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.
