That description was in linux, but I tried again toady in the OFW test and had very similar results. I was able to reproduce it almost immediately on power on and it seems to be related to the pressure. Light pressure behaves normally, heavy pressure causes the problem. I had trouble reproducing diagonal jumps in OFW today but got a few small ones, I didn't re-test in linux. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I was also able to make it jump diagonally, mostly at 45 degrees. It was most noticeable while rolling the finger where large jumps often occur. Watching carefully reveals the pointer also doesn't quite follow the finger in normal motion too, sometimes following an arc when the finger is moving straight, other times just being slightly disconcerting. In normal motion the problem is often subtle and I might not have noticed it if it wasn't obvious while rolling. The problem took a little while to show up this evening -- everything seemed normal for 5 or 10 minutes or so. All my testing so far has been on battery power (battery life seems excellent by the way) I haven't played much with the membrane keyboard unit today, but will give it a finger rolling workout tomorrow. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I don't know enough about Turtle Blocks to comment, but if an application such as Turtle Blocks tries to read the sensor, it will probably block for as long as it takes for the transaction to complete ... roughly 33 milliseconds. I am getting 60mS per read in Turtle Blocks from print time repeat 100 acceleration print time Tony ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

On an XO-1.75 B1, I get between 17.07 and 18.22 reads per second in /runin/runin-accelerometer with os40. That would be 59mS to 55mS. One imagines that Turtle Blocks may be doing more than just reading. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hi Testing a 1.75 with the HS 'clicky' keyboard Speak is a bit clicky. The clicks occur in the same places on the same text. Repeat some text: ctrl C ctrl V ctrl V and the same word is clicky, eg 'the quick brown fox' the word 'quick' is noticably more clicky. Power on fanfare sounds louder and tinnier. Maybe a peak or resonance in the treble? I have noticed on the 1.5 and 1.75 mouse that if my finger is too far forward on the button it overhangs the pad and gives a jumpy cursor. The pad is not sure which finger to track. Tony On Mon, 2011-08-22 at 21:15 +1000, James Cameron wrote: In testing the speakers we found the sound to be scratchy like there are buffer issues. That's interesting. More please? Speak is the only activity we've which produces sound and works. The sound is full of clicks. Also the turn on tune sounds different to how I remember the XO 1.5 but I haven't done a side by side test. There is something less pleasing about the XO 1.75, but I can't describe it. Our clicky keyboard unit has some kind of mouse problem. Sometimes, the mouse jumps, especially when you are holding a button. This was especially a problem with turtle blocks where you have to hold down the mouse button and do very fine control to snap things together. Rolling your finger to move very slowly sometimes causes the mouse to jump several block heights, rolling it back would cause it go back, but actually landing on where you need to go is impossible. Release everything and starting again lets you carry on until next time it starts jumping. I haven't yet tried to pin down the intermittent nature (like say a fraction of the area is faulty) and I haven't noticed any patterns except that it seems worse while holding down a button (with either the same or a different hand). The membrane keyboard model does not seem to have this problem. Do you have any advice for further diagnosis? Is this a known failure mode of the XO-1.5 touch pad (I'm assuming the keyboard half is the same in the 1.5 and the 1.75?)? We have some XO-1.5 prototypes with wich we could swap the touch pad and see if the problem follows the touchpad or stays with the 1.75. Is that useful? ___ Testing mailing list test...@lists.laptop.org http://lists.laptop.org/listinfo/testing _ This mail has been virus scanned by Australia On Line see http://www.australiaonline.net.au/mailscanning ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
