Post subject:  myLCD based test programs for the USBD480

Michael has made some software for the USBD480 using the myLCD library

VLC video output plugin


"Some more not very useful demos, but demos nonetheless."


"'ScreenCap' basically streams windows or GDI objects (surfaces) directly to the display. Seems to work for everything I've tried it with including DDraw and OpenGl games, but not anything which renders to an overlay surface such as a video player. In which case can be used to render video directly to a DDraw RGB surface."


"Quake .exe's"

Some of these are seen in the screenshots here: ... index.html

Notes for the above programs:

Quake1 should be fine with the demo. Not tried with full version.
Quake2 executable tested with a full install with lastest point release.
Quake3 requires full Quake3 as the demo uses a different folder tree.
With Quake2 and 3 it's possible to add the LCD's native resolution to the internal list of supported resolutions, as can be seen with the 130x130 option, but I didn't bother.
With Quake1 the supplied batch file must be used to start.

Gears demo is functional. Try the arrow keys along with Z and Shift+Z.

Then try this:
This is just the rollercoaster demo but with a slight change to how OpenGL is setup. If it works for you then the included .dll may be used with the previous upload.

Problem isn't with displaying the data, as 'Fire' shows, its with acquiring the data through the OpenGL interface. If you modify the config.cfg file to enable the virtual display you'll see this.

The difference between glfwdemos.rar and usbd480_demos.rar is that the former creates and maintains GDI window whereas in the latter the window is closed/deleted once an OpenGL context as been acquired. Could try rendering to a BITMAP then attempt to read the pixel data via Blitblit()'ing (or whatever) as opposed to glReadPixels().

The Virtualscreen has also no output.
I think the glscreen needs to display on fordergrund.

Run the gl_boing.exe from glfwdemos and move the consolewindow over the glwindow.
The overlapped screen is not displayed on the LCD

Will I'm stumped.

Fire is working for you because it isn't OpenGL based.

Is the touch interface working or in progress ?

The Player works and if i press one of the consolekeys the touch interface displays on TFT.
But no reaktion if i touch the touchscreen. ;)
