1 Introduction
This section gives a brief description of the SMT1026 package.
The SMT1026 is a SDK for Windows.
The SMT1026 is an efficient, ready to use, host side interface to Sundance FPGA-only
module. It allows you to control the FPGA-only modules from the host as well as to
exchange data between the host and the module on the first site of the Sundance carrier
board.
The figure above shows the SMT1026 forming the link between your application and the
Sundance hardware in your system. The SMT1026 hides the details of the device driver,
allowing you to concentrate on the development process.

2.2 Prerequisites
The language C++ is used for the software interfaces. Even if you are not familiar with
C++, you should be able to find your way by referring to the samples. The samples have
been compiled and tested with Microsoft Visual Studio 2010, express edition.
2.3 Software Installation
This section describes how to install the SMT1026 package.
•
•
•
From CD
Visual Studio Configuration
Visual Studio 2010 Configuration
2.3.1 Software Installation From CD
Insert the SMT1026 CD into your CD drive. The setup program should start
automatically; if it doesn’t you can start it yourself by opening an Explorer window,
browsing to the CD, and then double-clicking setup.exe. The installation program will
give you the option of installing samples. We recommend that you become familiar with
the SMT1026 by installing and reviewing the sample code.
The default directory is “C:\Program Files\Sundance\SMT1026”.
The applications need access to smtFPGA.h and smtFPGA.lib. You need to arrange that
these files can be found during compilation and linking. We strongly recommend that you
do not make copies of these files, but access them from the installation directory. See
the Visual Studio Configuration for more details.
2.3.2 Visual Studio Configuration
The installation process configures the examples to compile and link correctly without
any user intervention. However, for your own applications, you need to configure visual
studio to add the paths to the include and lib directories to your compiler options.
You do this as follows:
•
•
•
•
•
•
•
2.3.3
Open Visual studio.
Select "Tools->Options" from the menu.
Select the “Directories” tab.
Select “Include files” from the "Show directories for" drop down list.
Add the path to the include directory for the SMT1026 installation to the list of
directories.
Select “Library files” from the "Show directories for" drop down list.
Add the path to the library files for the SMT1026 to the to the list of directories.
Visual Studio express 2010 Configuration
The installation process configures the examples to compile and link correctly without
any user intervention. However, for your own applications, you need to configure visual
studio to add the paths to the include and lib directories to your compiler options.
You do this as follows:
•
•
•
•
•
•
•
Open Visual studio express 2010.
Select "Project->Properties" from the menu.
Select the “VC++ Directories” in “Configuration properties” on the left of the
window.
Select “Include directories” on the right of the window.
Add the path to the include directory for the SMT1026 installation to the list of
directories, as shown below.
Select “Library directories” on the right of the window.
Add the path to the library files for the SMT1026 to the list of directories.
3 Software
This section describes the functionality of the SMT1026 package.
3.1 Interface Mechanism
The design makes use of a C++ style interface pointer to the hardware.
SmtFPGA.dll exports functions that gather information about the installed boards and
provide an interface pointer for later use.
To use the SMT1026, you need to:
•
Obtain an interface pointer to the hardware by calling
SmtxxxOpen(unsigned
int nIndex = 0).
•
Use the interface pointer to call functions related to the hardware.
Example:
// Open the SMT391 library
IFSmt391 *pSmt391 = Smt391Open(0);
pSmt391->ResetTIMs();
// Configure the FPGA
pSmt391->ConfigureFPGA(BITSTREAM, QUICK_CONF);
3.2 Functions exported by SmtFPGA.dll

5 Examples
The SMT1026 provides several examples to illustrate the used of the Sundance's FPGA
library.
There is an example for each supported FPGA module and a more generic one.
Those examples are organised in three folders:
•
•
•
Firmware
Host
Output
5.1 Firmware
This folder contains several firmware for the FPGA-only module.
It's installed in the following directory: "C:/Program
Files/Sundance/SMT6026/Examples/SMT391/Firmware".
Remark: SMT391 can be replaced by the number of the board you are interested in.
The bitstream have been compiled with 3L Diamond FPGA and therefore are *.app files.
The "readme.txt" file contains some information about the firmware. The source code can
be provided on demand but an NDA (Non Disclosure Agreement) has to be signed first.
Remark: The FPGA library works with the basic functionalities implemented in the
firmware supplied with the SMT1026. If bitstreams other than the ones provided with the
SMT1026 are used with the FPGA library, the software will not work properly anymore. In
those circumstances Sundance will decline all responsibilities.
5.2 Host
This folder contains the source code for the host.
It's installed in the following directory: "C:/Program
Files/Sundance/SMT6026/Examples/SMT391/Host".
Remark: SMT391 can be replaced by the number of the board you are interested in.
Source code
The source code is similar for all the supported FPGA-only modules:
123456-
Open the FPGA library.
Reset the board and TIM.
Configure the FPGA.
Configure the ADCs/DACs.
Start the acquisition on the ADCs or trigger the DACs.
Save data to file (ADCs).
Tip: Change the value of the #define directives at the beginning of the program to
change the parameters. Don't forget to recompile!
5.3 Output
This folder contains the executable application.
It's installed in the following directory: "C:/Program
Files/Sundance/SMT6026/Examples/SMT391/Output".
Remark: SMT391 can be replaced by the number of the board you are interested in.
This executable is a very simple console application aimed to show the basic use of the
SMT1026 libraries. But more complicated and flexible user interfaces can be developed
using the functionalities of the SMT1026 libraries. (See Configure FPGA-only module).
