Exclusive 1.38″ Round TFT LCD
The uLCD-220RD is a unique 1.38″ Round LCD Intelligent Display Module powered by the 4D Systems DIABLO16 Graphics Processor.
The uLCD-220RD is designed for applications such as gauges and instruments or for special applications such as robotics.
Driving the display and peripherals is the DIABLO16 processor, a very capable and powerful chip which enables stand-alone functionality, programmed using the 4D Systems Workshop 4 IDE Software. The Workshop IDE enables graphic solutions to be constructed rapidly and with ease due to its design being solely for 4D graphics processors.
The display module has an array of features including PWM, micro-SD memory storage, general purpose I/O including Analog Inputs, multiple TTL Serial, I2C and SPI channels, Quadrature Input, Pulse Output and multiple millisecond resolution timers, amongst many more features.
The uLCD-220RD features a 30 way 2.54mm pitch male pin header, where all of the IO available on the Diablo16 processor have been broken out for the User. It also features a 10 way 2.54mm pitch male pin header which is common to a majority of 4D Systems display modules, and is used for programming the module with our Workshop4 IDE, using a Programming Cable or Adaptor.
If you are after a unique display solution for your project, maybe an Automotive Gauge or Instrument Dial, or even a Robot Head, look no further than the 4D Systems uLCD-220RD Round TFT LCD Intelligent Display 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.
Designer
Visi
Visi-Genie
Serial
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:

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.
