Generation 2 and generation 3 technology stacks are very similar at the application layer. Porting an application from generation 2 to generation 3 technology stack in quite easy and well documented in user friendly porting guides.

Generation 2

Users can write their application code in C/C++ using the DEWESoft TE USB API. The application code shall use handles.
Sample application projects:

• https://github.com/Trenz-Electronic/TE-USB-Suite/tree/master/TE_USB_FX2.gen_2

Generation 3

Users can write their application code

...

The application code does not use handles.
If the user wants to develop and launch an application or system service (e.g. a Plug and Play application or system service), he/she can call any useful functions or methods from CyAPI (in C++ only), TE_USB_FX2_CyAPI (in C++ only), CyUSB (in any .NET programming language) or TE_USB_FX2_CyUSB (in any .NET programming language).

TE_USB_FX2_CyAPI.dll (C++)

Documentation:

• C++ TE_USB_FX2 API reference manual (UM-TE_USB_API.cpp .pdfReference Manual)
• DEWESoft C++ DLL to Trenz Electronic C++ DLL Porting Guide (UM-TE_USB_API.cpp .PortingGuide.pdf)Porting Guide)

Application code examples:

• C++ software projects templates and reference applications are available here.

Compiling C++ applications:

• Users can write their own C++ applications by including the FilesToImportForApplicationCpp.zip package.
• C++ application code can access CyAPI.lib classes and functions directly to extend TE_USB_FX2_CyAPI APIs.
• C++

...

• applications using Qt can be easily compiled with Microsoft Visual Studio 2010 Professional and the Qt Visual Studio Add-in on QtProject.org.
• There is no difference between compiling C++ applications for 32 bit Windows operating systems with Microsoft Visual Studio Express and Microsoft Visual Studio Professional.

• There is some difference between compiling C++ applications for 64 bit Windows operating systems with Microsoft Visual Studio Express and Microsoft Visual Studio Professional. Such differences are explained in the C++ TE_USB_FX2 API reference manual (

...

• here).

...

• C++ applications

...

• for 64 bit Windows operating systems with Microsoft Visual Studio

...

• Express requires also Microsoft Windows SDK 7.1

  Note
  The staightforward procedure to install both Microsoft Windows SDK 7.1 and Microsoft Visual Studio 2010 Express on the same computer will fails: see here. In this link, 2 different procedure are described; we have sucessfully tested both procedures.

TE_USB_FX2_CyUSB.dll (C#)

Documentation:

• C# TE_USB_FX2 API reference manual (UM-TE_USB_API.cs .pdfReference Manual)
• DEWESoft C++ DLL to Trenz Electronic C# DLL Porting Guide (UM-TE_USB_API.cs .PortingGuide.pdf)PortingGuide)

Apllication code examples:

• .NET software projects templates and reference applications are available here.

Compiling C# applications:

• Users can write their own .NET applications by including the FilesToImportForApplicationCsharp.zip package.
• .NET application code can access CyUSB.dll classes and methods directly to extend TE_USB_FX2_CyUSB API.

Simplified TE_USB_FX2_CyAPI.dll (C++)

Documentation: .NET software projects templates and reference applications are available here.

• Dewesoft C++ DLL to Simplified Trenz Electronic C++ DLL (UM-SimplifiedTE_USB_API.cpp Porting Guide)

Apllication code examples:

• Open_FUT (generation 3)

Compiling C++ applications:

• Pure extern C code library simplified version of TE_USB_FX2_CyAPI (C++) APIs.
• Ease binding to/from Python (ctype) or another programming language
• Impossible to directly access CyAPI.lib classes and functions to extend Trenz Electronic TE_USB_FX2_CyAPI.dll libraries
• It is not thread safe

Open_FUT (generation 3)

Open_FUT (generation 3) has been developed in CPython by using a pure extern C code library version of TE_USB_FX2_CyAPI APIs (codename: simplified TE_USB_FX2_CyAPI APIs).
Open_FUT could be ported to .NET by

• using TE_USB_FX2_CyUSB librariesinstead library instead of the simplified TE_USB_FX2_CyAPI librarieslibrary;
• using .NET Trenz Electronic USB FX2 APIinstead API instead of the simplified C/C++ Trenz Electronic USB FX2 APIs;
• using Microsoft WF (Windows Forms) or Microsoft WCF (Windows Communication Foundation) instead of Tkinter (Tkinter is not well supported by .NET);
• using IronPython (or Python for .NET package) instead of Python ctype with CPython.
