Hi there,

These two patches - 'dvb-usb-ids-v2-rtl2832-fc0012.patch' and
'rtl28xxu-v2-rtl2832-fc0012.patch' adds nine devices based on FC0012
tuner, altogether eleven.
Gianluca, please inform forum fellows to test&reply.
Zdenek, fermio - there is a note on
http://wiki.zeratul.org/doku.php?id=linux:v4l:realtek:start at
"Other DVB-T Sticks" regarding 'af4d:a803' device.
Is it based on RTL2832 with FC0012 tuner?

Julian, Thomas, Antii
cheers mates!
;)

Hi poma,
I have a 0BDA:2838 (Easycap EZTV646) and a 0BDA:2832 (no name 20x20mm
mini DVB-T stick) and both are based on the E4000 tuner, which is not
supported in the kernel at the moment.
I have no idea if there are sticks with the same USB PID and the fc0012
tuner.

Regards,
Gianluca

OK, second one - no name device is "Realtek RTL2832U reference design"**.

First one:
Once upon a time there was a "EasyCAP"…
"After while crocodile!"
…and "EzCAP" was born.

Conclusion:
At least two devices share same vid/pid with different tuners - fc0012

That's it. Opening the device enclosure, I can read this on the PCB:
"EzTV668 1.0"
and it looks identical to the picture posted there.

This is not a big problem: the rtl2832 driver should read the tuner type
from an internal register and load the proper module (or exit with an
error message if the tuner is unsupported).

Very nice. So we should ask Harald Welte if he is willing to have his
driver merged in the kernel.

Just for reference, the "no name device" I bought on ebay is exactly
this one:

http://i01.i.aliimg.com/photo/v0/513925059/Mini_notebook_USB_DVB_T_Stick_receiver.jpg

Tuner: E4000
USB PID: 0BDA:2832

It is listed as "Unikoo UK001T (P160)" on the RTL SDR compatibility list:

Thanks for clarifying!
rtl28xxu.c:
…
* Probe used tuner. We need to know used tuner before demod attach
* since there is some demod params needed to set according to tuner.

/* check FC0012 ID register; reg=00 val=a1 */

I am currently finishing up the work at the demod driver and will
probably send a new version to the list tomorrow.

As I don't own a device with a different tuner than the fc0012 I will
include an error message about the unsupported tuner and print its
type. So It is easier to get the information about the tuners.

Right now I am writing the signal_strength callback and stumbled upon
the following problem:
The signal strength is read from the fc0012 tuner (only for fc0012).
How should the driver implement this situation. Is there a callback I
could implement within the tuner or should I just read the tuner
registers from the demodulator?

Regards
Thomas

Nice! I will try to review it on Monday...
I looked quickly your old patch last week and tuner driver was done by
Hans-Frieder Vogt. I think he should send tuner patch first and then your
rtl2832 applied top of that.

Sounds good.

Demod should report signal strength, normally based IF AGC. But that
estimation is very poor, tuner could report it more accurate.

On optimal situation you should implement demod callback for signal
strength and if there is tuner callback then override demod callback in
order to get better reports. IMHO that override should be done in DVB-USB
driver, in that case dvb-usb-rtl2832u. So when you attach rtl2832u just
after that override demod callback with tuner.

Antti
