RC5 frames are repeated every 113.8 ms (64*T, T=16/9 ms). The key-release timeout in cx88-input.c is 120 ms. I can't locate the repeat timer value in the sources now, but I think it was less than 100 ms. In your patch, you have defined IR_MIN_REPEAT_PERIOD to 133, so it should not be a problem. However, you also have IR_MIN_REPEAT_DELAY equal to 250 ms, which means that the first repeated RC5 frame will not result in any event. > > I would very much like to have a direct correspondence between repeated RC5 > > frames and key-repeat events, but I could not figure out how to do this in > > cx88-input.c > > cx88? That'd be the newer Nova-T, not the Nova-T :-) Well, Nova-T 90002 REV C176, then. :-) > I've posted a set of patches to the v4l list which should be of some help; > you should have a look at budget-ci after applying the patches, which you can > also get from here: > <URL:http://ymbj/progs/linux/dvb-ir-20060129.patch.tar.gz> Hmm, I may be mistaken, but it looks to me as if your patches try to do the same thing for older cards as the new Nova-T driver already does. What I would really like to have is to map every RC5 frame either to a key-press or to a key-repeat, and a timer for generating key-release events. Does any existing driver (or patch) do that? Marko
