Development Kit Contents
4.5 GPIF_Designer
This directory contains the GPIF designer software, which allows you to create State machine wave-
forms. These waveforms are useful to communicate with external devices, such as SRAM and
FPGA, using an EZ-USB GPIF interface.
4.6 Hardware
This directory contains the EZ-USB hardware schematic, PCB, Layout, gerber, and PCB BOM files.
Following are the files in this directory.
4.7 SuiteUSB
This folder contains the SuiteUSB 3.4.7 installer package and a sample Cypress Software License
agreement document. The software is installed as part of the EZ-USB Kit installer and the contents
are, by default, located at
C:\Cypress\Cypress Suite USB 3.4.7
.The package contains C++
9 LEDCycle
Simple firmware example to demonstrate use of the general-purpose indicator
LEDs (D2, D3, D4, D5) on the development kit board.
10 Pingnak
Contains firmware to perform bulk loopback of EP2OUT to EP6IN and EP4OUT to
EP8IN using the PING NAK interrupt to initiate the transfer.
11 iMemtest Memory test firmware example. Tests on-chip RAM.
12 vend_ax
Contains the source files to build a vendor-specific command sample. This example
demonstrates how to implement different vendor commands.
