Screen Drivers

RTPEG-32 is shipped with six different screen drivers, all of which are implemented as classes derived from PegScreen. However, the internal class declarations are not accessible to the application. Only methods defined by the abstract base class PegScreen should be used by an application.

Each driver implements a unique function to initialize it. These functions return a pointer to the PegScreen derived calls of the respective driver or NULL, if initializing the driver fails.

The DOS utility program VESATEST.COM shipped with On Time RTOS-32 can be used to determine which drivers are suitable for a particular target computer.

The source code of all drivers is available in directory Driver\Peg. If you need additional screen drivers, please contact On Time for further information.
