7 Library Source and Projects

This section describes how to import and rebuild the libraries and provides a description of each API function. Each Code Composer Studio library project includes configuration information for the Configurable Logic Block (CLB). To learn how to modify the CLB's configuration, see the CLB Tool User's Guide.

Note: Some APIs work with Pulse Train Inputs (PTI) and others with Pulse Train Outputs (PTO). For simplicity, the examples, libraries, and directory structure make use of the suffix "pto" to identify content belonging to this library.
