So far I only see LIRCD project that make the kernel support such device but I'm not sure if this project is the best choice since it's not part of mainline kernels. And there are certainly good reasons which I'm not aware of. Another possibility is to make the remote controle device an input device. But I see several flaws: - The IR receiver on my board can't be use as a transmitter any more - All scancodes are embedded in the kernel. Do you think it's still the way to go despite the 2 points raised above ? Thanks ! -- Francis ^ permalink raw reply [flat|nested] 9+ messages in thread

It might be, but I'm not 100% convinced either. -- Vojtech Pavlik Director SuSE Labs ^ permalink raw reply [flat|nested] 9+ messages in thread

It would still limit the IR ability to sending/receiving "just" keypresses. You may want to send and receive more (arbitrary data) over an IR dongle attached to the machine. -- Vojtech Pavlik Director SuSE Labs ^ permalink raw reply [flat|nested] 9+ messages in thread

The device I actually have, an infrared remote control, seems simple enough to use the input device model. I have a wheel on it but I think I can make it work too...

I should have said 'input events'. -- Vojtech Pavlik Director SuSE Labs ^ permalink raw reply [flat|nested] 9+ messages in thread

My IR receiver and remote also do mouse events. The Imon Pad. So yes such devices exist. -- Len Sorensen ^ permalink raw reply [flat|nested] 9+ messages in thread
