This article is about the Bluetooth wireless specification.
Bluetooth is an industrial specification for wireless personal area networks (PANs) first developed by Ericsson, later formalized by the Bluetooth Special Interest Group (SIG). The SIG was formally announced on May 20, 1999. It was established by Sony Ericsson, IBM, Intel, Toshiba and Nokia, and later joined by many other companies as Associate or Adopter members.
The system is named after a Danish king Harald Blåtand (Harold Bluetooth in English), King of Denmark and Norway from 935 and 936 respectively, to 940 known for his unification of previously warring tribes from Denmark, Norway and Sweden. Bluetooth likewise was intended to unify different technologies like computers and mobile phones. The Bluetooth logo merges the Nordic runes for H and B. This is the official story: however, the actual Harald Blåtand that was referred to in naming Bluetooth was most probably the liberal interpretation given to him in The Long Ships by Frans Gunnar Bengtsson, a Swedish best-selling Viking-inspired novel.
Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers and digital cameras via a secure, low-cost, globally available short range radio frequency.
Bluetooth lets these devices talk to each other when they come in range, even if they're not in the same room, as long as they are within 10 metres (32 feet of each other).
Compatibility of products with profiles can be verified on the Bluetooth Qualification website (http://qualweb.bluetooth.org/Template2.cfm?LinkQualified=QualifiedProducts).
Comprehensive Real-World Guidance for Every Embedded Developer and Engineer
This book brings together indispensable knowledge for building efficient, high-value, Linux-based embedded products: information that has never been assembled in one place before. Drawing on years of experience as an embedded Linux consultant and field application engineer, Christopher Hallinan offers solutions for the specific technical issues you’re most likely to face, demonstrates how to build an effective embedded Linux environment, and shows how to use it as productively as possible.
Hallinan begins by touring a typical Linux-based embedded system, introducing key concepts and components, and calling attention to differences between Linux and traditional embedded environments. Writing from the embedded developer’s viewpoint, he thoroughly addresses issues ranging from kernel building and initialization to bootloaders, device drivers to file systems.
Hallinan thoroughly covers the increasingly popular BusyBox utilities; presents a step-by-step walkthrough of porting Linux to custom boards; and introduces real-time configuration via CONFIG_RT--one of today’s most exciting developments in embedded Linux. You’ll find especially detailed coverage of using development tools to analyze and debug embedded systems--including the art of kernel debugging.

This document is an introduction to the use of Bluetooth for embedded control applications.? Although there are many resources that discuss Bluetooth for wireless headphones, keyboards, mice, and similar uses, this document is confined to the advantages and potential pitfalls of using Bluetooth for embedded control.
PC-104 CPU Module targets entry-level applications.
Bundled with Linux OS, AR-B8020 addresses applications that only need 386 or 486 level CPU to execute basic industrial applications. Fanless CPU board, compatible with X86 S/W structure, employs 133 MHz RDC R8610 CPU and offers 64 MB onboard SDRAM. Expansion is made possible via PC/104 and PCI-104 expansion slots, and connectivity options include 2 USB 2.0, 3 COM, and 10/100 Mbps LAN interfaces …

Designed for headless space- and power-limited systems in medical, communications, security, transportation, utilities, Mil/COTS, and industrial test/measurement applications, it has two Ethernet, four USB 2.0, and four asynchronous serial channels plus connectors for both PC/104 and Mini PCI I/O cards. It measures 90mm x 96mm (3.6” x 3.8”), draws 5.5W, and will operate from -40°C to +85°C without a fan.
The PCM-VDX-2-512 is based on DM&P’s Vortex86DX processor and is populated with 512MB of soldered-on DDR2 SRAM plus 1MB SRAM. Its x86 architecture runs Linux, DOS, and other x86 operating systems. This SBC is supplied with downloadable drivers which are available from WinSystems’ website.
Electrostatic Discharge (ESD) suppressors rated to ±15kV are included on the USB, Ethernet, and serial data ports for additional protection and will withstand multiple ESD strikes. Additionally, the USB ports have in-rush and over-current protection. All four independent, full-duplex serial channels support RS-232/422/485 levels and operate at data rates up to 115.2 Kbps.
The PCM-VDX-2-512’s PATA controller supports a CompactFlash card and an IDE drive. Other onboard peripherals include 16-lines of digital I/O, PS/2 keyboard and mouse controllers, LPT interface, real time clock, watchdog timer, activity LEDs, and a piezo speaker for BIOS status beep codes. Mini PCI and PC/104 connectors support expansion I/O cards for wireless networks, video, etc. With this diverse range of functions, many applications will not require any additional I/O cards.
WinSystems can customize this SBC for OEM applications either by depopulating certain features or by adding soldered-on flash memory, a CF card retention clip, and/or a Mini PCI video card. The processor speed and amount of SDRAM can be reduced to lower the price and power consumption as well.
The PCM-VDX-2G-512 in OEM quantities is $342. Delivery is from stock to three weeks. WinSystems’ offers a 30-day product evaluation program.

Aaeon announced a PC/104 CPU module equipped with the Intel Atom N450 processor. The PFM-LNP supports simultaneous dual-view displays, has an 18-bit single channel LVDS interface, provides PCI/104 and Mini-PCIe expansion, and offers gigabit Ethernet, USB 2.0, and serial connectivity, says the company.
The PFM-LNP module is designed for transportation devices, kiosks, building automation, factory automation, and instrumentation, says Aaeon. Like the company's COM-LN COM Express module introduced earlier this month, the PFM-LNP is equipped with an Intel "Pineview" Atom, in this case the N450 clocked to 1.66GHz. The processor is mated with Intel's ICH8M chipset, as well as up to 1GB of DDR2 667Mhz memory, says Aaeon.

Two new PC/104-compatible analog I/O cards have been developed by WinSystems. The PCM-MIO-G-AD-1 is a 16-channel, 16-bit analog input card and the PCM-MIO-G-DA-1 is an 8-channel, 12-bit analog output card. Both cards also support 48 lines of digital I/O.These small (90 x 96 mm) expansion boards are designed to meet customer requirements for accurate analog and digital I/O over a -40°C to +85°C temperature range. They are designed for industrial, medical, security, transportation and Mil/COTS applications.
Based upon Linear Technologies’ precision converters and voltage references, these cards do not require calibration, which results in quick, easy setup, as well as eliminating the necessity for readjustment and recalibration to installed units in the field.The input ranges for the PCM-MIO-G-AD-1 are 0–5 V, ±5 V, 0–10 V and ±10 V. Two independent, 16-bit A/D converters support up to 16 single-ended or eight differential channels or various combinations of both. The conversion speed is 100 KSps.
The PCM-MIO-G-DA-1 has eight independent, 12-bit D/A converters on board. The output voltage ranges are 0-5 V, 0-10 V, ±5 V, and ±10 V. All output channels are programmable and can be updated and cleared individually or simultaneously.Both boards have 48 lines of digital I/O individually programmable for input, output or output with read-back. The lines are TTL compatible and can sink 12 mA which supports direct connection to optically isolated AC and DC signal conditioners. Both cards are supplied with free drivers for C, Linux and Windows XP Embedded.
