| Cypress’s FX2LP is one of the most popular programmable high-speed USB controllers in the industry. Cypress provides SuiteUSB for creating windows applications using Microsoft Visual Studio. This application note demonstrates how to build a host application on Microsoft Visual C++ platform, using the Cypress SuiteUSB C# library, CyUSB.dll, to perform USB BULK IN and OUT transfers with FX2LP and the associated project is tested with FX2LP Development kit. |
Overview
AN70486 describes a host application built on the Microsoft Visual C++ 2008 platform that uses CyUSB.dll to communicate with Cypress USB driver, CyUSB.sys. The host application communicates with the BULK IN and BULK OUT endpoints of FX2LP, using the interfaces provided by the APIs of CyUSB.dll. The CyUSB.dll in-turn communicates internally with Cypress USB driver (CyUSB.sys), for talking to these endpoints. This host application implements the transfer only with devices that pass the particular VID/PID identification. The example device used in this application note is the Bulkloop device. The firmware that is attached along with this application note causes a loop back of data inside the device. Thus this host application, with the attached Bulkloop device, demonstrates the loopback of data.
