Fixed. - Decimation_below should be small. There's no need to change many points in the median filter if we're moving slow. In this way we will filter more noise. - Now we deliver 2X input events -- 1 each 5 milliseconds. (side effect of the previous two changes) - We should omit the last point before the UP event but I think this belongs to user-space. I'm programming a tslib filter ("skip") and if it doesn't work will I'll send a patch later to skip the last point in the driver. Signed-off-by: Nelson Castillo <nelsoneci@gmail.com>
