Remote Control Mini-FAQ (Rev 0.4.0, 2007-10-06 En)
==================================================
1. Which hardware is supported?
----------------------------
Configurations which have been reported to work:
card type driver connector IR protocol notes
---------------------------------------------------------------------
Activy 300 RCMM
DVB-S 1.x dvb-ttpci J2 RC5/RCMM 1
DVB-S 1.x dvb-ttpci CI module RC5/RCMM 1
DVB-S 2.x dvb-ttpci ir connector RC5/RCMM 1,2
DVB-S 2.x dvb-ttpci CI module RC5/RCMM 1,2
Nova-CI budget-ci ir connector RC5
[1] All full-featured cards support RC5 and RCMM.
For RC5 you need a RC5-capable IR receiver.
For RCMM you need a RCMM-capable IR receiver.
[2] The receivers shipped with rev 2.x cards support RC5.
Other '/dev/input/eventX'-based devices will most probably work,
if the event device is specified using the '-i' parameter.
If supported by udev, an input device can also be selected by pci slot.
See README for an example.
Please report if you have a working configuration not listed here. Thx.
-------------------------------------------------------------------------------
2. It does not work. What should I do?
-----------------------------------
2.1 All card types
--------------
Please verify that...
- the remote control really works. Check the batteries!
- the plug of the remote control receiver is connected properly.
(This is the most common problem with rev 2.x full-featured cards!)
- Use the latest version of the remote control plugin.
2.2 Full-featured cards
-------------------
2.2.1 The remote control does not work, if a CI is connected
------------------------------------------------------
Whenever a CI is connected, the on-board connector will be disabled!
On some CIs there is a jumper to select whether the receiver of the CI
or the receiver of the FF-card should be used. RTFM.
If not, use the integrated receiver of the CI,
or connect the receiver to the ir connector of the CI.
-------------------------------------------------------------------------------
3. Testing - Debugging - Troubleshooting
-------------------------------------
3.1 Identifying the correct event device
------------------------------------
Check the output of 'cat /proc/bus/input/devices'.
For example (full-featured card on /dev/input/event2):
...
I: Bus=0001 Vendor=13c2 Product=0000 Version=0002
N: Name="DVB on-card IR receiver"
P: Phys=pci-0000:00:0c.0/ir0
S: Sysfs=/class/input/input4
U: Uniq=
H: Handlers=kbd event2
B: EV=100013
B: KEY=1 ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff fffffffe
B: MSC=18
...
'DVB on-card IR receiver' identifies the receiver of the full-featured card.
'event2' is the device the remote plugin has to use (in this example).
3.2 Check the system log (/var/log/messages, dmesg, logread etc.)
-------------------------------------------------------------
The remote plugin must use the device identified in 3.1.
For example:
...
Jul 27 07:04:29 orion vdr: [4032] remote: using '/dev/input/event2'
Jul 27 07:04:29 orion vdr: [4032] remote-event2: autorepeat supported
Jul 27 07:04:29 orion vdr: [4032] remote-event2: exclusive access granted
...
If it does not use the correct device, specify the device
using the '-i' parameter.
If supported by udev, an input device can also be selected by pci slot.
See README for an example.
3.3 Enabling ir debugging in the driver
-----------------------------------
3.3.1 full-featured cards - dvb-ttpci driver
Type
echo 16 > /sys/module/dvb_ttpci/parameters/debug
3.3.2 budget card - budget-ci driver
Type
echo 1 > /sys/module/budget_ci/parameters/ir_debug
3.4 What is the expected behavior of evtest?
----------------------------------------
You should see something like this:
evtest /dev/input/event2
Input driver version is 1.0.0
Input device ID: bus 0x1 vendor 0x13c2 product 0x0 version 0x2
Input device name: "DVB on-card IR receiver"
Supported events:
Event type 0 (Reset)
Event code 0 (Reset)
Event code 1 (Key)
Event code 4 (?)
Event code 20 (Repeat)
Event type 1 (Key)
Event code 1 (Esc)
Event code 2 (1)
Event code 3 (2)
Event code 4 (3)
...
Testing ... (interrupt to exit)
Event: time 1047342384.790038, type 1 (Key), code 402 (ChannelUp), value 1
Event: time 1047342385.290630, type 1 (Key), code 402 (ChannelUp), value 0
...
'DVB on-card IR receiver' indicates the receiver of the full-featured card.
'Event:' lines are the result of pressing a key on the remote control.
To get 'Event' lines:
- vdr must be stopped.
- A keymap must have been loaded.
3.5 Loading user-defined keymaps
----------------------------
For full-featured cards a user-defined keymap may be loaded using
av7110_loadkeys from the dvb-apps package.
3.5.1 Examples:
- RC5, not inverted, keymap 'hauppauge.rc5':
av7110_loadkeys hauppauge.rc5 > /proc/av7110_ir
- RC5, inverted, keymap 'hauppauge.rc5':
av7110_loadkeys -i hauppauge.rc5 > /proc/av7110_ir
- RCMM, not inverted, keymap 'activy.rcmm'
av7110_loadkeys activy.rcmm > /proc/av7110_ir
- RCMM, inverted, keymap 'activy.rcmm'
av7110_loadkeys -i activy.rcmm > /proc/av7110_ir
3.5.2 How do I have to modify 'runvdr' to load the keymap?
Have a look at the script 'runvdr.remote' in sub-directory 'misc'.
