This library provides a class for the PCA9685, it relies on the ncd-red-comm library for communication, and includes a node-red node for PCA9685.

Installation

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

npm install ncd-red-pca9685

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.
