MicroVGA (uVGA-III)
The uVGA-III is a compact and cost effective VGA Graphics Engine 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 module combines a display driver capable of 320×240 (QVGA), 640×480 (VGA) and 800×480 (WVGA) resolution output to a standard VGA display, micro-SD card connector, along with a group of general purpose input/output pins (GPIO’s), including I2C and serial UART communications.
This module serves as a perfect solution to connect to an external VGA monitor for an application requiring animation, slideshows, images or sound. This PICASO driven Intelligent Display Module is a perfect example of where art meets technology.
Audio support provided on the display module is supplied by the PICASO processor, outputting a line-level audio signal, ready to drive an external amplifier of choice. A simple instruction enables the user to play audio files while continuing the execution of the user application code, such as display updates, communications and much more.
The micro-SD card slot provides the user with expandable memory space suitable for multimedia file retrieval, including images, animations and movie clips, as well as data logging applications.
The module can be programmed as a master or slave device using the Workshop 4 IDE Software, but can also be configured as a serial slave for use with your favourite Host Controller. Freedom is at your fingertips with the intelligent uVGA-III VGA Graphics Engine module.

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.
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:
