MS-Tech MC-1200 Remote

Remote from the MS-Tech MC-1200 case.

How to set up in Linux:

UDev rule

First you have to create an own udev rule to ensure, that your device nodes are always the same.

We get the physical address from /proc/bus/input/devices:

cat /proc/bus/input/devices

the output is something like this:

...

I: Bus=0003 Vendor=04b4 Product=0101 Version=0100
N: Name="Cypress Cypress USB Keyboard / PS2 Mouse"
P: Phys=usb-0000:00:06.0-3/input0
S: Sysfs=/devices/pci0000:00/0000:00:06.0/usb4/4-3/4-3:1.0/input/input4
U: Uniq=
H: Handlers=kbd event4 
B: EV=120013
B: KEY=800000 0 e0b0ffdf 1cfffff ffffffff fffffffe
B: MSC=10
B: LED=1f

I: Bus=0003 Vendor=04b4 Product=0101 Version=0100
N: Name="Cypress Cypress USB Keyboard / PS2 Mouse"
P: Phys=usb-0000:00:06.0-3/input1
S: Sysfs=/devices/pci0000:00/0000:00:06.0/usb4/4-3/4-3:1.1/input/input5
U: Uniq=
H: Handlers=kbd mouse1 event5 
B: EV=17
B: KEY=70000 0 2010000 3978 d840d000 1e0000 0 0 0
B: REL=103
B: MSC=10  

...

What we need are the values behind Phys=. In my case usb-0000:00:06.0-3/input0 and usb-0000:00:06.0-3/input1.

Now we write a new rules file for udev:

sudo nano /etc/udev/rules.d/10-irremote.rules

and put the following content in:

SUBSYSTEM=="input",ATTRS{phys}=="usb-0000:00:06.0-3/input0",SYMLINK="input/irremote0"
SUBSYSTEM=="input",ATTRS{phys}=="usb-0000:00:06.0-3/input1",SYMLINK="input/irremote1"

Now restart udev and trigger a new discovery:

sudo restart udev
sudo udevadm trigger

Under /dev/input should now be two more symlinks; irremote0 and irremote1:

ls /dev/input

Inputlirc installation

First you have to install inputlirc and lirc:

sudo apt-get update
sudo apt-get install inputlirc lirc

Then you need to configure it properly:

sudo nano /etc/default/inputlirc

and put the following content in:

EVENTS="/dev/input/irremote0 /dev/input/irremote1"
OPTIONS="-g -m0 -c -d /dev/lircd"

(The location of lircd is different per distro/version that I've tried, for Ubuntu 10.04 it's /dev/lircd)

The entries unter EVENTS are the devices we created via udev. The OPTION entries mean the following:

-g	Grabs the input from the devices, specified under EVENTS, so that no other application interferes with it.
-m 0	By default, all keycodes below 88 are filtered out. This setting ensures, that all keycodes are captured
-c	Because some of the keys on the remote are mapped to keys with modifiers, this option maps this codes to single events.

Now restart inputlirc

sudo /etc/init.d/inputlirc restart

You can now test the remote via 'irw':

irw

This is some sample output from irw when pressing buttons:

14 0 CTRL_SHIFT_KEY_P irremote0
a4 0 KEY_LEFT irremote0
a4 0 KEY_UP irremote0
a6 0 KEY_VOLUMEUP irremote1

Configuration XBMC

The last thing you need to do is let XBMC know to what buttons to respond. This is done via the Lircmap.xml:

sudo nano ~/.xbmc/userdata/Lircmap.xml

and put the following content in:

  <lircmap>
      <remote device="irremote0">
  	  <play>CTRL_SHIFT_KEY_P</play>
          <pause>CTRL_KEY_P</pause>     
          <stop>CTRL_SHIFT_KEY_S</stop> 
          <forward>CTRL_SHIFT_KEY_F</forward>
          <reverse>CTRL_SHIFT_KEY_B</reverse>
          <skipplus>CTRL_KEY_F</skipplus>
          <skipminus>CTRL_KEY_B</skipminus>
          <left>KEY_LEFT</left>
          <right>KEY_RIGHT</right>
          <up>KEY_UP</up>
          <down>KEY_DOWN</down>
          <select>KEY_ENTER</select>
          <pageplus>KEY_PAGEUP</pageplus>
          <pageminus>KEY_PAGEDOWN</pageminus>
          <one>KEY_1</one>
          <two>KEY_2</two>
          <three>KEY_3</three>

          <eight>KEY_8</eight>
          <nine>KEY_9</nine>
          <zero>KEY_0</zero>
          <hash>SHIFT_KEY_3</hash>
          <star>KEY_KPASTERISK</star>
          <clear>KEY_DELETE</clear>

          <info>CTRL_KEY_G</info>
          <title>KEY_COMPOSE</title>
          <back>KEY_BACKSPACE</back>
          <display>ALT_META_KEY_ENTER</display>
          <start></start>
          <mytv>CTRL_SHIFT_KEY_T</mytv>
          <mymusic>CTRL_KEY_M</mymusic>
          <mypictures>CTRL_KEY_I</mypictures>
          <myvideo>CTRL_KEY_E</myvideo>
      </remote>
      <remote device="irremote1">
          <power>KEY_POWER</power>
          <volumeplus>KEY_VOLUMEUP</volumeplus>
          <volumeminus>KEY_VOLUMEDOWN</volumeminus>
          <mute>KEY_MIN_INTERESTING</mute>
      </remote>
</lircmap>

Mapping

I mapped most buttons correctly however the following is different:

Display = Start
Title = Mouse icon (top right from navigation)
Menu = Zoom
Info = Guide
