9.0″ Intelligent Display Module with DIABLO16 Graphics Controller with Hardware Interface for Arduino
This 9.0” Diablo16 Integrated Display Module is part of the microLCD range of modules Designed and Manufactured by 4D Systems.
This hardware bundle includes the 4Duino Adaptor Shield II which allows fast and easy hardware inteface to virtually any Arduino Board with the standard Arduino Headers and allows you to quickly and easily add a full colour HMI to your Arduino project.
The 9.0” model was designed specifically to cater for the demand of physically large displays, for ease of integration and use, and with careful consideration for space requirements and functionality.
This specific module features a 9.0” colour TFT LCD display, with Resistive Touch (DT), or Capacitive Touch (DCT). It is powered by the feature-rich 4D Systems Diablo16 Graphics Processor, which offers an array of functionality and options for any Designer / Integrator / User.
The Diablo16 processor features include 16 customisable GPIO, capable of PWM, Serial, I2C, SPI, Pulse Out, Quadrature Input, and Analog Input.
The 9.0” Diablo16 Integrated Display Module features a TFT LCD Display, is capable of Touch Detection, microSD memory Storage, GPIO and Communications, along with multiple millisecond resolution timers, and Audio Generation.
This 9.0” module is 100% compatible with the Workshop4 IDE and its 4 different development environments, providing the User with a wealth of options for programming and controlling their system.
Anything designed to run on other 4D Systems display modules featuring Picaso or Diablo16 Graphic Processors can be run on this Integrated Display Module, with little or no required modifications. Please contact 4D Systems Support Team for assistance if migrating from a previous model.
This module features a 30 pin ZIF socket, designed for a 30 pin FPC cable, for easy and simple connection to an application or mother board, or for connecting to accessory boards for a range of functionality advancements.
The uLCD-90DT/DCT utilises the same PCB found on the popular gen4 Series Intelligent Display Modules, such as the gen4-uLCD-70DT, making integration and application sharing easy. Unlike the gen4 modules, the uLCD-90 range does not feature plastic frames with mounting tabs, and instead integrates metal mounting ears directly into the display housing.

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:
