Other Parts Discussed in Thread: TFP410

Hi,

I'd like to use the BeagleBone DVI-D cape to display graphics using StarterWare.

http://download.tigal.com/beagle/BeagleBone-DVI-D-01-srm.pdf

(I've tested the board and it works with WEC7 and Android)

The cape takes the LCD drive and converts it to DVI-D using the TFP410.

The output resolution of the cape is 1024x768 and its 16pp.

I've imported the evmAM335x raster demo project and am modifying the settings in the rasterDisplay.c file to try and drive the cape.

The monitor sees some sort of signal with the code I have and suggests changing the resolution to 1680x1050 -60 Hz, so I figure its getting close.

Does anyone know what settings I would need to change for the Starterware API raster.c functions?:

RasterClkConfig(), RasterDMAConfig() , RasterModeConfig(), RasterTiming2Configure() , etc.

Thanks for any help.

Craig,

Were you ever able to get this to work? I am also trying to get the BeagleBone with DVI-D cape running (in SYS/BIOS) with not much success so far. It sounds like the raster examples from the Sitara Industrial SDK might help me?

Thanks,

Noel

Hi Craiq

Have you succeeded with maintaining resolution 1680x1050 ?

I think TFP410 can support maximum resolution upto 1600x1200. And i am little confused with -60Hz can you explain it little more ?

Please come with your feedback.

Thanks
