3.5" Intelligent Display Module Pack for the Raspberry Pi A, B and B+
This 4D Systems Display Module Pack for the Arduino (and variants) is made up of a uLCD-35DT 3.5" TFT LCD Display Module with Resistive Touch and a 4D Serial Pi Adaptor and 5 way interface cable, for quick and easy connection to a Raspberry Pi.
This Display Module Pack enables an Arduino user to quickly connect the 4D Serial Pi Adaptor to their Raspberry Pi, connect the 5 way cable between the Adaptor and the Display Module, and be connected in seconds to start programming their new 4D Systems Display.
The uLCD-35DT can be configured in a number of ways using the 4D Systems Workshop4 IDE. There are 4 programming Environments to choose from, to enable the widest range of options possible and to suit a wide range of Users and projects alike.
The uLCD-35DT-PI has a comprehensive ViSi-Genie library written to communicate with the Raspberry Pi, allowing the Visi-Genie events to be easily understood by the Raspberry Pi and users code.
Utilises the Raspberry Pi's UART Serial Port.
For a detailed listing of the capabilities of the display module in this Raspberry Pi Pack, please refer to the datasheet for the display itself, available from the Product Page of the uLCD-35DT.

Getting Started Manual available as a Download
If you are a first time user and just beginning your development, we strongly recommend purchasing a Starter Kit of this same model as it includes additional items that allow you to get started with your development immediately.
Starter Kit part number is SK-gen4-35DT-Pi.
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.
This environment enables the user to write 4DGL code in its natural form to program the display module.
ViSi - Genie
An advanced environment that does not require any 4DGL coding at all. Everything is done automatically for you. Simply lay the display out with the objects you want (similar to ViSi), set the events to drive them and the code is written for you automatically. ViSi-Genie provides the latest rapid development experience from 4D Systems.
A visual programming experience that enables drag-and-drop type placement of objects to assist with 4DGL code generation and allows the user to visualise how the display will look while being developed.
This environment is also provided to transform the display module into a slave serial display module. It allows the user to control the display from any host microcontroller or device with a serial port.
SMART WIDGETS EDITOR
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
- Quarter-Rotary Menu
- Dock Menu
- Fading Slide-To-Unlock Button
- Spectrum With Transparency
- And Many Others
