The MicroView is the first chip-sized Arduino compatible that lets you see what your Arduino is thinking using a built-in OLED display.
You’ve never seen an Arduino™ compatible like this. With a built-in OLED (Organic Light Emitting Diode Display) you can see what your Arduino is thinking without having to connect it to your computer.
No more cryptic “Hello World” LED blink sequences or shoehorning oversized displays onto your tiny Arduino™. Development is much easier when you can see what’s going on.

Software simulator for Electronic Assembly display EA DOG series will bring you a clear image about possibilities of this favorite series.
Usually, when we start working with some monochromatic display with a color backlight, we have to imagine which combination of display/ backlight would suit us the best. It isn´t hard but for sure even here is valid, that “it´s better to see once than to hear three times”.
For this purpose will serve well a simple application StartDog, in which you can “try” for free various EA DOG series displays in combination with various color backlight (including RGB). This application will simplify you choice of a display without useless expenses. Besides a possibility to choice types themselves (with various resolution), it´s also possible to choose 4 basic kinds of “glasses”: STN positive Y/G, STN negative blue, FSTN positive and FSTN negative.
Application StartDog also cooperates with the EA9780-2USB development board and so the text or image displayed on your PC can be seen also on the EA DOG series display.
Detailed information will provide you the EA DOG flyer and the EA9780 user manual.
In case of interest in the EA9780 development board abd the EA DOG series displays, please contact us at email@example.com.

fowkc published his latest project the mains frequency display:
I wanted to make a display that could show the mains frequency to 3 decimal places. I’d be using the same seven-segment display modules that I used in my UNIX clock, so all I had to do was design the part that would work out the frequency.

Andrew Rossignol has written an article detailing his YALEDD – 16×16 LED display project:
The class was instructed to choose a simple circuit such as an LED flasher or a simple sequential state machine composed of discrete logic, capture the schematic, layout the PCB and have it made by the end of the term. I decided that it would be boring to design a simple state machine. I also thought it might be pretty cool to have an electronic gizmo of my own design to show off on my desk at work.

By Jim Harrison:
The human-machine interface, once simply known as an “operator panel” or “terminal”, is changing rapidly, due to the graphical, visual way operators now interact with an industrial machine or process. At one time, designers of these systems could get by with a three-line segmented LCD display. Today, LCD interfaces are quickly replacing traditional LED and segment LCD displays as designers take advantage of the aesthetic, flexibility, and cost benefits they provide.

Seven segment LED displays are known to be resource and power hungry. But because they are visually so charming and readable from a far viewing distance and at a much wider viewing angle as compared to any other electronic displays, they are still hugely popular. The required number of I/O pins to drive the LED segments can be reduced significantly by using an additional dedicated hardware. For example, the MAXIM’s MAX7219 device allows you to interface 8 pieces of seven segment LED modules using only 3 I/O pins of Arduino or any other microcontroller.

Visual TFT is a standalone application used for rapid development of graphical user interfaces for TFT displays. Software generates code compatible with mikroElektronika compilers: mikroC, mikroBasic and mikroPascal, for all suported MCU architectures: PIC, dsPIC30/33, PIC24, PIC32, AVR and ARM. Software implements intuitive environment and many drag-and-drop components which can be used for building applications easily and fast.

This (SPI7SEGDISP4.40-1R) is a revised version of the previous SPI seven segment LED display (4 digit) board that displayed numerals and decimal points. The new version has a better quality seven segment LED display (LTC-4727JS) with three extra LED segments, as shown below. The additional colon segments are useful in projects where you need to display time (HH:MM or MM:SS).

One of the basic usage of the TIMER peripheral on every microcontroller is to provide the accurate timing mechanism. Using the TIMER peripheral as the basic timing, we could easily develop a stopwatch and display it to the 8-Digit seven segment numeric LED display. Thanks to the Maxim MAX7219 chip which enable us to interface this 8-Digit seven segment LED display much easier using just three wires of the SPI (serial peripheral interface) to display the hour, minute, second, and hundredth of seconds to the 8-Digit seven segments LED display.
