Software license information

This page gathers license information about the various software made available by 3devo B.V. Select your software below.

DevoVision

DevoVision License Information

The core of the DevoVision software is copyrighted by 3devo B.V. and the software as a whole is licensed under a propietary end-user license agreement (EULA), which is shown to the user when the application is first opened.

However, the software consists of multiple parts and includes various third-party libraries, which are licensed under different terms. This document provides more information about all the different licenses that apply.

The DevoVision software roughly consists of two pieces: The connector program that runs on a computer and manages access to the hardware, and the frontend that runs in a browser and forms the actual application interface. These two components are bundled together to form DevoVision, but are considered separate programs governed under different licenses.

DvConnector

DvConnector is based on the Chilipeppr serial-port-json-server project, which is licensed under the GPL license. Hence the connector binary as well as the sources, are licensed under the GPL as well. Note that the original project does not clearly specify the GPL versions that can be used, but it includes version 2 of the GPL, so DvConnector is licensed under GPL v2-only to be sure. In particular, the following terms apply to the whole:

Copyright (C) John Lauer and various contributors Copyright (C) 2018-2019 3devo B.V. (https://www.3devo.com)

You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

The full license text and the source code for DvConnector can be found online at https://github.com/3devo/DvConnector or can be requested via e-mail to service@3devo.com.

DvConnector libraries

The compiled version of DvConnector bundled with DevoVision includes various third-party libraries under various licenses. A listing of these will be added here later. Until then, see the DvConnector sources for more info.

DvFrontend

DvFrontend is based on the Vue Admin Panel Framework project, which is licensed under the MIT license as shown below. The resulting work (DvFrontend) is licensed under the license stated in the DevoVision EULA.

The Vue Admin Panel Framework is licensed under the following terms:
