-infrared remote control support in video4linux drivers
-Current versions use the linux input layer to support infrared
-remote controls. I suggest to download my input layer tools
-Modules you have to load:
- saa7134 statically built in, i.e. just the driver :)
- bttv ir-kbd-gpio or ir-kbd-i2c depending on your
- card.
-ir-kbd-gpio and ir-kbd-i2c don't support all cards lirc supports
-(yet), mainly for the reason that the code of lirc_i2c and lirc_gpio
-was very confusing and I decided to basically start over from scratch.
-Feel free to contact me in case of trouble. Note that the ir-kbd-*
-modules work on 2.6.x kernels only through ...
-how it works
-The modules register the remote as keyboard within the linux input
-layer, i.e. you'll see the keys of the remote as normal key strokes
-(if CONFIG_INPUT_KEYBOARD is enabled).
-Using the event devices (CONFIG_INPUT_EVDEV) it is possible for
-applications to access the remote via /dev/input/event<n> devices.
-You might have to create the special files using "/sbin/MAKEDEV
-input". The input layer tools mentioned above use the event device.
-The input layer tools are nice for trouble shooting, i.e. to check
-whenever the input device is really present, which of the devices it
-is, check whenever pressing keys on the remote actually generates
-events and the like. You can also use the kbd utility to change the
-keymaps (2.6.x kernels only through).
-using with lircd
-The cvs version of the lircd daemon supports reading events from the
-linux input layer (via event device). The input layer tools tarball
-comes with a lircd config file.
-using without lircd
-XFree86 likely can be configured to recognise the remote keys. Once I
-simply tried to configure one of the multimedia keyboards as input
-device, which had the effect that XFree86 recognised some of the keys
-of my remote control and passed volume up/down key presses as
-XF86AudioRaiseVolume and XF86AudioLowerVolume key events to the X11
-It likely is possible to make that fly with a nice xkb config file,
-I know next to nothing about that through.
-Have fun,
- Gerd
