This library provides a class for the MCP3428, it relies on the ncd-red-comm library for communication, and includes a node-red node for MCP3428. The MCP3428 is a 4-Channel Analog to Digital Converter with 16-Bit resolution, ideally suited for low-speed high-resolution sensor monitoring. Ncd.io manufactures a multiple easy to use form factors that utilize this converter. You can view list of available boards here.
Installation
This library can be installed with npm with the following command:
npm install ncd-red-MCP3428
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:
- I2C is enabled (there are plenty of tutorials on this that differ based on the Pi version.)
- 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.
