ADS7828
This library provides a class for the ADS7828, it relies on the ncd-red-comm library for communication, and includes a node-red node for the ADS7828. The ADS7828 is an 8-channel, 12-bit, I2C compatible, analog-to-digital converter. Ncd.io manufactures a full breakout board that utilizes this chip, you can find it here.
Installation
This library can be installed with npm with the following command:
npm install ncd-red-ads7828
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. The datasheet contains more information on specific settings. 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 LTS versions. If you skip this step the ncd-red-comm dependency may not load properly.
