Programmable touchscreen display
The uLCD-32PTU-AR is an Arduino Display Module Pack, which includes a uLCD-32PTU 3.2" LCD Display with Resistive Touch, a 4D Arduino Adaptor Shield and 5 way interface cable.
The uLCD-32PTU-AR customises the uLCD Display specifically for interfacing with the Arduino, to provide a quick and easy interface without any wiring hassles. The Arduino Display Module Pack enables an Arduino user to quickly connect the 4D Arduino Adaptor Shield to their Arduino, connect the 5 way cable between the Adaptor and the Display Module, and be connected in seconds to start programming their new 4D Systems Display. The uLCD-32PTU-AR has a comprehensive range of serial commands ready to be received from the Arduino, to draw primitives such as lines, rectangles, circles and text, displaying images, playing sound and logging data to uSD card. It can utilise the Arduino's UART Serial Port and a single Digital pin.
Programming the touchscreen display
4D Systems provides a free Windows-compatible software environment for programming the touchscreen displays. Workshop4 includes four development environments, for the user to choose based on application requirements or user skill level. ViSi - Genie is an advanced environment that doesn't require any 4DGL coding at all, it is all done automatically for you. The software provides a toolbar filled with graphical widgets. These can be simply dragged to lay out the prototype interface with the objects you want, 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.
The 4D Workshop programming environment can be downloaded from:
[Latest News: Thanks to Max Danilin and Victor Nakoryakov (lead developers for XOD) - for a new XOD library for code-free programming of 4D Systems touchscreens. Grab a copy of the library for code-free programming of custom interfaces using your Biomaker Starter Kit, and provide feedback to the developers.]
ViSi-Genie is a drag-and-drop rapid development tool for designing and building graphic user interface on 4D Labs processor-based displays.It provides an easy method for designing complex graphics user interface (GUI) applications without any coding. A simple GUI application to be ‘designed’ from scratch in literally seconds. ViSi-Genie does all the background coding, with no 4DGL programming language to learn.
Pick and choose the relevant objects to place on a virtual display. The full animation of the objects will be done under-the-hood, such as pressing a button or moving the thumb of the slider. Each object has parameters which can be set, and configurable events to animate and drive other objects or communicate with an external host. Simply place an object on the screen, position and size it to suit, set the parameters such as colour, range, text, and finally select the event you wish the object to be associated with, it is that simple. Objects are classified in three different groups:
INPUT OBJECTS, as a button or a keyboard, OUTPUT OBJECTS, as a gauge or a meter, and COMBINED OBJECTS or INPUT/OUTPUT OBJECTS, as a slider which acts as both an input and an output.
In seconds you can transform a blank display into a fully animated GUI with moving meters, animated press and release buttons, and much more. The assembled code can be directly downloaded to a 4D Systems display to check the screen display. ViSi-Genie also provides debugging tools to poll communication streams to/from the programmed display. The ViSi-Genie environment runs under Windows, but can be well implemented under Mac OS X using an emulator like Parallels.

Below: (left) Examples of button/switch input widgets that can be added to a display, to create a custom user interface.
Using ViSi-Genie with an Arduino based display
Generally, the user will design a user interface in ViSi-Genie for the specific display model. The layout can be tweaked interactively in the development software. When finished, the interface code will be downloaded to the display controller via its serial port. GUI interface features can be tested by interacting with the display. ViSi-Genie also provides debugging features for serial communication. When ready, the programmed display can be connected to an Arduino board via serial ports.
4D Systems Application Note: Connecting a 4D display to an Arduino host
This application note shows how to create a ViSi Genie program and how to use the ViSi Genie library for the Arduino IDE. To achieve these objectives, a simple project is developed. This consists of a 4D Picaso module displaying six objects – a LED digits, a slider, a cool gauge, a string, a user LED, and a static text (label). To recreate the application described in this demo, the user first creates a ViSi Genie program in the 4D Workshop IDE and downloads it to a 4D display module. In this example, the Arduino host is programmed using the Arduino IDE. The Arduino and display communicate via a serial port. The Arduino programme loop must be configured to receive commands from interactive controls on the display, and to send relevant updates.
Arduino IDE software library:
4D Systems provides an Arduino IDE library that allows the use of programmed displays with Arduino boards programmed with the standard IDE.
This IDE library provides high level functions for the Arduino, to simplify communication with 4D Systems modules when using a module configured with ViSi-Genie. Inside the library are 3 example sketches, to assist with getting started using this library. Inside is also a ViSi-Genie Workshop4 project, which can be used on a range of 4D Systems displays (designed for a uLCD-32PTU). It illustrates how to use some of the commands in the library include Read Object, Write Object, Reported Messages, Write Contrast and Write String. There are well-documented examples available from 4D Systems.
4D Systems Application Notes:
Programming with XOD
One of the immediate tasks for the Biomaker community will be to adapt available Arduino code, and produce XOD nodes capable of code-free serial communication with the programmed touchscreen displays. We hope to start this with the 2018-2019 Winter Challenge. The task is made easier by limited number of user interface elements, and and conserved communication formats and addresses.
Process will be posted on this website.
