Hi,
I created some patches to support the AVerMedia AVerTV DVB-T 771 card. The
drivers aren't finished yet (mt352 doesn't support all ioctls, analog
settings for the bt878 are wrong, I did only a short test with dvbsnoop).
The patches are available here:
Hi,
thx, Wolfgang Joost, the patches seem to work, i have made some small
cleanups on the bttv-cards.c.
I already send corrected data to bytesex.org:

ok, i have tested now with mythtv, it works perfectly, very special thanks

drivers. i think some cleanups maybe should be done for the drivers and

Hi,
Here's a patch against CVS for the mt352 driver. The TPS_GIVEN fields
had the wrong shifts (consistently off by 1) so it wouldn't tune for

Hi,
Currently we are aware that you use the Connexant
cx23883 as the PCI interface and a Samsung tuner
Which tuner do they use? Is the mt352 part of the tuner? If yes, its probably
the same tuner AVerMedia used for their 771-card...

Hi,
btw: does anybody of you has an idea how we might make use of the
automatic channel scan functionality of the MT352 under Linux, how we
might need to extend the LinuxDVB API?
I would add two ioctls:
- FE_START_SCAN with the lowest and highest frequency to scan as paramters.

Hi,
I would add two ioctls:
- FE_START_SCAN with the lowest and highest frequency to scan as
paramters. - FE_CONTINUE_SCAN
After the FE_START_SCAN the kernel-thread monitors the fe-status and send
an event if the fe locks or an event when the fe finished scanning.

Hi Jolse,
I know that the frequency is correct because i noted the frequencies for
the channels in windows.
Did you check the other paramters, too? AFAIK wrong settings for the bandwidth
cannot be corrected automaticaly.
the read of register 0x00 returns the same as the read of register
Hi,
if i add:
r = mt352_read_register (i2c, 0x7f);
before:
r = mt352_read_register (i2c, 0x00);
the read of register 0x00 returns the same as the read of register 0x7f!
And it appears that the snr values from above are actually the value of
register 0x03!
Hello Jolse,
Doesn't the driver set the tuner bandwidth based on the frequency?
No, it doesn't. It switches to the right wave band. I mean the 4th parameter
in tzap's channels.conf
Here's a sample of what I get while tzap is running, this is also with a
read of 0x7f at the end of

note to self: read also the mailing list archive from 2004-06, not
only 2004-05. It works now. I replaced rt352.c with this version:

Hi Dirk,
thanks for the diff.
The important parts are in set_parameters. One diff is a != instead of
a = and the return value is not EINVAL. The invalid return breaks it,

channel-parameters.

Hi,
I will try again the next days. BTW, what is FE_SLEEP doing (ok,
sleep, I see that, but what is the effect)?
It disables most of the internal functions of the mt352. Result: less heat and
less power consumption.
Wolfram
Hello,
sounds good. Does it sleep when I unload the driver again? I could
only load it when needed.
No, but of course you can change this.
Wolfram
Hi,
The problem isn't the sleep itself, the problem is that in the CVS code

Hi,
it works on boards with hardware i2c enabled. Changing the I2C_M_NOSTART
to 0, as you did, is the right thing to do here.
Ahh, OK.
Attached is a patch against CVS that makes software I2C work, as well as
implementing the second policy.

I had a closer look to your patch:
