The ICON Interface Module has been designed to work seamlessly with the
ICON H-Bridge module. The ICON Interface Module can act as a programming
platform for the ICON H-Bridge, as a stand-alone controller, or as a serial
interface between a master unit and the ICON H-Bridge.
This module provides all of the support circuitry to successfully implement
set-point DC motor control when used in conjunction with the ICON H-Bridge.
This circuitry includes a switching step-down regulator, 10-bit analogue-to-digital
conversion, indicator LEDs, frequency-to-voltage converter, and two channels
of 10-bit PWM generation.
The five modes of operation include two forms of motor speed control
with 0-4.096V analogue control input. One mode of operation makes use of
a frequency to voltage converter for speed control. A fourth mode of operation
allows the user to configure a custom motor speed profile that uses the
0-4.096V analogue input as the address for a look-up table containing motor
speed and direction information. And finally, motor speed and direction
can be controlled with a direct serial interface.
A multitude of configuration settings can be programmed via the serial
interface. These settings include the PWM frequency and resolution (the
default is 19.2kHz, 10-bit resolution), step limits for changes in the PWM
duty-cycle, and an expandable dead-band setting. Various function setting
registers and status registers can also be accessed with a serial link.
In addition to the various non-volatile configuration registers, the master
unit has free access to 16 EEPROM bytes stored in registers 19-34.
Ease of connectivity, a flash-based controller, and connections for in-circuit-debugging
allow the ICON Interface Module to be quickly configured for custom applications.
The unit measures 4.0" x 1.9" x 0.6". Motor connections are made via a screw
terminal.

ICON H-Bridge Module
The ICON H-Bridge provides easy connectivity and logic level control
of brushed DC motors to 40V and 12A. An on board microcontroller
can be accessed via standard serial communication, and provides
temperature and current monitoring, as well as user defined temperature
and current fuse settings.
ICON Serial Adapter
Simplifies connectivity of the ICON Interface Module to a PC. Provides
test points, analogue output, and connectivity to Microchip's DV164002
for customization of PIC16F873 firmware used on the ICON Interface
Module (see AN601).
ICON Position Controller
PID based position controller for use with brushed DC motors equipped
with quadrature encoders. Direct, Analogue, Velocity, or Trapezoidal
control modes with 32 bit position control. Can act as a stand alone
position controller or will work under control of a master unit.
Operates with the ICON H-Bridge configured in direct drive mode.
ICON Communication Module
The ICON Communication Module is designed to simplify testing and
development of projects requiring RS232 or RS485 serial communication
level conversion. The device can be mounted directly to the ICON
Interface Module, ICON Position Controller, or the Mini Position
Controller using supplied stand-offs and ribbon cable hardware.
ICON BS2 Carrier Board
This kit based on application note AN600 allows a single Parallax
BASIC Stamp 2 to control two ICON Interface Modules and the ICON
H-Bridges connected to them. This assembly is ideally suited for
medium sized robotics projects. Various application notes are available
to support this product.
