4.3″ Gen4 Primary Display for the Raspberry Pi – Capacitive Touch

The gen4-4DPi range are Primary Display’s for the Raspberry Pi A+, B+, Pi2, Pi3, Pi3 B+, Pi4, Pi Zero and Pi Zero W, which display the primary output of the Raspberry Pi, like what is normally sent to the HDMI or Composite output. It features an integrated Resistive Touch panel or Capacitive Touch panel, enabling the gen4-4DPi to function with the Raspberry Pi without the need for a mouse.

Communication between the gen4-4DPi and the Raspberry Pi is interfaced with a high speed 48Mhz SPI connection, which utilises an on-board processor for direct command interpretation and SPI communication compression, and features a customised DMA enabled kernel. This combination allows this display to output high frame rate compared to other SPI display solutions, when displaying a typical image/video, and can achieve higher depending if the image can be compressed.

The gen4-4DPi is designed to work with the Raspbian Operating System running on the Raspberry Pi, as that is the official Raspberry Pi operating system. It is also compatible with Pixel and Scratch.

The gen4-4DPi range connects to the Raspberry Pi’s 40 pin header using the gen4-4DPi Adaptor, which then connects to the gen4-4DPi display module using a 30-way FFC Cable.

Mounting of the gen4-4DPi is achieved with the 4x 4mm mounting holes present on the Resistive Touch Display Modules, enabling standard screws to fasten the Gen4-4DPi as required, or via the adhesive supplied on the Cover Lens Bezel which is part of the Capacitive Touch version.

Workshop4 is a comprehensive software IDE for Microsoft Windows that provides an integrated software development platform for all of the 4D family of processors and modules. The IDE combines the Editor, Compiler, Linker and Downloader to develop complete 4DGL application code.

All user application code is developed within the Workshop4 IDE.


Workshop4 includes four development environments for the user to choose based on application requirements or even user skill level.


Make complex widget design, simple.

Smart Widgets Editor is a powerful utility which enables the generation of Smart Widgets.

  • Users can create complex widgets with up to six layers, including the layer for the base image. The order of the layers can be arranged as desired.
  • Each layer can contain one or more images arranged in sequence that can be manipulated in a variety of ways. Image manipulation options include horizontal motion, vertical motion, and angular motion. Additionally, the transparency of a layer can be set.
  • Two or more layers can be linked to produce synchronized movements of images. This enables the generation of complex widgets with multiple moving parts. Clockwork feature is also supported. This enables users to quickly generate clock widgets.
  • Each layer can have a numeric part which can display numbers in various fonts and formats. Alternatively, the numeric part can be a fixed sequence of text.
  • The output frames can be utilized using any of the supported Workshop4 environments.


Genie Magic is an extension to ViSi-Genie, which is available in Workshop4 PRO. Genie Magic allows the User to add 4DGL code to various points in the ViSi-Genie backend code, which allows Users to take full advantage of the power of 4DGL, while retaining the speed and convenience of ViSi-Genie and its defined communication protocol.

Genie Magic allows you to enter 4DGL code in the form of Events, Code and Objects, along with various touch related additions too, giving you to the power to achieve advanced GUI’s in ViSi-Genie without having to write the full code yourself.

Genie Magic is fully supported by the genieArduino and geniePi libraries, making communication with an Arduino or Raspberry Pi host even more powerful.

When using Genie Magic in combination with the Smart Widget Editor, it is possible to use the Smart Widgets Editor tool and Smart Widgets to create other graphical user interface elements such as:

  • Dropdown Menu

  • Side Menu

  • ‘Carousel Slider’

  • List Box

  • Dock Menu
  • Quarter-Rotary Menu

  • Fading Slide-To-Unlock Button

  • Spectrum With Transparency

  • And Many Others


Compatibility: Workshop4 is a Windows-only product. It is compatible with Windows 8 through to Windows 11.

Note some older OS such as ME, Vista, XP and 7 have not been tested for some time and are not supported by Microsoft anymore; however, they may still work.
Legacy support updates for the older OS may not be possible, depending on what issues are found. For best results, run a current Windows OS. It is possible to run Workshop4 under a VM on Linux or Mac. However, it is up to the User to set this up.
