Overview
 

Cypress GPIF Designer allows the user to create and modify GPIF waveform descriptors for the EZ-USB FX and FX2 chips using a graphical user interface.

The main window consists of 5 tab pages. The first page presents a block diagram representing the logical connection of the the FX/FX2 to an associated slave device.

Each of the remaining four pages contains a waveform editor.  These editors enable the creation of 4 distinct GPIF state machines or "waveforms".

As a general rule, existing settings can usually be modified by right-clicking the mouse on the region where the setting is displayed.  This applies to both the block diagram and the waveforms.

Waveforms are modified by placing, moving or modifying Action Points on various waveform Bands.  Use the left mouse button to place or drag action points.  Use the right mouse button to modify an existing action point.

 

An extensive discussion of general GPIF functionality and programming is distributed as a General GPIF User's Guide, accessible from the main Help menu.

PDF (Adobe Acrobat) files of a GPIF Primer as well as the FX and FX2 Technical Reference Manuals are located in the PDFs sub-directory within GPIF Designer install directory.

Also, design examples provided by Cypress include on-line application notes for those examples.  Those notes are automatically loaded when the project's *.gpf file is opened.  (See the Help section of this User's Guide for more information.)
