Testing Algorithms and Data from a File
This chapter shows the process for creating and testing a simple algorithm
and introduces additional Code Composer Studio features.
In this chapter, you create a program that performs basic signal processing.
You expand on this example in the following two chapters.
You create and test a simple algorithm using data stored in a file on your PC.
You also use Probe Points, graphs, animation, and GEL files with Code
Composer Studio.
