Pulse-Sensing
Optical Mouse
Victor
Kremin & Serhiy Matviyenko
Victor
and Serhiy’s USB optical mouse enables you to measure
your pulse rate while you work at your PC. You can
design a similar system for numerous other sensory
applications. p.12
Keywords:
Mouse, optical, USB, pulse rate, pulsometer, TCRT5000,
CY8C24794, ADNS-2051, ADC, PSoC, PC, Delphi

Simplified
FSK Signal Detection
Dennis Seguine
Dennis
describes an efficient method for detecting FSK
signals using a correlator and analog signal processing
in a PSoC. The method is readily applicable to caller
ID technology. When combined with a UART, it forms
the core of a Bell 202 half-duplex modem. p.18
Keywords:
FSK, detection, PSoC, frequency, CY8C27443, UART,
modem, modulation, correlator

Programmable
Network Analyzer
James Gaston & Peter Hiscocks
James
and Peter used an oscilloscope and a waveform generator
to create a programmable network analyzer. The simple
system will be a great addition to your workbench.
p. 24

It’s time to get rid of the wires between your sensors,
slave devices, and the microcontrollers they serve.
Fred shows you how to move data wirelessly with
MaxStream’s XBee modules. Uncomplicated wireless
technology is at your fingertips. It doesn’t get
any better than this. p. 48
Keywords: Wireless, XBee, ZigBee, MC9S08GT60, MC13193,

Scheduler
Template for Microcontrollers
Praveen
Deshpande
Praveen
describes the process of writing a scheduler template
for a single-chip microcontroller. Although he used
this technique when he designed a real-time digital
wall clock, you can apply it to your next single-chip
microcontroller-based project. p. 60
Keywords:
Programming, scheduler, task, RTOS, AT89C2051, wall
clock, multitasking, IR remote, TSP1738, memory,
DS1307, ISR
