microPython_MCP2515
A MicroPython library for interfacing with the MCP2515 CAN bus controller chip.
Overview
microPython_MCP2515 is a MicroPython library that provides an interface to the MCP2515 CAN bus controller, enabling MicroPython-based devices to communicate over Controller Area Network (CAN) protocols. This library is essential for embedded systems projects requiring reliable, real-time serial communication in automotive, industrial automation, and robotics applications.
Key Features
- MCP2515 Integration — Full support for the MCP2515 standalone CAN controller with SPI interface
- CAN Protocol Implementation — Handles standard CAN frames (11-bit IDs) and extended frames (29-bit IDs)
- Hardware Abstraction — Provides a clean API to configure baud rates, masks, filters, and transmission modes
- Error Handling — Includes functions to check error states and controller status flags
- Lightweight Design — Optimized for resource-constrained MicroPython environments
Philosophy
The library focuses on simplicity and reliability, offering a straightforward way to add robust CAN bus capabilities to MicroPython projects without unnecessary complexity.
