Philips datasheet : TDA8275A

I ask philips for a datasheet and they kindly (even fastly) get it to me.

I'm not sure to be authorized to put it on the mailing lists, neither in the
wiki.

So if you need it, you can ask me.

Regards,
David

Hi, Nico

yes, please :)


Just to note this: This chip is an upgrade of the TDA8274/75
on your card, it significant improved. Unfortunately it is
incompatible from the software point of view

Anyway, it would be nice if you could write a driver for it
but i don't know about cards already in production

Best Regards
Hartmut

Gives me hope for my card then! :-)

I'm getting a bit frustrated - my logs keep getting better but I was not
able to achieve sound/tuner or radio capability so far (only svideo/comp).
I'll just post another one on the thread.

Greets!

Hi, Alexander

I understand your frustration, but the situation is difficult
as long as nobody who can do the coding has such a card.
I think i could help you as soon as i knew which hardware is
on the card and how it is configured. But currently i need to
guess
I am busy at the moment but later i might be able to send you
some teat programs.

Sorry
Hartmut

Thanks Hartmut!

I am a programmer myself, I just recently "converted" from Windows to
Linux for good - I've had dual boot system over 10 years with Linux. Yet
I never really committed myself to open source completely. Now I bought
a new notebook with latest technology and *g* well I am fraid it boils
down to writing my own configs and drivers for sound, modem and tv-card.
Thats a good thing on the one hand - and on the other hand its time
consuming (learning step). Especially as I am application programmer,
I've never written a driver so far, not to speak of a driver for linux S.
I intend to get all the stuff on my notebook running - and when it comes
to that I want to understand it. I'd like to use Linux & open source for
all my private and working stuff and part with Microsoft. My (very much
unsupported system) is a perfect practice ground as a starter. As soon
as I am firm with the matter I'll be able to write patches, drivers and
tools not only for myself, but also as a contribution to the community.
For that reason I am also very interested in how - for example - the v4l
works. I have some idea just from my past experience - but I am a
"newbie" as I've said before on that matter.

Is there any literature (preferably online available) on the matter of
v4l, tv-cards, radio etc.? I'm looking for something that covers the API
basics, as well as some technical background (gpios, tuner models, i2c,
etc.) so I have some idea what I am actually doing - till now I felt
more like an field experimenter - observing and tweaking settings to a
device and learning by its responses (and obviously having bad luck with
its design).

Well then, I wish you all a nice sleep - it's again way past time here
in Austria.

Best wishes!
Alexander

After several hours trying to find ati drivers, the card is being returned
to the store.

I am looking for video capture via s-video/composite both live and time
shifted record mode, tv tuner section useless since I am out of fta, cable
area

any preferred card to use in it's replacement?

leaning toward the win tv pvr 250 card by Haupp.

ease of setup and use, stability, image+ sound quality issues.

Welcome to the club! I am an IC designer with C knowledge so be shure,
I know what you mean! My philosophy currently is: have an basic overview
and start digging into the details where its needed.

I intend to get all the stuff on my notebook running - and when it comes
to that I want to understand it. I'd like to use Linux & open source for
all my private and working stuff and part with Microsoft. My (very much
unsupported system) is a perfect practice ground as a starter. As soon

This would be good

etc.) so I have some idea what I am actually doing - till now I felt

device and learning by its responses (and obviously having bad luck with
its design).

I know that v4l and dvb API specs are on the net, look at linuxtv.org and
bytesex.org. For I2c specs i'd recommend to search the Philips web site.
But i have no recommendation on Linux driver architectures axiliary stuff
etc. If anybody has a good tip, I'd like to hear it as well.
But dealing with the media chips is hard stuff. My impression still is:
you will have a very hard time if you don't know how the ICs and the
system basically work.

But we might continue the following way: I might give you instructions
as soon as there is a bit more time and you do the rest.

Would that be ok?

Good mornig to Australia

V4L specs (both 1 and 2) are already on CVS (at doc directory). You
may check bttv library for card descriptions (and pictures). There are
some datasheets at manufacturers site (Philips, Conexant, ). Also, in
older posts, you would find references for some specific chipset specs.

Hi,
I use datasheetpro.com/index.php when I need datasheet for any component and it works very well for me. Datasheetpro is a free electronic engineering tool that enables you to locate product datasheets from hundreds of electronic component manufacturers worldwide.
Try it and I hope you will be benefited.
Good luck!
