Library Version Selection in MPLAB® Code Configurator (MCC)
The Versions [MCC] tab for MPLAB® Code Configurator (MCC) shows up near the Project-Dashboard tab in the lower left corner of the MPLAB X IDE screen. The Versions [MCC] tab provides information about the versions of the component groups that make up MCC. These component groups are called libraries. Over time, multiple versions of the libraries may be available. In the Versions area, MCC can be configured to use a specific version of a library for the current MCC project.
The green check mark shows the library version being used in the project. The gray dots show optional libraries that can be loaded. Some have already been downloaded to your computer and some need to be downloaded in order to use.
Right-click on the library in question (Version 1.55) and a window will appear with a Mark For Load option. Select Mark for Load. The library will be highlighted in bold text and the Load Selected Libraries button will appear.
Click on the Load Selected Libraries button. The green check mark will switch to the selected library which will be used in any future code generation by MCC within the project.
