GLight

Groovy based build light controller. In true minimalist fashion this script only works with

• Delcom 904006 Build Light (G2)
• Jenkins
• Ubuntu 14.04.

Please fork and adapt if you find it useful.

Prerequisites

Debian/Ubuntu

Create a file called /etc/udev/rules.d/85-delcom.rules containing the following

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

Replace "dalts" with your own user group. Now reboot to make sure it takes effect. This will give you write access this device on the USB port.

Depending on what version of Ubuntu you are running you may need the hidapi library - I found on my 14.04 box it worked fine, my 13.10 box that was upgraded to 14.04 needed it though.

    sudo apt-get install libhidapi

Everything else is handled by jni wrappers in javahidapi.

Mac OSX

Common Problems

Exception in thread "main" com.codeminders.hidapi.HIDDeviceNotFoundException

Make sure you install the HID library installed. Did you actually plug it in?

Exception in thread "main" java.lang.NullPointerException: Cannot invoke method sendFeatureReport() on null object

Did you add the udev rule?

Thanks to the following

• https://code.google.com/p/javahidapi - great little wrapper for the hid libraries
• https://github.com/cibuddy/cibuddy - works beautifully but is so heavyweight for what I needed and is OSGI (yuk - sorry OSGI lovers). The code was useful to work out the codes though!
• Andrew Purcell for loaning me the Delcom light to play with
