Some of the Asus
TV-Box's versions are shipped with an infrared remote control. If
you have this piece of hardware, this page is for you. The GNU/Linux
system provides a generic remote control support interface, namely LIRC (Linux Infrared Remote Control).
Using this interface your remote control isn't limited to control a TV
application only, but can start arbitrary applications, move your
mouse cursor on screen... anything you can think of.
Get your remote control working
Currently we support the PCF8574 chip which is located somewhere
within the Asus TV-Box (not in the remote control itself). This chip
is an I/O expander with an I2C interface. The chip provides 8
input/output channels, channel 1 is connected to the receiving IR
controller. We are interested to learn whether your setup is
similar. Let us know!
To get started, you need to download lirc-0.6.6.tar.gz
from the LIRC project. Then get the latest
Apply the patch:
/usr/src/lirc-0.6.6$ patch -p0 < lirc.diff
After this you can configure, build and install the lirc package.
/usr/src/lirc-0.6.6$ ./configure --with-driver=tvbox OR
/usr/src/lirc-0.6.6$ ./configure --with-driver=breakoutbox
/usr/src/lirc-0.6.6# make install
This will install a remote control server, some kernel modules, a
client library and a global configuration file (/etc/lircd.conf) which is tailored to the use of
an Asus TV-Box with remote.
Now you are ready to load the kernel modules and start the remote
# modprobe lirc_dev
# modprobe lirc_i2c
Your syslog (usually /var/log/messages or
/var/log/syslog) should tell you whether
your remote control has been detected or not.
The events (button press/release) delivered by your remote control are
now provided through a global interface: the lircd daemon. Each
application which wants to map these event to actions must communicate
with this daemon via a well defined interface (a network protocol
connection) or access the character device file /dev/lirc directly.
Most applications (like XawTV) provide
their own configuration file format. Here follows a list of downloadable
configurations which were created by some users of RivaTV. We thank all of you
for contributing, and more contributions are always welcome!
Future LIRC support
The maintainers of the LIRC project have applied our patches after the
lirc-0.6.6 release cycle (right now already in CVS). Thus it may be
possible that you can use the lirc package out of the box without
patching. We will update this page to reflect the latest developments.
