All sample display drivers included with the Platform Builder use the GPE classes. Although the GPE classes are optional, using them greatly facilitates the process of writing display drivers. If you use the GPE classes, you need only provide the new code that is necessary to make your display hardware operate correctly and perform acceleration.
The GPE classes require that your display hardware use a linear-frame buffer; that is, the display's memory must lie in a contiguous memory range. Modifying the GPE classes to use a non-contiguous frame buffer would require significant effort.
To create a display driver based on the GPE classes
For more information about GPE classes and methods, see the Microsoft Windows CE API Reference.
