 We are following with huge excitement the progress of Raspberry Pi, An ARM GNU/Linux box for $25.
The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It's a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games.
They offer 2 versions: Model A ($25) that has 128Mb of RAM, one USB port and no Ethernet (network connection) and Model B ($35) has 256Mb RAM, 2 USB port and an Ethernet port.

 In CISIUM one of our strategic markets is the Bluetooth communications. Bluetooth is intended for portable equipment and its applications. Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions in the ISM band from 2400-2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.
The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in a variety of personally carried applications in any setting and can also support fixed location applications such as smart energy functionality in the home (thermostats, etc.).

 One of the most important middleware is the TCP/IP stack. In full operation systems like Linux, Windows, Android, iOS, etc. the stack is already integrated, but in tiny real time operation systems, like FreeRTOS,FreeRTOS, ChibiOS/RT, etc. usually the TCP/IP stack in not integrated.
The TCP/IP model (Transmission Control Protocol/Internet Protocol) is a descriptive framework for the Internet Protocol Suite of computer network protocols created in the 1970s by DARPA.

 The middleware is a fundamental part of any electronic embedded development. In CISIUM we have adopted FatFs is a generic FAT file system module for small embedded systems.
File Allocation Table (FAT) is the name of a computer file system architecture and a family of industry standard file systems utilizing it. The FAT file system is technically relatively simple yet robust. It offers reasonably good performance even in light-weight implementations and is therefore widely adopted and supported by virtually all existing operating systems for personal computers. This makes it a well-suited format for data exchange between computers and devices of almost any type and age from the early 1980s up to the present.

 The connection of electronic embedded products to internet is one of the biggest trends of many things that surround us.
CISIUM has joint to the openPICUS platform made of the free software IDE and modular hardware - modules and expansions - in order to let your systems to be connected and controlled from anywhere. This technology offers an easy way to connect and control embedded systems over Internet through a custom webserver or the standard TCP/IP services. The platform is composed by:
- openPICUS IDE: a free development tool for creating, compiling and downloading applications (firmware), for importing web pages and interacting with the Communication Stack
- Bootloader: it's loaded on modules and allows to download firmware on them with no need of investing in expensive hardware programming systems.
- Hardware: modules and expansion boards (Nests) for creating complex systems.
