Telecomandi
Terratec Cinercy T2 
La mia scheda digitale terrestre è dotata di un telecomando. Normalmente i telecomandi vengono identificati dal kernel come periferiche di input (/class/input/input*).
Il numero di input non è detto sia sempre lo stesso, potrebbe cambiare con un sucessivo riavvio del pc.
Dato che però il telecomando non è quasi mai una tastiera standard è necessario dargli un nome ben chiaro ed univoco e controllarlo per mezzo di Lirc.
Per fare questo creerò una regola udev.
Prima di tutto vediamo come esso viene identificato dal kernel:
dmesg
input: TerraTec/qanu USB2.0 Highspeed DVB-T Receiver remote control as /class/input/input3
Ecco la regola:
KERNEL=="event[0-9]*", SYSFS{../name}=="TerraTec/qanu USB2.0 Highspeed DVB-T Receiver remote control", NAME="input/terrateccinergyt2"
che scriverò in un file chiamato 003-TerraTecGmbH.rules e lo collocherò in /etc/udev/rules.d. Infine riavvierò il pc. In questo modo quel medesimo telecomando verrà sempre associato al nome input/terrateccinergyt2.
fatto questo apt-get install lirc dopodiché sistemiamo i file di lirc come segue:
/etc/lirc/hardware.conf
# /etc/lirc/hardware.conf
#
# Arguments which will be used when launching lircd
LIRCD_ARGS=""
#Don't start lircmd even if there seems to be a good config file
#START_LIRCMD=false
#Don't start irexec, even if a good config file seems to exist.
#START_IREXEC=false
#Try to load appropriate kernel modules
LOAD_MODULES=true
# Run "lircd --driver=help" for a list of supported drivers.
DRIVER="dev/input"
# If DEVICE is set to /dev/lirc and udev is in use /dev/lirc0 will be
# automatically used instead
DEVICE="/dev/input/terrateccinergyt2"
MODULES=""
# Default configuration files for your hardware if any
LIRCD_CONF=""
LIRCMD_CONF=""
/etc/lirc/lircd.conf (questo file vale solo per il mio telecomando)

Inseriamo poi nella cartella /home/mythtv/.mythtv/ il file con le corrisoindenze. Permetterà a MythTV ed a Mplyer di essere controllati con il telecomando:
