Dev help

2009-12-24 Thread sijones2006
Hi All,

I'm just wondering if someone can point me in the direction of maybe 
either some documents or a good driver code to look at to understand 
how to write the drivers for cards etc.

As some might have seen as playing with the terratec cinergy 2400i 
which has an old driver and am gonna have a play and see if i can get 
it working.

Not sure if my coding would be good enough to submit to yourselves at 
the moment, but if there is a document to read, as current I dont 
understand how the PCI-e bridge loads and then loads the demod module 
and tuner and how it all links together...

So any documents and maybe an example modules that loads a bridge / 
demod then tuner so i can understand would be great.

Cheers for any help.

Cinergy 2400i - Micronas APB 7202A Open Sourced!

2009-12-17 Thread sijones2006
Hi,

I know this has been brought up a number of times on Myth and other 
lists but there is now a change of circumstances.

The PCI-e bridge (MICRONAS APB 7202A) has now an open source driver. 
It is available here git://projects.vdr-developer.org/mediapointer-dvb-
s2.git 
could this now be pulled into the main V4L source? as it has been 
brought upto date with the current DVB tree.

The demodulators MICRONAS DRX 3975D seem to have a driver in the 
current tree.

My only issue is now the 

* Tuner #1: THOMSON DTT 75202A (with RF connector)
* Tuner #2: THOMSON DTT 75207 (with pin RF input)

I can't seem to be able to find a tuner that will work out of the git 
source I have pulled.

both the ngene and modulator modules I have to modprobe in, if i 
reboot they dont get reloaded, am currently running Unbuntu 9.10, any 
help would be appreciated! 

If the source for the PCI-e bridge can be brought into current then it 
would seem a number of cards would be able to work.

I think someone has already tried some work on another card which uses 
this bridge as wel

The driver cannot be pulled in 'as is' for various reasons, but we 
are
currently preparing the driver to make it ready for inclusion into 
the
master HG repository/kernel.

Is there a repository that I can use to build / test this? and is the 
tuner supported as well??

I am not sure about the git repo but the original release included
drivers for the cards on the market (dual DVBS2 by DigitalDevices, 
Terratec Cinergy and an ATSC card) and all prototype cards.
Since most of the driver was written in 2005 it is a little 
behind regarding kernel API changes and available in-kernel drivers 
for 
tuners and demods. But you should be able to get hints from it
to adapt it to the current kernel/DVB repo. 


Thanks for your reply, when I looked through the original source code 
I can't see a driver for the tuner THOMSON DTT 75202A, is included in 
the code but named something else?

When I load the ngene module, should it say anything more than the 
copyright notice in the kernel logs?
