[Gumstix-users] Video capture application

[Alexandre P. N. <al...@om...>]

Hi there,

I understand that pxa27x to be used on next-gen gumstix does video cap
natively.

However I'm considering doing analog video capture with current gumstix,
and went to this tiny thing:

http://www.semiconductors.philips.com/acrobat_download/datasheets/SAA7113H_2.pdf

I have a usb video cap device which is built with it (and a usb-specific
chip which manages the above chip, plus does video encoding).

Looking at it i've noticed that building a circuit with the SAA7113 is
quite simple: it requires a crystal, 2 wires for programmint it through
i2c, it outputs video through a 8-bit bus, plus some standard filtering
stuff (capacitors, etc) and analog inputs.

Besides that, I already found a (WIP) linux driver for SAA7113.

So my main doubt is: How to connect it's 8bit bus to gumstix? I
considered putting it on a buffer and them throwing it direct at bus
data lines (on the 92-pin header), but I have no idea how to do it; I
never done it before. How do I address that question?

I think due to the relatively high data rate that would be my best option...

Someone else thinks it is worth the shot? Thoughs?

Thanks in advance!
