Gary Livick contributed a servo
driver that works on the Port A, bit 3 pin (the beeper pin). He says
it works even if you leave the beeper connected (and don't mind a
little clicking). See his message including source code.

Curt Mills, WE7U has been working
on Handy Board libraries for the gcc/hc11 compiler. Download the
patches to make gcc work with the 68HC11 and also the Handy Board
libraries at his FTP
site. See also Curt's home
page.

Barry Brouillette developed a tutorial
and software drivers for using the fantastic Sharp GP2D02 optical
distance sensor with the Handy Board. The Expansion Board is
required.

Richard Drushel's
improved serial and math libraries.
16-Channel IR Proximity Sensor. Keith Soldavin contributed a schematic and a description of a 16-channel IR
modulation and detecting circuit, for proximity sensing.
Versatile IR Transmit and Receive. Max Davies has developed infrared receive and
transmit routines that work with many different manufacturers'
IR-remote protocols.

Vector 2X Digital Compass. Tom Brusehaver has contributed
information on connecting the Vector 2X compass to the Handy Board.
Download the compass.zip archive,
or browse the readme file, the schematic, assembly language source, compiled ICB driver, or support C file.
Sonar Routines. Kent
Farnsworth has contributed information and drivers for using the
Polaroid sonar ranging module with the Handy Board. See his readme
file and his hbsonar directory. Note: the official
Handy Board sonar drivers are now available in the Software/Libraries section.
Multi-Driver Sonar
Schematic. Contributed by Adam Cox.
Smooth PWM Routines.
Julian Skidmore implemented a
new algorithm for performing the pulse width modulation on the Handy
Board's motors, allowing up to 100 power steps rather than just
eight. Download the new pcode_hb.s19 file and new lib_hb.c file. Also available is
the modified pcode_hb.asm source file, and a
modified makefile.
