4.3″ Embedded SPI Display

The 4DLCD-FT843 is an embedded SPI display from 4D Systems, featuring a 4.3″ resistive touch display with an integrated FTDI FT800 Video Engine.

The 4DLCD-FT843 is a powerful SPI Display which enables a SPI host to be connected directly to the display, providing a powerful set of graphics features to the host using the on board FTDI FT800 Video Engine.

This display provides 4 in one functionality, a 4.3″ TFT LCD Display, Audio with amplifier enable, and Resistive Touch screen and an integrated Video Engine. This combination built directly into the screen allows for simple integration into a number of applications.

The FT800 Display Processor runs the FTDI version of EVE (Embedded Video Engine), which targets high quality graphics displays with Widget support, designed to offload the Host Processor and provide a variety of graphics features.

4D Systems has designed an Arduino Shield nicknamed ADAM (Arduino Display Adaptor Module) to interface with the EVE driven 4DLCD-FT843 Display, along with a simple breakout board (4DLCD-FT843-Breakout) to attach to a generic host or breadboard. Please refer to their product page on the 4D Systems website, and associated Documentation.

All software support for the 4DLCD-FT843 Display is provided directly from FTDI. FTDI also write and supply the libraries and demos for this shield/display combo. Hardware support is provided by 4D Systems.

WORKSHOP4 IDE

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.

DEVELOPMENT ENVIRONMENTS THAT SUITS ANY APPLICATION & USER LEVEL

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

WORKSHOP4 PRO

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

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

DOWNLOADS

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.
