Re: inputlirc: zeroconf LIRC daemon using Linux input event devices

Thanks for the great little app, I found it with Synaptic from Ubuntu 8.04 when I was just about to pull my hair out trying to get lirc to work with Mythtv.  At last irw and input-events will work for me, (though not irrecord) but I'm not quite there yet.

I'm trying to get a Twinhan DVB remote to work properly. It shows up fine:

chris@PC-Linux:~$ lsusb
...
Bus 001 Device 003: ID 6253:0100 TwinHan Technology Co., Ltd Ir reciver f. remote control
Bus 001 Device 001: ID 0000:0000

and here:

/dev/input/event2
  bustype : BUS_USB
  vendor  : 0x6253
  product : 0x100
  version : 272
  name    : "Twinhan Tech Remote Control"
  phys    : "usb-0000:00:10.0-1/input0"
  uniq    : "1111111"
  bits ev : EV_SYN EV_KEY EV_MSC EV_LED EV_REP

/dev/input/event3
  bustype : BUS_USB
  vendor  : 0x6253
  product : 0x100
  version : 272
  name    : "Twinhan Tech Remote Control"
  phys    : "usb-0000:00:10.0-1/input1"
  uniq    : "1111111"
  bits ev : EV_SYN EV_KEY EV_REL EV_MSC

And some keys have worked fine from the begining with no adjustment whatever:  Enter, Exit, the number keys etc.  But the main keys I need to control Myth are Guide and the up and down arrow keys, and I can't make them work for the life of me.

irw shows them like this when I press Guide, Up, Down: (the "e" is from the "Guide" keypress)

e68 0 KEY_PAGEUP event2
^[[5~6d 0 KEY_PAGEDOWN event2
^[[6~

And input-event like this:

11:26:16.594274: EV_MSC code=4 value=458760
11:26:16.594291: EV_KEY KEY_E pressed
11:26:16.594294: EV_SYN code=0 value=0

11:26:19.753853: EV_KEY KEY_PAGEDOWN released
11:26:19.753856: EV_SYN code=0 value=0

But when I go to edit my lircrc file, I can only get certain keys to work to open the guide, and "Guide" is not one of them.  If I map the Myth command "m" to the "Stop" button or the "Up" keys, which irw says are KEY_TAB and KEY_HOME, it works fine.  But if I map it to the "Guide" button, which input-events says is KEY_E(or to e), it doesn't work and that key does what it always did, which is to bring up the Channel Editor.  Remapping the Up and Down keys does not stop them from performing the PageUp and PageDown functions either

I've stripped my lircrc down to nothing to try to diagnose this, but no joy yet.  When I start mythfrontend I can see it pointing the correct lircrc file.

I can't understand why changes to that file work for some keys and not others.

Hello,

I have some remote controls that are handled by the USB HID driver and
the AT keyboard driver. These are hard to get working with LIRC. Even
though recent versions of LIRC can read /dev/input/eventX devices, you
still need to use irrecord to painstakingly create a suitable
configuration file. However, the kernel's input layer already assigns
appropriate symbolic names to multimedia keys. To make life easy, I have
written a small daemon that acts like a LIRC daemon, but only processes
/dev/input/eventX files and translates events directly to useful
symbolic names, without any further configuration necessary. I have
tested this with a few keyboards with multimedia keys, an USB remote
control dongle that acts like a HID, and another remote control that is
handled by the AT keyboard driver.

You can download the software from the following subversion repository:

http://svn.sliepen.eu.org/inputlirc/trunk/

You need to have /usr/include/linux/input.h present. To compile and run:

make
./inputlircd /dev/input/event*

All LIRC clients should work with inputlircd. Use irw or input-events
from the input-utils package to find out the names of the buttons, and
write your .lircrc accordingly.

Comments are welcome.
