A node library to drive a Delcom Visual Indicator
Our development roadmap is on the delcom-indicator Trello board
npm install delcom-indicator
var DelcomIndicator = require('delcom-indicator');
var delcomIndicator = new DelcomIndicator();
delcomIndicator.flashRed();
delcomIndicator.close();
More complete examples are found in the tests/*.js files. The light test opens an attached Delcom light and runs through the available functionality by turning it solid green, red and blue/yellow and then flashing each color. The buzzer test exercises the built in buzzer (if present) by playing some repeating sounds, and uses the BuzzerControl helper to play some tunes.
A Build Light indicator for TeamCity that utilizes this library to show the status of builds.
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 also been tested on Windows 10. 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.rulesWith 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.
You need to install gulp-cli globally using:
npm install gulp-cli -gYou can then run tests using:
gulpThe tests require you to have a Delcom USB device connected.
To run only the light or buzzer tests you can use these commands:
gulp light
gulp buzzer
