    ncd-red-mcp23008

    1.5.5 • Public • Published

    This library provides a class for the MCP23008, it relies on the ncd-red-comm library for communication, and includes a node-red node for the MCP23008. The MCP23008 is an Integrated port expander that controls eight I/O channels through the I2C bus. Ncd.io manufactures dozens of boards, both mini-modules and full size, that utilize this chip for different applications. You can see a list here.

    Installation

    This library can be installed with npm with the following command:

    npm install ncd-red-mcp23008
    

    For use in node-red, use the same command, but inside of your node-red directory (usually ~./node-red).

    Usage

    The test.js file included in this library contains basic examples for use. All of the available configurations are available in the node-red node through the UI.

    Raspberry Pi Notes

    If you intend to use this on the Raspberry Pi, you must ensure that:

    1. I2C is enabled (there are plenty of tutorials on this that differ based on the Pi version.)
    2. Node, NPM, and Node-red should be updated to the LTS versions. If you skip this step the ncd-red-comm dependency may not load properly.

    Install

    npm i ncd-red-mcp23008
