V-Control 4.0 Beta for ARM 32 / Raspberry Pi released

Today the promised Raspberry Pi version of V-Control is available for download. Please keep in mind that the power of a Raspberry is much less then a core i CPU.

The main application for V-Control for ARM should be small projects that require a low-cost platform and small form factor.

We also released the first Beta of V-Control 4.0 64 Bit for Linux. It was tested with Ubuntu 17.10 and Linux Mint 18.3, but should run on all distros with GTK3 support.

We are still looking for volunteers that help us testing the MAC OSX version. At the moment we assume that there is not much interest in a MAC OSX version, because nobody want’s to help us yet.

V-Control 4.0 Beta for Windows released

Today we released our brand new V-Control 4. The first release has beta status and is available for Windows 64 Bit only. Other platforms will follow, including Raspberry Pi.

New in V-Control 4

  • We implemented the concept of device variables. A device variable represents the status of a device, for example the time code position or power status. If one of those variables changes, an event is triggered. This event can handled by a task.  To request status messages from connected devices, the V-Control device driver send commands periodically and ask for status changes. This can be up to every 20 Millisecond. The answer is automatically processed and stored in the device variables.
  • Now two or more tasks can access the same device. V-Control buffers all commands and fires them if the device is free. This was necessary because of our new GUI designer and the concept how it works.
  • New Platform Raspberry Pi. V-Control 4 is prepared to run on Raspberry Pi. We’re really looking forward to the beginning of next year when we launch V-Control on this exiting platform.
  • Saving Projects is now processed by a separate Task, allowing to work during saving.
  • Save Increment saves Projects and automatically adds an incrementing number. So saving “MyProject.vc4” leads to “MyProject_001.vc4” saving that again leads to “MyProject_002.vc4” and so on.

Super simple and Cheap Android Touch Interface Part 1

As some of you might know there is a build in web server in V-Control that lets one create graphical user interfaces for V-Control. But to do this, HTML and JavaScript knowledge is necessary. In this article, I will describe a simple solution using an Android device, a cheap Bluetooth serial port and a V-IO interface. The V-IO is not really necessary, a simple Arduino Uno is sufficient, but with V-IO we also have a housing for the Arduino. Read more

Touch GUIs with WebSockets

One of the new features of V-Control 3.7.14 is the ability of the build in web server to handle WebSockets. This allows us to establish a stable, bidirectional connection between a web application and V-Control. The benefit of a bidirectional connection is, that our web application does not have to poll the V-Control web server to get status changes. As far as a status change of a device occurs, the information is sent to the web application. All we need is to write a handler for this status message and show the new status in our GUI.
