The touch screen technology is widely used in PDA, smart phone, PMP, ATM, information kiosk and many other types of equipment in industrial, medical and commercial environment. Actually the technology enabling these devices is not new, since it was invented by Dr. Samuel C. Hurst in 1971. But it becomes hotter after the release of popular iPhone and iPod touch. With new patents filed for the touch screen technology, Apple brings a new wave to this mature segment and more companies are involved in this revolution with improved interactive UI, ICs, assembly modules and software components.

The Scripting languages are deployed in many operative systems, either in UNIX/Linux or Windows. These languages are developed for general purpose process automation and web programming. But you can consider using them for the software development process in many ways. Among these languages, awk and Perl are suitable for automate and speed up software development for embedded systems, because many embedded systems only have cross tool chain, without powerful IDE supports for process automation.

I never handled an iPod touch until a few days a ago. But a friend of mine received as birthday present the media player iPod Touch and so I had the chance to analyze it. What can I say? It's very thin and surprising. Once you start using it, you can not leave it! The iPod touch has a reduced size: height 110mm, width 61.8mm and only 8 mm thick. Weighs only 120 grams. The 3.5 inches widescreen format display has a resolution of 480 x 320 pixels at 163 ppi. The iPod touch provides Wi-Fi wireless connectivity (802.11b/g) - the only iPod to have it. It is also provided with the lithium ion integrated battery that guarantees up to 24 hours of music and up to 5 hours of viewing video and web browsing. It can be charged through USB connection. With the iPod Touch you can listen to music, play movies and it can also be used to wirelessly surf the Web. All that really lacks is the ability to call another person.

Makefile actually is an old concept from UNIX development. Makefile is based upon compiling rules for a project and improve the project development efficiency. In a big project, there are many files in different folders. Of course you can write a DOS batch file to build whole project. But makefile can judge which steps should be done first, which steps can be ignored, and even more complicated goals. All of these are decided by the rules in makefile, instead of manually specified.

The idea was born from the knowledge that everyone of us has in the drawer at least one old GSM phone, that, for varied reasons, we do not use! The following application is realized using a PIC microcontroller connected to Ericsson T18 phones, testing the compatibility also with A1018 and T28. But it is not commercialized for reasons of difficult availability of the connectors, instead it can be a lot interesting for hobby use.

For those of you lucky enough to have attended CeBIT2008 this past March in Hanover, you might have seen another series of GPS devices debut: the next two additions to the GPS lineup for Navigon Max series: 2100 and 2120.

Today, the boundaries between the general purpose PCs, the servers and the embedded systems are more blurred. These computers are sharing same platforms, same peripherals. For example, an x86/Mac PC can be used as a server, an x86/PowerPC CPU can be used in an embedded system like portable navigation device (PND). On the other way, the popular embedded processor StrongARM was a powerful desktop PC processor for the DEC workstation, and the embedded systems often also act servers, like NAS (Network Attached Storage). As same as the hardware suppliers, the OS suppliers port their products into the desktop PCs, servers and embedded systems.

Ever since the beginning of the microelectronics era there has been an eternal quest to reduce the characteristic features on the devices: some devices are now in qualification states on the sub 40nm gate oxide range for an scheduled commercial release towards the end of the year, and there are a lot of efforts in the sub 30nm range.

Cypress is a very interesting company that has two important products: CapSense and PsoC. The staff knows this well, as well as the competitors: Quantum , IDT and Synaptics regarding CapSense capacitive sensors. Microchip , Atmel and Freescale regarding the micro, to whom Cypress replies with PSoC. Besides in the video you will also see the SuperSync Cypress memories performances compared to the Samsung ones...

Driving the power LED depends on the application setting and it is not so trivial as it might appear. The LEDs (Light Emitting Diode) are diodes whose basic characteristic is the ability to emit light when they are passed through a current that flows from P to N region. At each recombination between the charge carriers (electrons and holes), on PN junction region, a photo emission is generated, and the total quantity of emitted photons, and therefore the light intensity, is proportional to the current intensity that passes through them. The emitted light has a spectrum – wavelengths distribution – that is defined according to the materials used in the realization of the diode PN junction, although it partially depends on the current intensity and on the junction temperature.

This is the simplest topology and can directly replace the linear regulators previously described. The control circuit drives a transistor alternately in conduction status and interdiction status. During the conduction status the current flows from VIN to the diode (green dotted line on Fig. 5) and the energy initially associated to delta between VIN and the voltage fall on the LED, on the transistor and on RS is stored in the inductance. At the increasing of the stored energy in the magnetic circuit, the resistance decreases to the passage of the current, current that grows until the controller, that measures it on RS, does not drive the transistor to the interdiction status.

The LED using, in lighting applications, is becoming more and more attractive and the possibility of using the powerline directly, as a source of power supply, is becoming more and more interesting. Moreover, if the circuital solution allows a compact implementation that can be placed in the same volume of a standard lamp screw, it becomes more interesting.

It's the fad of the moment and, we, as designers, do love these Gadgets! But what they are? Are Development Tools in USB Stick format simply toys or are they offering a complete and reliable debug system? Surely the latter, because the capability (some of them have an ARM on board) and the versatility make a quality product highly useful for the developers. Some time ago I had the opportunity to "test" the Texas Instruments' Stick USB, the Ez430, related to the MSP430 Low Power Microcontroller, and I have to say that this "Gadget" (please note the quotes) surprised me, for its capabilities and easy of use. After 10 minutes I was already in step_by_step debug with my first application on Stick! (Ok, I did flashed a LED under interrupt while I had controlled the inputs in polling with debounce software, but the start-up times were reduced to a few minutes!!! )

Tools and information to simplify designing products based on power LEDs. In the myriad of parameters and curves that characterise the performance of a LED, it is necessary to define the set points from which the other major features can be gleaned, to obtain the final result: the real efficiency and reliability of our application.

In today’s competitive electronics industry, getting to market ahead of the competition can mean the difference between a successful product and one that misses its market window. Design cycle time plays a big part in determining a product launch schedule and the PCB layout portion of this process often is called upon to make up for early design phase schedule slips. One designer and one computer at a time can be a limiting factor.

The Ministry Information Industry (MII) of China enforced all mobile phone manufacturers to comply with new issued standard for phone charger interface, which is called YD/T 1591-2006 mobile phone charger and interface requirement and testing method. Before launching this standard, every mobile phone manufacturer has own power adapter interface with different electrical and physical specifications. Due to business and technical reasons, some vendors even offer different power adapters for same brand!
