Light Therapy:
AC Phase Control for Changing
Power Outputs
Jeff Bachiochi
Jeff explains a high-tech lighting technique.
You can use AC phase control to create slow-changing
power outputs. Now you can truly control both the
look and feel of your environment. p.48

Finite
Machines and Microthreads
Massimo Manca
Massimo
shows you how to simplify finite state machine design
and implementation with only a C preprocessor. Now
you can translate UML state charts and activity
diagrams in C code. With Massimo’s macros, the work
is a snap. p. 52

by Fred Eady
APPLIED
PCs
Fred recently directed a GP-22050 waveform generator
to play the role of microcontroller in a simple
mechanical design. Read on to learn how he put a
mechanical design in “microcontroller mode” without
the help a microcontroller. p.62
Keywords: GP-22050, waveform generator, digital
I/O, LCD

Cyclic
Redundancy Check:
Understanding CRC Without
Math
Monte Dalrymple
Do
cyclic redundancy check (CRC) algorithms confuse
you? Monte takes the complicated math out of the
picture and uses the 32-bit polynomial used for
Ethernet to show you how they work. As you’ll see,
CRC hardware is fairly straightforward. p. 76
