Post subject:  IR on Hauppauge Nexus-S/Technotrend Premium S2300 (SOLVED)
Hi all,

After about 9 months of playing around with VDR I've decided to install a knoppmyth again, the features are simply better imho

But I've seem to be stuck on getting my remote to work.. (ok so this feature is supported better on VDR, but just this one :D )

I am working with a Technotrend Premium S2300 but the card is identical to a Hauppauge Nexus S, so I mention this so others could benefit from this info. I am working though with an original Hauppauge 'silver remote' that came with a Hauppauge Nexus S card (I have both cards it's in another system now)

Some additional info:
Code:
root@mythtv:~# dmesg |grep DVB
DVB: registering new adapter (Technotrend/Hauppauge WinTV Nexus-S rev2.3)

the name of the remote (inside of battery clip):

A415
OH/S 1-3

I've tried setting up lirc throug lirc-reconfig, and I chose the 'silver remote' but it gives me a PVR-350 remote

Code:
root@mythtv:~# head -n 5 /etc/lirc/lircd.conf
# /etc/lircd.conf
#
#
# brand:   Hauppauge                    lirc.conf
# model no. of remote control:  PVR-350
root@mythtv:~#


through some googling I have found following interesting sites:

http://gentoo-wiki.com/HOWTO_Setup_LIRC_for_MythTV#Specially_for_av7110_.28Hauppauge_Nexus-s.29_cards
http://readlist.com/lists/mythtv.org/mythtv-users/0/3050.html

which lead me to av7110_loadkeys

http://www.vdr-wiki.de/wiki/index.php/Dvb-apps_av7110_loadkeys

So after issuing following command:

Code:
av7110_loadkeys /usr/share/doc/dvb-utils/examples/hauppauge.rc5 > /proc/av7110_ir


I am able to view remote keypresses (the 'Event: time' entries on the bottom)

Code:
root@mythtv:~# evtest /dev/input/event2

Event: time 1200664313.897459, type 0 (Reset), code 0 (Reset), value 0


so this works, but now I'm not sure on how to get this working in myth.

Since it's an input device, should I load it like a keyboard? I've tried disabling lirc too, and used av7110_loadkeys '-d' (default keymap) as well, but I can't seem to make it work

any help greatly appreciated

EDIT: ok after some reasoning, I think the last missing piece might be to ad the inputdevice in xorg.conf (since it acts like a keyboard) but can't seem to find any immediate info on that..

EDIT 2:
Adding it to xorg.conf would be a perfect solution, but one needs to write an xkb driver for that (out of my league)

found this though:
http://www.linuxtv.org/v4lwiki/index.php/Remote_controllers
so the modules loaded by lirc are wrong. I'll start testing this now and report back.

EDIT 3:

so i followed the guide in the link above, and was able to perform an irrecord.
I thought 'sweet, nearly there' but the generated lircd.conf is not really what it should look like (check the codes)

Code:

Ok, now what?? Ah, at least /var/log/messages is giving me some output now..

the button I pressed when receiving a value of 20 is the same as I pressed when getting the output from /var/log/messages: I pressed 'up'

being one of the ten kinds of people that know binary (some pun intended :roll: ) and hex too for that matter, I know 0x14 is 20 in decimal so I guess I'll have to edit the file manualy. Don't know why irrecord messed up like that.. ah maybe I screwed it up somewhere..

aargh, what is wrong? I've seen enough hex for one day.. Maybe some of you could shed some light on this..

I thought the codes where not valid cause of padding (eg 0x0000000000000001 instead of 0x01)
but changing that was fruitless as well.

been looking at following guide, but it's in german and my german is more then a little rusty:

One day later, been reading a lot about 'linux input layer'
playing with tools like keyfuzz and input-utils I believe I'm not going to waste more time on lirc.

the input device is working well, but mythtv doesn't seem to be listening to that device:

when I switch to terminal and press buttons on my remote characters appear on screen (in terminal) The chars are wrong (the mapping seems wrong)
when in an X11 terminal though, the kepresses are showing up correctly!

So basicly, mythtv is listening to the wrong device, now, how do I fix that?

any help greatly appreciated,
bonarez

Ok getting better results now

mythtv catches keypresses, but sadly not all..

I have installed 'inputlirc' whicht is in the apt repository.

It's a zeroconf 'fake' lircd, that catches events from the 'linux input layer' and lets lirc clients connect.

now just getting all the keys right. I'm still not sure on how to configure it properly, I do not know if any lirc config files are still to be used, In any case I will try to get it to work with keyfuzz, since it will work in any other x11 program then..

Guess I need to do a lot of scancode/keycode mapping now..

The Hauppauge Nova-T's IR comes up as an input device as well. Lirc will work with it direct, you just need to tell it to use the dev/input driver. Heres my hardware.conf:

Code:
LIRCD_ARGS=""
START_LIRCMD=false
LOAD_MODULES=false
DRIVER="dev/input"
DEVICE="/dev/input/event2"
MODULES="lirc_dev lirc_i2c"

thanks for the help, but I think I can get it to work 'without' any use of lirc.

I've already found a way to map my keys, it's just that I'm having trouble finding the right scancode/keykode for some keys. (space char to be exact)

the remote works for most of the keys though, without using lirc / inputlirc (eg: apt-get remove inputlircd && /etc/init.d/lirc stop) still works

I'll still need some time to get them all working, then I'll make a small howto on it.

the configuration is much simpler then lirc, and it works with any device that supports the linux input layer (think bluetooth, joysticks, etc). I really believe this is the way to go.

edit: this issue is to be considered solved
allright, found a way to get the scancodes nice and easy, using tools installed by default, you can expect a howto on this next few days..

I'm allmost there, it's just that some keys used by myth are giving me troubles, like escape

this is the scancode/keycode I get from the keyboard
Code:
root@mythtv:/home/bonarez# showkey
kb mode was RAW

press any key (program terminates after 10s of last keypress)...
0x01 0x81
0x01 0x81


this is my temporary rc5 file, (not the one for the hauppauge remote, decided to get it to work with the remote that was bundled with my card, but in the end it doesn't matter does it?)
Code:
0x0c KEY_0
0x03 KEY_1
0x04 KEY_2
0x05 KEY_3
0x06 KEY_4
0x07 KEY_5
0x08 KEY_6
0x09 KEY_7
0x0a KEY_8
0x0b KEY_9

0x0d KEY_UP
0x10 KEY_LEFT
0x11 KEY_DOWN
0x0e KEY_RIGHT

0x0f KEY_ENTER
0x09 KEY_M

0x02 KEY_P
0x18 KEY_C
0x12 KEY_I

loading it up through
Code:
root@mythtv:/home/bonarez# av7110_loadkeys /root/test.rc5 > /proc/av7110_ir

and it all works,exept of course the escape key, if I add that key (0x13 KEY_ESC) to my rc5 file, it won't load:
Code:
root@mythtv:/home/bonarez# av7110_loadkeys /root/test.rc5 > /proc/av7110_ir

ERROR: could not parse '/root/test.rc5'


ah too late and too loaded for this now, /me is sleepy.. tomorrow
