RS-485 Network for Embedded
Systems
by Shubhangi Ambekar
Integrating distributed
microcontroller-based systems can be a difficult
task, especially if you’re trying to do so in an
industrial environment. In this article, Shubhangi
shows you how she helped a former student automate
a solar panel production facility with an RS-485
network for embedded systems. p.12
Keywords:
RS-485,
network, distributed control, specifications, noise,
distance, termination, loading, node, control, isolation

Design
a Wide-Range RS-232 Concentrator Box
by
Daniel Wiklund & Tomas Henriksson
In the popular Scandinavian sport
of orienteering, competitors race through a forest
and record their progress via an electronic punching
system. In an effort to generate a bit more excitement
amongst the spectators, Daniel and Tomas designed
a concentrator box that immediately reports the
competitors’ split times to the contest administrator
at the finish line. p. 24
Keywords:
RS-232, concentrator, AT90S2313, current loop, MAX202,
signal level, data packet

Robert
spent nearly 100 hours building his high-performance,
LCD-based XY-Plotter. Now that he has written
about the process, it should take you much
less time to construct your own. Follow along
as he shows you how to maximize your time
and money when driving graphic LCD panels.

Glue Logic with Verilog HDL
by
Mark Balch
For reasons of availability and practicality, you
may soon find it necessary to design custom logic
for your digital projects. There are various design
techniques to choose from, but you’ll want one that
suits your specific needs. Mark explains how Verilog
HDL may prove to be the perfect solution for your
more complex digital designs. p. 52
