ncd-red-mcp3425 v1.0.4

This library provides a class for the MCP3425, it relies on the ncd-red-comm library for communication, and includes a node-red node for MCP3425. The MCP3425 is a 1-Channel Analog to Digital Converter with 16-Bit resolution, ideally suited for low-speed high-resolution sensor monitoring. Ncd.io manufactures a mini-module that utilizes this converter in an easy to use form factor. You can view and purchase the mini-module here.

Installation

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

npm install ncd-red-mcp3425

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 latest stable versions. If you skip this step the ncd-red-comm dependency may not load properly.
