This tutorial provides the following workflow to show you how to use many
of the functions in the links. By performing the steps provided, you work
through many of the operations yourself. The tutorial follows the general
task flow fo r d ev eloping digital signal proce ssing programs through testing
with the links for RTDX.
Within this set o f tasks, numbers 1, 2, and 4 are fundamental to all
development projects. Wheneve r yo u work with MATLAB software and
objects for RTD X, you perform the functions and tasks outlined and prese nte d
in this tutorial. The differences lie in Task 3. Task 3 is the most important for
using E mbe dded IDE Link CC to develop your processing system.
1 Create an RTDX link to your desired processor and load the program to
the processor.
All projects begin this way. Without the links you cannot load y our
executable to the processor.
2 Configure channels to communicate with the processor.
