The MPLAB Harmony Help provided in Portable Document Format (PDF) provides many useful features. By default, PDF bookmarks should be visible when opening the file. If PDF bookmarks are not visible, click the PDF Bookmark icon, which is located near the top of the left navigation pane or by selecting View > Show/Hide > Navigation Panes > Bookmarks. 

The MPLAB Harmony PDF files are located in the ./doc subfolder of the package it documents. For example, documentation on the MPLAB Harmony 3 Configurator is found at ./mhc/doc/help_mhc.pdf and documentation on the MPLAB Harmony Graphics Library is found at ./gfx/doc/help_harmony_gfx.pdf. 

To make full use of the PDF features, it is recommended that Adobe products be used to view the documentation (see Note). 

Help on how to use the PDF features is available through your copy of Acrobat (or Acrobat Reader) by clicking Help in the main menu.

Note:

The MPLAB Harmony Help PDF files can be viewed using a PDF viewer or reader that is compatible with Adobe PDF Version 7.0 or later.
