Last Updated: 12/19/2012
Version: *A
AN70983 demonstrates how to build an application on Visual C# to send bulk data out and receive it back over a bulk endpoint of FX2LP, which is developed using Cypress SuiteUSB C# library (CyUSB.dll) for creating Windows applications using Microsoft Visual Studio. This document also explains associated firmware used in FX2LP to implement loopback transfers on bulk endpoints, and the application is tested with FX2LP Development kit.

Overview

Cypress EZ-USB FX2LP™ is one of the most popular programmable high-speed USB controllers in the industry. This application note has two parts.

Host application: This application is built on the Microsoft Visual C# 2008 platform. The application communicates to BULK IN and BULK OUT endpoints of  FX2LP™ using the interfaces given by CyUSB.dll. The CyUSB.dll, in-turn communicates internally with the Cypress USB driver CyUSB.sys, for talking to these endpoints.

Target firmware: This describes related firmware residing on target, which transfers the data sent from the host application on BULK OUT endpoint to the BULK IN endpoint, for sending it back to the host application in loopback fashion.
