Hello Dominik,
Thanks for that link it looks very useful. It is strange that there is nothing on the DirectFB site| The LCD panel will be accessed through a parallel interface direct from the micro. So there is no intention to use the graphics core. Looking at some of the gfxdriver under DirectFB e.g. davinci_gxfdriver.c it open the /dev/fb0 device. I thought that /dev/fb0 would have to be opened. Again I have not seen clear instructions as to what will need to be coded.

Only this: http://elinux.org/images/6/6c/Elce2007_directfb_gfx.pdf Eventually it helps... Do you have a full documentation of the graphic core inside of your ARM processor? In my opinion, if you have a working gfx driver, Directfb won`t use /dev/fb0...

I have looked over some DirectFB documentation, but it is not exactly clear how I go about this. I think I have to create a GFX driver. However, there does not seem to be a clear set of instruction as to what functions need to be coded to allow DirectFb to work with it. Also what is the relationship with the GFX driver, framebuffer driver (/dev/fb0) and the Dot Matrix display. Do I need to create a new FrameBuffer driver for the Dot Matrix display? Any pointers or development guidelines would be appreciated.
