2.8" Intelligent TFT-LCD Module with Picaso Graphics Controller
The uLCD-28PTU is a compact and cost effective Intelligent Display Module packed with plenty of features, ready to become the GUI for your target application, and capable of being an interface controller for a number of applications.
Embedded at the heart of the design is the PICASO processor, which is driven by a highly optimised virtual core engine called EVE (Extensible Virtual Engine). An extensive range of hardware and software peripherals have been integrated into the design, to give the user freedom to adapt the module to suit almost any application.
The uLCD-28PTU is an elegant combination of a 2.8" (240x320) LCD Screen, audio amplifier and speaker, micro-SD card connector, Lithium Battery Support, along with a group of general purpose input/output pins (GPIO's), including I2C and serial COMMS.
The uLCD-28PTU display module serves as a perfect solution to be deployed at the forefront of any product design, requiring a brilliance of colour, animation or images on any application. This PICASO driven Intelligent Display Module is a perfect example of where art meets technology.

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-28PTU.
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
