Controller Area Network (CAN)
The Controller Area Network (CAN) represents an essential vehicle bus standard. It was explicitly engineered to facilitate communication between microcontrollers and devices without resorting to a central computer. The primary purpose of CAN is to enhance vehicle interconnectivity and foster swift data exchange between various systems within the vehicle.
MCP2515
The MCP2515 is an integrated circuit produced by Microchip Technology, constructed to function as a stand-alone CAN controller. It exhibits compatibility with an SPI (Serial Peripheral Interface) which makes it versatile in various applications. Although its primary use is in automotive industries, it is also used in a variety of other control applications.[1]
The MCP2515 bridges the connection between the CAN protocol and the SPI protocol by receiving CAN messages and translating them into SPI data, allowing the microcontroller to interpret the information. Similarly, it transforms SPI data into CAN messages for transmission.[2]
The MCP2515's operational details include its capacity to support CAN 2.0A and B, drawing attention to its alignment with established CAN standards and equipping it for both basic and extended frame format usage.[3]
