Re: touch screen driving me nuts!
if we look at the pic, the top 4 red lines are deviated upwards with the one closest to the centre being the most deviated, and the lowest 4 red lines are deviated downwards with the one closest to the centre being the most deviated again.. it does certainly look like a weird pressure from somewhere to me... was it like this when you got the device?, i'm no expert in this area but i think some excess pressure has been applied on the unit's screen or something before... from the middle i guess.. or something dropped and the shape of the screen got bent very slightly maybe.. what do you guys think?

That is, if I use for example the matchbox onscreen keyboard and tap a key multiple times, maybe 1 in 10 taps or so is recognized 1-2 millimeters off (usually below where I touched). And if I start numptyphysics and just shortly touch the same spot again and again, I sometimes get little 1-2mm strokes instead of just a dot. -- Tobias PGP: http://9ac7e0bc.uguu.de このメールは十割再利用されたビットで作られています。 ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I have tried that. The biggest problem is that the area in the middle of the screen where the line breaks, is just plain dead, so I can't actually tap on last cross-hair. Try that, and if it still as wonky, I would say the digitizer is broken. Not knowing anything about touch screens, is the digitizer something that I might be able to replace or is it some surface mount thing that I would be doing good to see much less desolder. -stacy ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

touch screen driving me nuts!
My wife would argue that it is more of a putt than a drive... however, my touchscreen is having some serious issues. To demonstrate the problem, I created a 480x640 image with seven straight lines running across the screen, I installed mtpaint on my freerunner and attempted to trace the (blue) reference lines in red (I used a straight edge, so this isn't just my normal inability to draw a straight line freehand). I made three passes over each line to show the repeatability. The result is here: http://www.millions.ca/~stacy/neoFreeRunner/touchscreen.png with window decoration etc, the top line is not visible so there are no trace lines for it. Trying to dial a phone number or use the on screen keyboard is an exercise in frustration. Anybody have any suggestions for what the problem might be or what else I could do to try and debug this? -stacy ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
