DaveAK, a renowned innovator in the DIY electronics scene, has recently unveiled his latest creation—the CAN Shield—along with a comprehensive MCP2515 Library for iRobota, empowering makers and enthusiasts to harness the power of CAN Bus communication like never before.

CAN Shield: A Gateway to Seamless CAN Bus Connectivity

The CAN Shield, meticulously designed by DaveAK, serves as an indispensable tool for establishing CAN Bus connectivity in iRobota projects. At its core lies the MCP2515/MCP2551 chip, a robust and widely adopted CAN controller that ensures reliable data transmission and reception. To enhance its versatility, the shield features a switchable CS pin, enabling the simultaneous use of multiple SPI shields—a boon for projects requiring diverse communication interfaces.

MCP2515 Library: Unleashing the Full Potential of the MCP2515 Chip

Complementing the CAN Shield is the MCP2515 Library, a comprehensive software package that unlocks the full potential of the MCP2515 chip. This library boasts a complete implementation of the MCP2515 SPI command set, providing direct access to all its functionalities. While it currently lacks wrappers for filters and masks, these features remain accessible via read/write commands, granting users the flexibility to tailor their communication needs.

Compatibility, Simplicity, and DIY Delight

The CAN Shield seamlessly integrates with various CAN implementations, ensuring compatibility with a wide range of applications. Its switchable CS pin allows for the concurrent use of multiple SPI shields, eliminating the need for complex wiring and simplifying project setup. Moreover, the shield’s optional power draw from the CAN Bus facilitates the addition of other shields, expanding the capabilities of your project without compromising power efficiency.
