment. The library provides a graphical representation of the chip and its interface, making it easy to connect and configure. void mcp2515_init() { // Initialize SPI //
