2007 iEthernet Design Contest Winners
T
he WIZnet iEthernet Design Contest
2007 gave engineers throughout the
embedded design community a chance to
join the Ethernet revolution while competing
for a share of $15,000 in cash prizes and
international recognition. Designers from
around the world quickly stepped up to the
challenge by incorporating WIZnet’s W5100
hardwired TCP/IP Ethernet controller in
innovative embedded projects. Within weeks
of the contest launch, designers began
submitting their exciting, next-generation,
Ethernet-enabled embedded systems.
A
fter spending many long days and nights
closely studying the entries and judging
them on their technical merit, originality,
usefulness, cost-effectiveness, and design
optimization, the judges presented their
scores to the contest administrator. The
results are now final, and we’re proud to
announce the winners.
T
he irrigation timer with advanced
planning (ITAP) is a truly next-generation
irrigation con-trol system. Featuring a
WIZnet WIZ810MJ network module and an
Atmel ATmega168, the innovative controller
provides user interaction through a standard
web browser. As a result, the system doesn’t
have a keyboard or an LCD. The single-
controller unit can manage up to eight
zones. No software installation is required.
Its functionality is split between the browser-
based user interface and the hardware-based
web serv-er, data model, and control logic.
The web server is used to read and write the
internal data model.
I
ts other function is to return files stored
in internal program memory. Precision
irrigation control is now a reality because the
system provides useful information such as
watering schedules and zone activity.
