AN1193 - Using Timer Interrupt in Cypress EZ-USB
FX2LP™ Based Applications
This application note is aimed at helping EZ-USB
®
FX2LP™ based firmware developers use
timer interrupts in their applications, by providing a framework based timer interrupt program writ-
ten in C. The assumption is made that one has a general understanding of how interrupts work
within the 8051 concept. When this program is run, you should be able to light the seven-seg-
ment LED on the FX2LP Development Board (CY3684) with a 0-9 count, and control the step
rate (1s - 5s) using BULK OUT endpoint transfers from the EZ-USB Control Panel.
AN63787 - EZ-USB FX2LP™ GPIF and Slave FIFO Configuration Examples using FX2LP Back-
to-Back Setup
AN63787 discusses how to configure the general programmable interface (GPIF) and slave
FIFO's of EZ-USB FX2LP™ in both manual mode and auto mode, to implement an 8-bit asyn-
chronous parallel interface. This Application Note is tested with two FX2LP development kits con-
nected in back-to-back setup; the first one acting in master mode and the second in slave mode.

AN61244 - Firmware Optimization in EZ-USB
The EZ-USB
®
family of chips has an 8051 core and uses the standard 8051 instruction set. How-
ever, it has a few enhancements compared to the standard 8051. This application note describes
firmware optimization methods in EZ-USB. Some of these methods are common for any proces-
sor and some specific to the 8051 core of EZ-USB.
AN70983 - EZ-USB FX2LP™ Bulk Transfer Application in C# Using SuiteUSB C# Library
(CyUSB.dll)
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 docu-
ment also explains associated firmware used in FX2LP to implement loopback transfers on bulk
endpoints, and the application is tested with FX2LP Development kit.
AN70486 - EZ-USB® FX2LP™ Host Application in VC++ 2008 Using Suite USB Library
(CYUSB.dll)
This application note demonstrates how to build a host application on Microsoft Visual C++ plat-
form, 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.

FX2LP™ - Developing USB Application on MAC OS X using LIBUSB
AN74505 describes a host application built on the MAC OS platform that uses libusb. The host
application (Cocoa Application) communicates with the BULK IN and BULK OUT endpoints of
FX2LP, using the interfaces provided by the APIs of libusb. This host application implements the
transfer only with devices that pass the particular VID/PID(=0x04B4/0x1004) identification.
AN6077 - Implementing an 8-Bit Asynchronous Interface with FX2LP™
AN6077 discusses how to configure the general programmable interface (GPIF) and slave FIFOs
of the EZ-USB FX2LP™ to implement an 8-bit asynchronous interface. The GPIF is a program-
mable 8- or 16-bit parallel interface that reduces system costs by providing a glueless interface
between the EZ-USB FX2LP and different types of external peripherals. The GPIF allows the EZ-
USB FX2LP to perform local bus mastering to external peripherals implementing a wide variety of
protocols. For example, EIDE/ATAPI, printer parallel port (IEEE P1284), Utopia, and other inter-
faces are supported using the GPIF block of the EZ-USB FX2LP. In this example, it masters the
slave FIFO interface of another EZ-USB FX2LP.
