Linux Driver for ENTTEC Open DMX USB dongle

Open DMX USB is an open USB to DMX dongle hardware design developed by Enttec. The Open in Open DMX USB refers to the fact that everybody is free to use the design and produce its own USB DMX Dongle without paying any licenses. Since this fits the Linux philosophy I wrote a small Linux 4.X kernel driver to make it possible to use the dongle under Linux. Getting the Driver The source code of the driver is now hosted as dmx_usb_module on GitHub. [Read More]


RGB LED Display test
