Innovation 2003 Design Contest Winner
Alberto’s 68HC908QT4-based multimedia
thermometer displays temperature readings in full
color on a TV screen. What’s more, you can add animated
pictures along with high-quality audio to announce
each temperature change. If you don’t need a temperature-taking
system, you can use the design techniques described
here to display any other type of data. p. 12
Keywords:
Temperature, thermometer, multimedia, DVD, IR, remote,
RECS-80. DS1621, MC68HC908, pulse generator, SAA3004

of a full field of color video. Use this circuit
for digital, freeze-frame, and motion-triggered
camera design projects. p. 22
Keywords:
Frame grabber, video, color, SAA7113, ATmega8535,
NTSC, ITU-R BT601, ITU-R BT656, digitize, FPGA,

by Robert Lacoste
When designing high-speed
applications, working with SMT components
and soldering by hand can be tedious. Robert’s
H8/3687-based SMT Reflow Oven Controller transforms
a conventional infrared toaster oven into
an effective reflow oven that ensures thermal
control. p. 32
Keywords:
Oven, reflow, SMT,
temperature control, preheat, stabilization,
infrared, AD595, EVB87, BasicATOM, LCD, H8-3687

Designing
with the Nios (Part 2)
System Enhancement
George Martin
Last month, George laid the groundwork for a Nios-based
two-axis motion control system. Now he discusses
velocity feedback and preps you on the software
you’ll need to drive it. p. 36
Keywords:
Nios, FPGA, AD7476, SPI, LAN91C111, SOPC Builder,
UART, timer, I/O, motion control

Triple AVR Waveform Capture and Display
Three Controllers Make a Waveform Monitor
Dick
Cappels
Dick built a simple waveform capture and display
system around three AT90S2313 microcontrollers.
Although it’s not a replacement for a real-time
oscilloscope, he relies on the system for a variety
of tasks such as monitoring the I/O on a microcontroller.
p. 42
Keywords:
Waveform monitor, AT90S2313, oscilloscope, LCD,
user interface

Uncomplicated dsPIC Implementation
Fred
Eady
As soon as Fred got his hands on a Microchip dsPICDEM
28-pin demo board, he modified it. This month he
proves that you don’t have to be a DSP wiz to get
started with the dsPIC. p. 50
Keywords:

Smart-E-Touch
An Intelligent User Interface
Bruce
M. Pride
Bruce’s Smart-E-Touch is an intelligent, touchscreen-based
UI design in which a 68HC908QY4 microcontroller
controls a pair of Motorola e-field sensors. This
inexpensive system is the perfect alternative to
the pricier touchscreen UIs on the market. p.

Brian has created a graphics library you can use
for your future projects. It provides access for
Encore! programs to graphics LCD panels driven by
the T6963 LCD driver chip. p. 62
Keywords:

There are many different silicon oscillators out
there, but Jeff thinks the LTC6903 is a standout.
Read on to learn how he used it with a microcontroller
to control a four-digit LED. p. 74

Motor Basics
Tom Cantrell
Intelligent motor control should be the only kind
of motor control you design into your projects.
But before you start sketching your next design,
take some time to learn about the electric motors
at your disposal. Tom covers them all, from brush
to brushless. p. 78
