Directory Structure

The Microchip Graphics Library installation follows the standard directory structure for all Microchip library solutions. Installing the library will give the following structure:

One of the demo subdirectories (example: Graphics or Combo) may become "Your Applications Directory" that will contain your application source code. You can add code and modules here that will use and interact with the library. The library specific folders are the following:

  • The Microchip folder will contain the library components.
  • The Help sub-folder under Microchip folder will contain this document (Graphics Library Help.chm file).
  • The Graphics sub-folder under the Microchip folder is where the C files, documentation and utilities are located.
    • Inside this Graphics sub-folder are the directories for the Drivers, Documents, GDD, Images and bin directories. It will also contain the directory for the Image Decoders source files.
    • The GDD (Graphics Display Designer) directory contains the GDD project template. Use this to start projects using the Graphics Display Designer.
    • The bin directory contains the Graphics Resource Converter utility and External Memory Programmer both implemented in java.
  • The Include sub-folder under the Microchip folder will contain common header files to all Microchip library solutions.
  • Another Graphics directory is included in the Include sub folder. This will hold the Graphics Library header files as well as the header files for the Image Decoders.
  • The Board Support Package folder will contain hardware specific drivers that are common to the Microchip Demo Boards (such as Explorer 16, display panels or PICtail™ Plus Daughter Boards).

All subdirectories and files under the Microchip directory should not be modified. In case your project will use more than one Microchip library solution, this directory will contain all the library files you install. Thus, it is important to maintain the files in this directory. The Microchip Solutions directory may become your "MyProjects" directory that will contain all your projects using the different Microchip solutions.

Demo Projects

The Microchip Graphics Library documentation has several components that covers installation, customization and usage of the library. Several demo projects are included in the installation to help you get started. Detailed information on each demo project is available from the "Getting Started" help file located in each of the demo folders. 

 

Schematics

The library installation also includes schematics of currently supported controllers and glass. These can be found in the ../<install directory>/Microchip/Graphics/Documents/Schematics directory.

Images

The library allows displaying 1bpp, 4bpp, 8bpp, 16bpp and 24bpp images. They can be located in program flash space or external memory. To convert the bitmap format file (BMP extension) or JPEG format file into source C file containing data array for internal memory or Intel hex file for external memory the Graphics Resource Converterincluded in the library installation can be used. Refer to the utility help file for details on usage. 

 

Fonts

The library operates with 8-bit character encoded strings. It covers languages defined in IS0 8859 standards. East Asian and any other languages support is available for UNICODE encoded fonts. Font can be stored in internal flash as an array in const section (this limits font image size by 32Kbytes) or can be located in external memory. To convert the font file into source C file containing data array for internal memory or Intel hex file for external memory the Graphics Resource Converter utility can be used. The utility allows importing raster font files (FNT extension) or true font files (TTF extension). Refer to the help built in the utility for details. Raster font files can be extracted from MS Windows bitmap font package file (FNT extension) or converted from true type font file (TTF extension) with a third party font editor. One such freeware editor Fony is available at http://hukka.furtopia.org/. Another example is http://fontforge.sourceforge.net

The utility also allows reducing the generated fonts to include only the characters that the application will use. This can be done by using font filtering. Please refer to application note "AN1182: Fonts in the Microchip Graphics Library" from the "Training and Support" section of the Microchip graphics website for details of implementing reduced fonts. 

 

How to use the API Documentation

This help file includes the API description of the library. The way the API is structured is similar to the library layers.

  1. The Device Driver Layer presents all the API included to initialize and use the display controller and the glass. This section also contains information on how to add new Device Driver.
  2. The Graphics Primitive Layer is a hardware independent layer that contains the API for basic rendering functions. Use this section to render basic shapes like lines, rectangles, filled circle etc.
  3. The Graphics Object Layer contains the API specific to each Widget type. Use this section to create and manage Widgets as well as pages or screens of different Widgets. Messaging and rendering of Widgets are also included in this section.
