SciTech SNAP Graphics IES Demos for On Time RTOS-32

SciTech SNAP Graphics IES for On Time RTOS-32 is a scalable graphics solution for embedded systems with support for about 200 chipsets. The SciTech SNAP SDK contains everything required to develop applications using the powerful SNAP architecture. More information on these products is available on SciTech's Web site http://www.scitechsoft.com.

The SciTech demos downloadable below can be executed using a full On Time RTOS-32 release or the On Time RTOS-32 Evaluation Kit.

GATest is a display controller test for setting various display mode resolutions and refresh rates. The supported features include multi-head, TV, and LCD panel output options for the detected display hardware, gamma color correction, VESA DPMS power management and DDC monitor communications, zooming and panning within virtual framebuffer, 3D animation via an OpenGL compatible API, and support for stereoscopic shutter glasses.

MGLDemo is a series of demos of the MGL library for SNAP graphics, exposing accelerator functionality for the detected display hardware. It shows 2D drawing functions for lines, rectangles, and bitblts. High level support for bitmap operations including fonts, cursors, and icons is demonstrated.

MVisDemo shows a similar series of drawing functions using the MGL library for SNAP graphics and MegaVision GUI library. It features a C++ event-handling framework for managing desktop, menus, dialogs, and controls. The program can switch display resolutions and font sizes dynamically.

The demos have been configured to use the RTTarget-32 RAM file system to enable all demos to run without RTFiles-32 and hard disks. However, one consequence is that the drivers for all supported chipsets (200+) have to be downloaded with the first demo. Real applications utilizing a hard disk can store these drivers on the disk to avoid the extra download time.

To build and run the demos with a full On Time RTOS-32 license, download file mgldemos.zip (5.2MB). For the On Time RTOS-32 Evaluation Kit, use file mgldemose.zip (5.2MB). Expand the archive in an empty directory. In Windows, open one of the Borland or Microsoft command line demos of On Time RTOS-32 (e.g. the "Hello" demo). Change into the directory containing the MGL demos and execute make (Borland) of nmake (Microsoft) to build the demos. Install the generated Monitor on the target and then use RTRun to download and run each demo. Since the SNAP graphics library can set graphics modes at run-time, a text mode Monitor can be used.
