Logic Analyzer and pulse generator

ECE 682

The specification

Specification was handed out in ECE 582 last quarter. Basics

3 channels – dedicated output 3 channels – dedicated input 2 channels – configurable as either a dedicated input or output Signals up to 5 MHz was desired – unit from Fall 2006 ~2kHz Interface to host computer using USB – was accomplished

The software

A very important part of this project is the software system that accompanies it

Unit is not really usable without it!!!! Software

Configure the programmable lines Configure the outputs and download the information need to the

unit for generation of the signals Received data over the USB that can be displayed in a window

on the host PC as to the state of the signals being monitored. Prior project – all 8 lines were programmable as input or

output.

Many, Many, Many design decisions What goes in the “box” Format of data for storage and transfer

over the USB link How much local storage is needed? USB 2.0 standard Programming Language

Several systems exist in the “real” world National Instruments has such a unit

Check it out on the web GoLogic System by NCI.
