88 Parallax BASIC Stamp (Robotics Microcontroller)
Description
This article is from the Robotics FAQ, by Kevin Dowling nivek@cs.cmu.edu with numerous contributions by others.
88 Parallax BASIC Stamp (Robotics Microcontroller)
The Stamp is a 1x2" (2.5x5cm) computer that runs BASIC programs
written on a PC. 8 I/O lines which can be used for serial
communications, potentiometer inputs, pulse measurement, switches,
speaker drivers etc. Usually you'll have to add no more than a
resistor or capacitor at most. A BASIC editor on the PC converts
instructions into token that are downloaded to the Stamp via a
3-conductor cable and stored in EEPROM. Whenever the Stamp is powered
up, the on-board interpreter runs the program. Battery clips are built
in for a 9V battery (Stamp has 5V supply built in.) and the Stamp has
a small prototyping area as well. From Digikey the Development Kit
(including a Stamp) is $139, and a Stamp is $39.
There is a BASIC STAMP Mailing List (NOT a newsgroup)
stamp-list@cybernetics.net Subscribe to it by sending mail to
majordomo@cybernetics.net with a line of text saying
subscribe stamp-list There is also an FTP site at "novell.nrc.ca" that
has a STAMP directory structure. It contains (so far) all the stuff
from the Parallax BBS, plus a few other goodies.
[18.8] National Semiconductor LM628/629 (Robotics Microcontroller)
Small motor control chip. Does PWM for motion control at a very low
cost. A couple of H-bridges on the outputs. Good reference for using
the 628/9 for motion control is in: Closing the Loop on DC Motor
Control by Tom Dahlin and Don Krantz The Computer Applications

[18.9] Hewlett-Packard HCTL 1000, 2000 (Robotics Microcontroller)
HP's motor and encoder interface chips. Widely used and widely
available.
