2.83″ AMOLED Display

The 2.83″ AMOLED display is a very high quality, high viewing angle, crisp and clean viewing display that is suited to a large range 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 uOLED-32028-P1(T) is a clever combination of a 2.83″ (240×320) AMOLED Display, audio amplifier and speaker, micro-SD card connector, along with a group of general purpose input/output pins (GPIO’s), including I²C and serial COMMS.

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.

Designer

Enables user to write 4DGL code to program the display module.
4DGL syntax is similar to C: no need to learn a new language.
4DGL is optimized for GOLDELOX, PICASO, PIXXI and DIABLO Controllers.

Visi

Aptly named, a visual programming experience as you develop the display.
Enables drag and drop of objects in a WYSIWYG editor.
Software generates 4DGL code for the graphics.

Visi-Genie

An advanced environment; no 4DGL coding Required.
Everything is automated.
Drag and drop objects on the display.
Code written automatically.

Serial

ransforms the module into a serial slave.
Control the module from any host microcontroller with a serial port.
All serial protocols and documentation are provided.

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

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.
