196 Example FTXL Applications
Overview of the Example Applications
The FTXL Developer’s Kit includes two example applications: the simple
example and a dynamic interface example. The simple example application is a
very simple application that simulates a voltage amplifier device. This device
receives an input voltage value, multiplies the value by 2, and returns the new
output value. The dynamic interface example application includes the same
functionality as the simple example application, but adds the ability to change
the SNVT types for two of the network variables and the ability to add (and
modify and delete) dynamic network variables.
The following sections describe the two example applications, including their
design, how to build them in the Nios II IDE, how to load them into the Nios II
processor in the FPGA device on the DBC2C20 development board, and how to
run them.
Example Application Files
The two FTXL example applications are provided as project templates for the
Nios IDE: the FTXL Simple project and the FTXL Dynamic Interface project.
Each project template includes only a few files and cannot be compiled or run as
is; you must run the LonTalk Interface Developer utility to generate and copy the
required files for the project.
The FTXL Simple project includes the files listed in Table 55. They are installed
to the [ Altera ]\nios2eds\examples\software\FTXL_Simple directory.
