Preliminary working HVR-1850 IR hardware and grey Hauppauge RC-5 remote

[Andy Walls]

Steve,

I've finally have a working implementation of the the HVR-1850 IR
receiver and the grey Hauppauge RC-5 remote with in kernel (non-LIRC) IR
input to key press events.

If you feel adventurous, give it a try for testing the IR receiver:

http://www.linuxtv.org/hg/~awalls/cx23888-ir


Caveat emptor:

1. I would not recommend reviewing the code by individual change sets.
The change sets become an evolutionary mess towards the end, as I would
find a few minutes here or there to add a few lines of code. :)  I will
provide a cleaned up version, most likely some time after the LPC.

2. I need to clean up of some dead/commented out code.

3. I need to port it forward to catch up with recent changes to the
cx25840 module, cx23885 module, and IR keytable changes.  (The code
compiles and works, but I started working from a v4l-dvb clone from a
few months ago. There have been a few changes in areas I have worked.)

4. It only works for CX23888 devices right now. CX23885 devices should
be easy enough to support after cleanup and initial merge of this code.

5. I specifically did not address the RC-6(A) remote.  With the
CX2388[58] hardware, it wouldn't be hard to handle the RC-6(A) remote,
but the v4l-dvb tree is missing lots of RC-6 definitions and helper
functions.  I figured I'd rather focus on a LIRC plug-in for a
v4l_device rather than reinvent RC-6(A) inside the v4l-dvb code.


Regards,
Andy

Very nice, excellent work. Sorry, my weekend was crazy so I never managed to 
test your tree, even though I saw your email. Today and tomorrow won't be much 
better as I'll be preparing to head out to LPC.

A couple of things on my mind currently:

1. I'd like to test this asap and give you some feedback. This is a very welcome 
addition to the cx23885/25840 driver codebase. In reality this could be a week 
or so.

2. Once you have your patch-sets in order I'd like to pull those patches and do 
some HVR1850 analog encoder work. I have some small patches pending that should 
immediately allow me to start testing various aspects of analog. (Unrelated to 
your IR work but highly related to the fact you're fixed up the clocks inside 
the 25840 nicely).

3. Getting RC5 IR support on the existing HVR1800/HVR1250 would be _really_ nice 
and from the sound of it an incremental step built on the current work. I think 
from memory you only have HVR1600 and HVR1850 Hauppauge boards. Is this correct? 
I want to bring a couple of 'samples' to LPC for you.... Assuming you're 
interested. Let me know as my luggage space will be tight.

4. I'm hoping we'll sample a beer or two in Portland ;)

Hello All,

 I am new to the list. I am currently working on a dm7025 platform and
would like to know if there is a possibillity to use the 128 pid filters
on the xilleon 226. currently I see only /dev/dvb/adaptor0/demux0-3 in my
device directory - i,e; at a point in time I can use only 4 tpid filters
from the 128 available at hardware level.


Cheers,
Warm regs,
G.

Hello George,

demux0-3 represent different TS inputs. You can open each demux device
multiple times. The 128 PID filters are shared between the four devices.

Regards,
Andreas

Thanks Andreas, That answers my question. I am using a tree I checkd out 3
months ago. I used the DEMUX_SET_SOURCE API to set the ts feed to the
tuner. Is this explicity done on Linux DVB 3?

Thanks,
Warm regs,
George.

By default, all demux devices are connected to the first frontend slot
of the DM7025. You can use DMX_SET_SOURCE to connect a demux to a
specific slot.
