Wiring and Quick Setup

Getting started with the MCP2515 module is straightforward. Follow these general steps to connect the module to a microcontroller:

• Power: Connect 5V and GND to the module power pins.
• SPI signals: Connect SCK, MOSI, MISO and CS (chip select) to your microcontroller SPI pins.
• Interrupt: Connect the INT pin to a digital input if you want interrupt-driven message handling.
• CAN bus: Connect CAN_H and CAN_L to the CAN network via the screw terminal or DB9 connector. Use proper termination resistors (120 ohm) at each end of the bus.
• Install a compatible MCP2515 library and example sketches or scripts for your platform, then test with a second CAN node or a CAN analyzer.

Software and Libraries

The module is supported by multiple open-source libraries for Arduino and Linux platforms. These libraries provide functions to initialize the controller, set baud rates, send and receive frames, and handle interrupts. Example code and wiring diagrams are widely available in community repositories and documentation.

Common Applications

• Automotive diagnostics and CAN monitoring tools
• Vehicle communication and control modules
• Industrial automation networks and machine controllers
• Robotics systems requiring reliable multi-node communication
• Research and development labs for CAN protocol testing
