86 participants saw the real demonstrations of fast 4D Systems displays programming live.

4D Systems displays are user-friendly so you don’t have to be an expert. You could learn more about them during SOS webinar, that was dedicated to 4D Systems displays. This webinar informed you about:

  • advantages of modules and 4D Systems displays,
  • development environment,
  • unique development process.

Developers appreciated practical demonstrations of programming because it is better to see once than to hear 100 times.  From among all participants who submitted short questionnaire, we have drawn a new owner of programming cable. ŠThe winner is Mr. Kamil Palčo from PALCO IT, s.r.o.

Congratulations to the winner. You already can register for next webinars which we prepare for you. More information about current webinars can be found at www.soselectronic.com/webinar.

You can watch the complete 4D systems presentation from the webinar online

Displays from 4D Systems can be used even if you don´t have experience with programming of graphic displays. Let´s look at how …

No doubt, that a graphic display significantly improves a user interface of practically every product. Maybe a little less obvious is the fact, that already a relatively small display with a touch panel is able to replace many buttons, switches, potentiometers and even a keyboard.  
Many designers are discouraged by a fact, that for a successful usage of graphic display, it is usually necessary to study a large documentation and it lasts a considerable time till a man reaches usable results. Then, mainly at smaller projects is the development too much time consuming, thus unprofitable.

Anyhow it may sound unbelievably, but  for a successful usage of 4D Systems graphic displays, it´s not necessary to know virtually anything about the given graphic processor, about commands, …
For many applications, it´s sufficient to use the VisiGenie graphic editor, which is a part of the  Workshop IDE software package (freeware). We already brought you a brief description of this editor in the article – Genially simple and fast programming of 4D Systems displays. The keystone of VisiGenie is, that literally within few minutes it enables to create menu with various buttons, potentiometers, switches, „7-segment displays“, various panel meters, pictures, video, sound, geometric shapes, …

The second basic feature of the program created in Visi Genie is, that many objects can be “binded” to each other through so called events – for example – by sliding a potentiometer, a value of a display or a panel meter can increase. At the same time it is possible to (very simply) define an event „report message“, when for example at switching on a switch (on a display), the uLCD module sends a message through a serial port. This message can then be used in a microcontroller of your device.   Output of the VisiGenie is a short service program, which will be loaded to EPROM of the graphic module and the main program with data, which will be saved to a uSD card (through a reader of your PC). Inserting a uSD card into the display module we get a fully operating display in such a way as we designed it in the Visi Genie.

Graphic interface, designed by this procedure, is able to send data through a serial port into your microcontroller and also many objects can be controlled by sending simple commands into the module. Neither these commands aren´t necessary to be searched in a documentation, because the 4D Workshop contains a tool GTX – Genie Test eXecutor, able to simulate and test functionality of the programu created in VisiGenie. A great advantage is, that the GTX tool directly shows commands responding to a given activity (for example if we want to set a panel meter to a certain value, or we want to read the displayed value). Note – as the GTX tool communicates directly with a display, it is operating only if a display is connected to a PC.
The best idea about this powerful graphic SW will provide you the attached video. 4D Worshop4 IDE and user guides are free to download from the 4D Systems website. Already now, we can promise you to publish a short presentation of the graphic program creation soon.

It has been 7 years (!) since I posted my PIC18F2550 KS0108 Graphical LCD Oscilloscope code and schematics. I have long since taken the circuit apart, sold my PIC microcontrollers, and moved on in my life (as one can surmise from my most recent posts detailing my graduate and postdoctoral work). However, I still get inquiries about the Microchip PIC oscilloscope, so I decided to recreate it using a simpler setup using my Arduino Fio.

A couple of weeks ago, I just post a review of my MCP23017 breakout board. As the board configuration allows to connect up to 8 of these boards, I decided to do it and see that it really works. My goal is interface 8 LCD displays with two wires: SDA and SCL from an I2C bus. With direct IO`s of a microcontroller, you need at least 48 lines to control all the displays. With this option (and a little of software, of course), you can do this with only two lines.

startingelectronics.com has a very clear tutotrial on how to read analog voltages using Arduino:

Analog channels A2 to A5 on an Arduino Uno are used to measure four different voltages. The measured voltages are displayed on a 16 character by 2 line LCD. The four channel Arduino multimeter can measure four independent DC voltages that can each be in the range of 0 to 50V. Voltages are displayed with one decimal place, e.g. 5.3V, 12.8V, etc.

www.4dsystems.com.au introduces a new solution for intergrating the PICASO processor on your design:

The PICASO-OGM lets you incorporate the full capabilities of the PICASO Graphics Processor and our TFT-LCD displays into your own custom design. The PICASO-OGM is ideal for high-volume applications that require a custom design.

Development with the PICASO-OGM is as easy as with our standard display modules. Simply choose your preferred display size, incorporate the PICASO-OGM into your hardware design, and use the 4D Workshop4 IDE to design your Graphical User Interface.

The OGM Module can be utilised to provide a display solution with 2.4″, 2.8″, 3.2″ and 3.2″ Wide 4D Displays. At a PCB size of only 34.8 x 34.8 x 4.3 mm, the module can easily be integrated into your designs.
The OGM Module breaks out all of the General Purpose I/O of the PICASO Processor.

Additionally, the module hosts an on-board micro-SD Card connector for storing images/videos/files used by the PICASO, and a 40-way FPC connector to connect to existing 4D Systems’ displays. All displays are also available for purchase separately.

Well-proven graphic displays Bolymin BG series represent a very suitable and cost-effective choice for applications, where we need not only character- but also graphic output. 

Series BG from company Bolymin belongs to a group of universal displays with an excellent price / performance ratio. Each type contains some of standard LCD controllers, that´s why it is relatively simple to control them.

Graphic displays naturally provide an advantage of possibility to display any characters and symbols. BG series displays are suitable mainly for applications, where a display serves as an informative interface for example with various values about the status of a measured parameter, including pictograms and other graphic symbols. As these displays don´t comprise powerful graphic processors, they feature a relatively very low power consumption. To a low power consumption also contributes the built-in LED backlight (white or color depending on a type).

Detailed information can be found in datasheets at particular types.  In case of interest in any Bolymin product, please contact us at info@soselectronic.com.

If you have used LCDs in projects before you have realized that to use the backlight on a LCD display you need large positive and negative voltages. This circuit will help you create the voltages you need from a simple 2.5V to 6V input. I chose this circuit since many of my projects run off of two AA batteries.  The one IC in this circuit, LT3587, generates two positive and one negative high voltage supply.

Here is the circuit.
