Near Field Communication (NFC) Introduction and Software Development

Android 2.3 features near field communication (NFC) in order to allow payment through your phone as it is already implemented in Japan with FeliCa (Felicity Card), a contactless RFID smart card system from Sony, direct communication between NFC devices, RFID reader, etc… NFC is already supported in Samsung / Google Nexus S. In this blog post, we’ll see what near field communication is, which hardware is needed and what needs to be done at the software level (driver and NFC stack). What is Near Field Communication ? Extract from Wikipedia: Near Field Communication or NFC, is a short-range high frequency wireless communication technology which enables the exchange of data between devices over about a 10 centimeter (around 4 inches) distance. The technology is a simple extension of the ISO/IEC 14443 proximity-card standard (proximity card, RFID) that combines the interface of a smartcard and a reader into a single device. An NFC […]

Android Remote Control App for Google TV

Google has just released a new app in Android Marketplace to be able to control your Google TV compatible set-top box or TV with your Android Smartphone. It just looks like a normal remote control, but you’ll also be able to use voice recognition to select your channel and videos, select a video on your phone to be played on the TV, etc… I wonder if this will engender family or friend’s wars since several Android phones can be used with one TV. Oh.. and also Google is offering 100 46″ Sony Google TV to the best videos. Deadline for submissions 22-12-2010, so it will end later today. Anyway, have a look at Google TV Remote App video below: Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time […]

HTTP Server for uCLinux

You may need a web server on your no-MMU embedded system in order to allow remote configuration or possibly provide external access to some files. Usually, you’ll need a lightweight webserver (e.g. not Apache) with the required features and in case of no-mmu system, source that can accommodates uClinux limitations such as no fork support. You’ll also take into account the programming language or the server: e.g. C/C++. Java, Ruby, Perl… If your system does not support Java or Perl for example, that may not be the best solution to add one of those only for the web server and it also depends on the resources (Flash/RAM) available. There are plenty of C/C++ lightweight http servers such as thttpd or lighttpd, however those are using fork in their code. One open source http server that is lightweight and uses vfork (instead of fork) is mathopd. At the time of writing, […]

Embedded Systems Hardware & Software Trends for 2011

VDC Research – a US company specialized in technology market intelligence – recently released two reports about embedded systems trends for 2011. The first report focuses on hardware and the second on software. The first report entitled “Top 10 trends for the embedded hardware and systems market in 2011” listed the following trends: COMs gain traction as time-to-market accelerators for OEMs By combining COM express modules with off-the-shelf COMs, suppliers are able to offer several different configurations of CPU boards and leverage COMs’ interchangeable characteristics. CPU vendors can thus offer a fairly wide range of boards without incurring high design and inventory carrying costs. PC/104 module family under pressure Although VDC data projects the PC/104 family will experience a single-digit rebound from the low points of the recent recession, vendors will have to commit resources to develop newer strategies in order for this technology to remain viable. Otherwise, the recovery […]
