The Cypress USB driver (CyUSB.sys) is a robust high-performance Windows driver used for host communication with a USB-connected target. This driver is installed on the host PC as part of the EZ-USB FX2LP DVK installation, and in the accompanying zip file in the Windows Driver folder. The driver comes in binary form and can be distributed with your FX2LP-based devices. -
Page 28: Cypress Libraries
Detailed View of How Cypress Libraries Communicate with Applications The Bulkloop_VCS application is an example of the software architecture used for any Windows-to-FX2LP communication using the Cypress .NET library. A C# language program makes library calls that access the Cypress driver to communicate with FX2LP (see Figure 28). - Page 29 Communicating with USB devices using this high-level model is a great improvement over multiple Win32 API calls such as DeviceIOControl. An excellent way to gain familiarity with the Cypress library is to open the Bulkloop_VCS solution using Microsoft Visual C# Express edition, and inspect the code.

This application note explains how to implement an 8-bit parallel MPEG2-TS interface using the Slave FIFO mode. The example code uses the EZ-USB FX2LP at the receiver end and a data generator as the source for the data stream. Hardware connections and example code are included. - Page 37 This application note discusses how to configure the General Programmable Interface (GPIF) and slave FIFOs in EZ-USB FX2LP in both manual mode and auto mode to implement an 8-bit asynchronous parallel interface. This application note is tested with two FX2LP development kits connected back-to-back; the first one operating in master mode and the second operating in slave mode.
