New graphic display EA DIP180B-5NL brings a high contrast, small power consumption and a fast response. And what is important for the most of people – it is also available with a touch panel.
Display EA DIP180B-5NLWTP was designed for use in industrial control panels. That´s why it is available with an analogue resistive touch panel. This enables to combine control of a device and display of information into a single unit. EA DIP180B-5NLWTP is a graphic display with 180×32 pixels resolution. It contains 3 integrated graphic controllers SED1520 type (or compatible) used to control left, center and right sections of the display. White LED backlight provides crystal-clear picture and excellent readability under all light conditions.
Touch panel is linked to an external controller or a controller with analogue inputs. Touch panel operates similarly like a potentiometer – if a voltage is connected to the „Top-Bottom“ input of the controller, a voltage proportionate to Y (vertical) position is read by a microcontroller from the „Left-Right“ input. By the same process can be a horizontal – X position of a contact determined. Display provides a high level of contrast and a fast response thanks to the use of an LCD „supertwist“ technology. Even at extremely low temperatures of -20°C, the response time is a sufficient 2.5 sec. Module features an automatic temperature compensation, that´s why they don´t require any external contrast compensation during operation. Together with a wide specified temperature range from -20 to +70 °C, the display is ideal for various industrial applications. To fix the module mechanically, it is necessary only to solder pins directly to a PCB, without a need to use screws or other mechanical components.

Arup wrote a guest post about his Nokia LCD breakout board:
I designed a simple Nokia LCD Breakout board which allows you to interface any Nokia 6100 compatible display to microcontroller like PIC and AVR. The board itself provides 6.8volts for the backlight by a simple boost converter built up using a common 555 timer IC. There’s a switch to choose whether you want to work with 5V logic, or with 3.3V logic. [via]

Programming of a graphic interface perhaps cannot be any simpler. Company 4D Systems brings to developers a new powerful graphic editor, which further shifts borders of simplicity and speed at a creation of a graphic output.
4D ViSi tool enables to very easily and intuitively arrange graphic control and displaying elements into the layout which we wish to achieve on the 4D Systems display modules. As a result, this way you will create the graphic interface very quickly and you can fully focus on the main – the application itself. In other words – you can put your effort to what the application “has to do” and not “how it should look”.
4D ViSi tool is a part of the 4D Workshop3 IDE – Alpha program, which is free to download. 4D ViSi is a powerful SW tool, which enables an immediate overview of your desired graphic layout for 4D Systems display modules. 4D ViSi contains a set of various dials, gauges and meters, which can be simply dragged and dropped onto the desired place. Every item has wide possibilities of adjustment. Without necessity to always reload the source code to a display module, you have a possibility to see every change on a monitor of your computer and all relevant code is inserted into the program at one click. In the enclosed video you can gain a closer view of the work in this program.
Focus on application itself and the 4D ViSi will take care about its look - [Link]
These displays are small, only about 1″ diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128×32 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

In the first part of this tutorial, we discussed about Winstar’s WDG0151-TMI GLCD module, which is a 128×64 pixel monochromatic display built with KS0108B and KS0107B compatible display controllers. The module was interfaced to a PIC16F887 microcontroller and a test program was written in C to demonstrate how to implement the KS0108 instruction set in the firmware of PIC to activate display pixels on the screen. We wrote our subroutine programs that would turn the GLCD on, move the display location to a specified row and column, and draw a pixel at a given coordinates. You might have realized it by now that how much of effort is required to write the firmware for just plotting a point on a GLCD screen. Today’s discussion will focus more on using the built-in GLCD library routines of mikroC Pro for PIC compiler, which will make your life a lot easier if you are using a graphical LCD in your project.
The General purpose 16×2 or 16×1 char LCD are very easy to interface with any microcontroller , and these lcd are really very cheap and thoroughly available in the whole world, but the only problem with these lcd is they require 4 or 8 data lines + 2 or 3 control line to at minimum 6 line and maximum 11 lines are required. that not good because many small package microcontroller like PIC10 ,PIC12,PIC16 from microchip ,MSP430 Texas Instrument and Attiny from Atmel there all microcontroller have either 6 to 15 I/O lines. in this condition this technique will save you many I/O line because in this we use only 2 wires to connect the lcd with any microcontroller.

The use of a graphical LCD (GLCD) drastically changes the look of your project. It provides more freedom for presenting data than the HD44870 based character LCDs. Today we will see how to interface a KS0108 (name of the display controller chip) based GLCD to a PIC microcontroller. This experimental tutorial is divided into two parts. In the first part, we will see how to write a firmware for the PIC microcontroller to initialize the GLCD and send data to plot points and lines on the screen. The second part will focus more on exploring the built-in GLCD Library of mikroC Pro for PIC compiler to display more complex texts and objects. Since GLCDs are real resource hungry devices (in terms of required I/O pins and memory), a bigger size PIC microcontroller (PIC16F887, which has 36 I/O pins and 14KB flash memory) is selected for this experiment. I am using MikroElektronika’s UNI-DS6 development board to demonstrate this project, but the circuit setup can also be made on a breadboard.

This is a quick tutorial on getting a VFD working with an Arduino (or Arduino equivalent system). VFDs are beautiful devices with a wonderful hexagonal mesh of wires and this lovely green/blue glow. Operating at around 5V, they offer a nice alternative to high voltage Nixie tubes, while still retaining a lot of the charm.
This tutorial will show you how to connect a Arduino-like device to a VFD display as well as a basic program to display text.

DOG series will start with 3 types: 1×8 character, 2×16 and 3×16 character. Outline dimensions are very compact with 55x27mm and especially designed for handheld applications and low power applications. Thanks to the most modern Chip-On-Glas technology (STN and FSTN) overall height is 2.0mm only. Even together with LED backlight thickness will increase to 5.8mm only. Operating temperature range of –20..+70°C (temperature compensated) is standard.
Standard character height of 5.57 mm for the 2×16 makes „DOG modules“ easy readable. User can decide for 3 different interface 4-Bit, 8-Bit and SPI. No need to say that character set with full 248 ASCII characters is installed. Because of direct placement onto pcb production and mounting cost are unequaled low. No special mounting is required.
Combining various display technologies (positive/negative, blue/green/black) with different backlights (white, blue, amber, yellow/green, red) gives the advantage of many different design looks.

Graphic solutions from 4D Systems are the proof, that a powerful graphic interface doesn´t have to mean big expenses and a long development time. So, give your applications the 4-th dimension!
Australian company 4D Systems, whose products we added into our offer, specialises in graphic solutions, which are very user-friendly and require a relatively small developing effort in order to reach very decent results.
Basis of 4D Systems graphic solutions represent two powerful chips – Goldelox and Picaso. Chips contain graphic processor, memory and interface for common LCD and OLED displays, and – depending on the type – also a support for a touch panel. Graphic chips and modules with these chips represent a powerful and user friendly platform for creation of graphic interface to a wide range of devices.
A common feature of both chips is, that they can be reconfigured into a slave graphic chip mode with a serial interface – SGC (slave graphics controller) – – for a work with the host microcontroller, or into a stand-alone graphic processor mode – GFX (stand alone host graphics controller). It is possible to change these chip features anytime by a simple reloading of free configuration file.
Goldelox – is a low cost chip supporting a powerful graphics, text, pictures, animations, macros and other. It can be used with a simple serial interface for a work with a microcontroller (SGC version) or as a stand-alone graphic processor (GFX version). It can work with many usual series „80“ LCD and OLED displays, with 8 bit interface. Chip can generate a sound, supports SD cards through SPI interface and many other. Read the rest of this entry »
