The Eclipse IDE has been used for embedded development for many years now, but it has always been a painful process to setup and use. In a couple of weeks version 3.5 of the Eclipse framework codenamed 'Galileo' will be released. At the same time the CDT team are planing to release version 6.0 of the C/C++ Development Tooling plugin. What makes this interesting to the embedded development community is that the Debugger Services Framework (DSF) has been integrated into this CDT release. The DSF provides an alternative to the Standard Debug Model API of the Eclipse platform and has been designed to help achieve better performance when debugging applications on slow or remote targets.
To gauge how painless it really is is use the new version of Eclipse for embedded development we decided to give the current release candidate a try. We downloaded the "Classic" package and installed the CDT, Remote System Explorer (RSE) and Subversion source control plugins. The creation and cross-compilation of a simple "Hello World" application was straight forward. The setting up and configuration of the connection to the remote device (using SSH) was slightly more complicated, but worked well. The integrated remote file viewer, shell and GDB launcher are all very useful tools that make Eclipse that much better as an embedded device development IDE. So perhaps now Eclipse is finally ready for embedded development!
We have added detailed instructions on how to setup and use Eclipse with our Snapper 9260 Quickstart Kits on the Bluewater quickstart pages.

Embedded development boards have, in the last few years, progressed from being expensive platforms only available to professional or commercial developers, to almost-commodity devices accessible to anybody with an inclination to tinker. In the same time, the processing power available has progressed from cramped 8-bit micros to something resembling a previous-generation desktop, in a board the size of a deck of cards. As a result, there has been an emergence of hobbyist devices, ranging from the intimidating to the inane, of which we'll highlight a few here.
Deeply impressive: Autonomous Trans-Atlantic Sailboats
The Microtransat Challenge is a trans-Atlantic race of fully autonomous sail boats, designed to stimulate development of autonomous sailing boats. There are currently 12 teams registered for the 2009 race, with control systems ranging from commodity PC hardware to a custom FPGA-based system PCB. Resilience, intelligence, a wide range of sensor options and energy efficiency are key to success for these boats – a task to which modern embedded processors are ideally suited.
Inevitable, in a way: RFID Cat Doors
[From: http://ioanghip.googlepages.com/catdoor – controller laptop not shown]
The key to invention is to recognise a need, and address it. In this case, the need is controlling the use of a cat door - whether to prevent other cats entry, or to control what the cat is allowed to bring in with it. In both these cases, the hacked-together prototype is a mishmash of commodity desktop computer hardware and components - a mixture that ideally lends itself to being simplified through the use of a smart embedded controller.
While this may seem like an obscure product, commercial variations now exist:
RFID Cat Door
Pet Porte® Microchip Cat Flaps
Just cool: Persistence-of-Vision LED Bike Lights
Persistence-of-vision means that rapidly-moving light sources will appear to be present for longer than they actually are, in this instance allowing a rapidly spinning line of LEDs to appear as a solid surface. Combine this with a small micro-controller, a sensor capable of determining rotational position, and you have the ability to display arbitrary images – or to turn your bicycle into a stunning mobile billboard.
Again, this appears to be a fairly niche device – more of a toy than anything – but it has been commercialised by a number of companies:
MonkeyLectric Monkey Light
Pimpstar Dub Custom Wheels
The focal point here is that the line between hobbyist and commercial development is blurring: build something interesting, and you might find people lining up to give you money.
