by Abigail
Krich
Abigail designed
a microcontroller-based, self-powered solar
data logger that uses a photodiode to measure
solar insolation levels. The system converts
the analog signal to a digital value that’s
stored in flash memory. p. 12
Keywords: Solar,
data logger, insolation, photovoltaic, ATmega32,
STK500, photodiode, ADC, LCD |

An MC16C/62P-Based RS-232 Analyzer
Nick Lott
Although RS-232
is disappearing from new devices, you’ll probably
have to work with it from time to time. You can
connect Nick’s M16C/62P-based system to an RS-232
device to determine the correct data rate, wiring,
and encoding scheme. You can also use it to monitor
a serial link. p. 20
Keywords: RS-232, M16C/62P, analyzer, wiring, data
rate, USB, ADC, DLP-USB232M

Multi-Input Temperature Logger
Nial Stewart
Nial designed
an FPGA-based multiple-input temperature logger
with an innovative USB interface. In this article,
he describes the FPGA logic to drive the sensors
and the flexible one-pin USB interface used to connect
it to a PC. p. 30
Keywords: Temperature, logger, FPGA, USB, 1-Wire,
Nios, EP1C20F400C7, DS1821, FT245RL, CPLD, EPM240T100,

Arby
An Arbitrary Waveform Generator with a Twist
Dhanajay Gadre, Pushkar
Sareen, Subodh Prabhu, & Sushas Chakravarty
The Arby is
an arbitrary waveform generator that can easily
generate any waveform. The eZ80F91 microcontroller-based
system enables you to input waveform requirements
in the form of an object-based program written in
any text editor and transmitted via the Internet.

Voltage Solutions
Harness the Power of Voltage Converters
Stuart Ball
Adding voltages
to your designs doesn’t have to be a complicated
task. Stuart explains voltage converter technology
and describes the basic principles behind the use
of voltage converters in simple designs. p. 46
Keywords: Voltage converters, inductor, spike, duty
cycle, negative voltage, Zener, charge pump, isolation,
transformer

Dive Into the ZigBee Pool
An Easy Way to Start Moving Messages
Fred
Eady
You don’t necessarily
need a ZigBee stack to move small messages from
point A to point B. Fred shows you a simple way
to get moving with the ZMB wireless sensor starter
kit. p. 50

LESSON FROM THE TRENCHES
Hello World ... Want Cookie
George
Martin
George is on
a mission to walk you through the process of creating
an embedded system, writing code in C language,
and then testing the design. In this article, he
takes a fresh look at C language and points you
in the right direction. p. 60
