description Add general purpose input/output lines to your computer based projects. This circuit is a 12 pin digital GPIO interface using the Microchip PIC18f14k50 microcontroller which connects to an USB host port. The microcontroller is available in through-hole DIP20 and SMD packages, too. Circuit diagram The device is powered by the USB bus. 12 port […]

Using adaptive current-limit PFM (pulse frequency modulation) control, the ISL9120 switching regulator from Intersil realizes efficiencies of up to 98%, while automatically transitioning between buck and boost modes without significant output disturbance. The part accommodates a wide input voltage range of 1.8 V to 5.5 V and has an adjustable output voltage range of 1 […]

Wireless technology IQRF was introduced to you in our recent article „IQRF – a wireless technology which breaks barriers“ and in our SOS webinar „How to integrate wireless technologies into your devices without a long-term programming?”. In the time of publishing of the previous article, was the IQRF Alliance launch in a status of intensive […]

First of all, if you have any questions, feel free to comment! I’d be more than happy to answer your question as good as possible!! Materials used : – PIC 18F452 Microcontroller ( any PIC microcontroller with enough pins will do ) – 7 Segment common anode LED display – 24 Mhz Crystal – A […]

With Eltechs ExaGear Desktop you can run Intel x86 application on your ARM-based Mini PC simultaneously with common native applications. ExaGear is a virtual machine that implements virtual x86 Linux container on ARM and allows you to run Intel x86 applications directly on ARM. It is like QEMU but 5 times faster! You can even run Windows […]

At this week’s IEDM 2014, held in San Francisco, California, nanoelectronics research center imec demonstrated an ultra-low power RFID transponder chip. Operating at sub 1V voltage and realized in thin-film transistor technology (TFTs) on plastic film, the chip paves the way for universal sensing applications, such as item level RFID tagging, body area networks (BAN) […]

jump to a section:supplies about LED arrays design construction customizing/programming washing and wearing troubleshooting and FAQ **NOTE** As of Fall 2007, skip the ugly microcontroller programming (don’t buy the STK500 or the AVR chip)… Get a LilyPad Arduino instead. It’s much easier to sew and to program! See my LilyPad Arduino tutorial for help on […]

An eight pin Microchip PIC microcontroller is programmed to operate from a 32768 Hz watch crystal and output waveforms which, when displayed on an oscilloscope, show the time in HH:MM:SS format. The screen capture shows winscope showing 12:46: … Step 1: Design the character set On an oscilloscope screen, vertical axis (up and down) corresponds […]

Researchers from the University of Bristol and NTT in Japan have developed an optical chip that can process photons in an infinite number of ways. According to the team, the fully reprogrammable chip marks a ‘new era of research’ for scientists and engineers at the cutting edge of quantum technologies. Dr Anthony Laing, who led […]
