2.2 Importing the Examples into Code Composer Studio

There are six CCS project examples attached as collateral to this document. Project collateral discussed in this document can be downloaded from the following URL: https://www.ti.com/lit/zip/spma083. The projects can be unzipped into a folder or kept in the zip file. Both formats can be imported to the CCS.

  1. To import the project into CCS, first select “File” -> ”Import”.
