delcom-indicator

A node library to drive a Declom Visual Indicator

Our development roadmap is on the delcom-indicator Trello board

Install

npm install delcom-indicator

Use

var DelcomIndicator = require('delcom-indicator');

var delcomIndicator = new DelcomIndicator();
delcomIndicator.flashRed();
delcomIndicator.close();

A more complete example is found in tests/spike.cs. The test opens an attached Delcom light and runs through the available functionality by turning it solid greed, red and blue and then flashing each color.

Supported Platforms

This library is known to work on Mac and Linux platforms where node-hid can be installed. It was designed and tested on Mac OS/X 10.9.2, Max OS/X 10.11.3 and Raspian (all updates installed as of March 12, 2016). It has not been tested on Windows but should work provided that node-hid can be installed. It requires Node 4.x or higher.

Depending on your platform, Node-hid may require a compile, which adds additional dependencies. See the node-hid readme for details.

On Linux you need to grant permissions to write to the Delcom device. On Raspian, you can create a file:

sudo nano /etc/udev/rules.d/85-delcom.rules

With the following rule (replace the group name with a group of your choice):

SUBSYSTEM=="usb", ATTRS{idVendor}=="0fc5", ATTRS{idProduct}=="b080", ACTION=="add", SYMLINK+="delcom", MODE="0666", GROUP="[your group]"

You will have to reboot to make the rule take effect.

Development Prerequisites

You need to install gulp-cli globally using:

npm install gulp-cli -g

You can then run tests using:

gulp

The tests require you to have a Delcom USB device connected.
