    NPM

    Flash application for MCP-CAN-Boot, a CAN bus bootloader for AVR microcontrollers attached to an MCP2515 CAN controller.

    The bootloader

    More information about the bootloader are available in the official repository: https://github.com/crycode-de/mcp-can-boot

    Requirements

    • Node.js version 12.x or higher.

    • The system where the flash-app is run needs a CAN interface to which the target MCU is connected.

      This may be a Raspberry Pi with an attached MCP2515 CAN controller, for example.

    Usage

    No need to install: Just run the flash-app using npx (this will take a moment):

    npx mcp-can-boot-flash-app [...]
    

    Or install it globally and run it if you need it more often (recommended):

    npm install -g mcp-can-boot-flash-app
    mcp-can-boot-flash-app [...]
