DevoVision license information

This license overview details what third party software and services the DevoVision software utilizes.

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 proprietary 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 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:
