Wireless Python Key To Mobile Robot
Programming wireless devices can be a chore, but the use of scripting languages like Python can turn rapid frustration into rapid development. I tested this theory with the Synapse Wireless EK2500 development kit, which I combined with iRobot’s Create here in the lab (see “Commanding The iRobot Create” at www.electronicdesign.com, ED Online ID ...

Multicore For WANs
The University of Southern California is the home of Tenet, a tiered wireless sensor network project. The architectures combine PC-class network masters with a horde of wireless micro motes that are typically 802.15.4 nodes. Generally, these are very low-power devices. Version 2.0 is available for download from the Tenet project’s Web site. The master tier runs on Linux or Windows (courtesy of Cygwin). The applications that run on...

Make Or Buy: Module Mania
Make it low-power. Buying off-the-shelf parts to meet these criteria is still a challenge, but the latest crop of modules makes the job easier. Modules let designers develop custom configurations with minimum moving the design of the critical aspects of the system to the module vendors. This includes the processor and memory subsystem and usually most, if not all, of the peripheral interface. A carrier board typically contains connectors and...

Core Hits 2 GHz With PCI Express Connectivity
Marvell took its ARM license and cranked out the 32-bit Shiva core, which hits 2 GHz and delivers PCI Express connectivity. It’s compatible with ARM’s 16- and 32-bit instruction sets even though it isn’t part of ARM’s Cortex push. This lets designers tailor the core to its requirements. The initial crop of Shiva chips targets multimedia applications, including portable units such as mobile Internet devices (MIDs). The 2-GHz 88F6281 ...

Shining A Light On Bugs
Turn on the lights and the cockroaches run away. This often seems to be the way to deal with programming bugs as well. Bring out the debugger or trace tools, and the problem goes away or remains difficult to locate. While application bugs don’t really react like real bugs, changing the state of an application’s environment does affect how buggy code responds. This is one reason why tools that impose no overhead on an application are...
