The difference in read rate is not the board (A3 vs B1) but a code change to temporarily slow down the access of the TWSI bus the accelerometer is on due to a temporary hardware constraint. -Saadia On Mon, Aug 29, 2011 at 12:10 PM, Bert Freudenberg wrote: > > On 25.08.2011, at 07:47, James Cameron wrote: > > > On Thu, Aug 25, 2011 at 03:22:06PM +1000, fors...@ozonline.com.au wrote: > >>> 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 > > > > On an XO-1.73 A3, I saw 25 reads per second, which would have been 40mS > > per read. > > > > On an XO-1.75 B1, I get between 17.07 and 18.22 reads per second in > > /runin/runin-accelerometer with os40.

The heat spreader on the XO-1.75 has four attachment points. Removing and replacing it multiple times shouldn't cause any problems, just try to avoid getting the heat conducting gunk over the SoC dirty.

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.

The device measurement range, in the default configuration, is a minimum of plus or minus 2.0 gravities, and typically plus or minus 2.3 gravities. The device sensitivity, in the default configuration, is between 15 and 21 milligravities per binary digit, which would be between 0.147 and 0.206 metres per second squared. At the moment, in the XO-1.75 B1, we have the sample rate set to the default of 100 Hz, but the CPU can only read at about 30 Hz due to an electrical design fault (#11041). On the A3 we did have it set higher, and it was possible to read data at about 900 Hz, which meant you got repeat samples. Then, we were able to configure it for 400 Hz and read it at that rate. Have a look at /runin/runin-accelerometer for some of the code involved. At that rate I saw noise in the signal that was consistent with ambient sound. My theory is that sound in the vicinity of the laptop, especially sound at a frequency close to resonance, would cause vibration of the circuit board, and this would be picked up by the sensor. One could imagine it to be a low frequency microphone in three dimensions, with an unusual frequency response. ;-) > I'm not really familiar enough with Turtle Blocks to know if the > performance I am seeing is because reading the sensor is slow or > because computing the average is.

I tried very carefully using one finger from directly above (no button pressing and no other hands nearby) and still experience the jumpy cursor problem. 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.

I must say I hadn't thought about where the noise might be coming from, I merely wanted to process it out. Is it really sensitive enough to pick up normal sound (not just boom sounds!)? Going back to what I was trying to do, I was trying to make a spirit level, so I'm not interested in vibration. I'm interested in enough averaging to smooth out the noise (whatever the source) while retaining enough speed to such that the turtle moves smoothly. I'm not really familiar enough with Turtle Blocks to know if the performance I am seeing is because reading the sensor is slow or because computing the average is. I had the blocks turned off because my program was in the way of seeing what was happening and I did discover this greatly speeds things up, but updates were still slow enough to make finding the zero point difficult. I suppose exposing the raw data is good for teaching about the properties of the sensor and the real world (if it is indeed picking up small vibrations). However I suspect many applications would like some signal processing and a lot of those would like fast signal processing. If the sensor is up to it but turtle blocks itself isn't, perhaps some signal processing could be built in. Either as a separate "average n values" block, or a property of the accelerometer block? Then you can have a conversation about the sensor and signal processing without having to introduce loops and boxes? There might also be a use case for a "zero" transformation where you declare the current orientation as zero and thereafter return the offset from that. My vector math isn't quite good enough to work out how to do that, never mind express it in Turtle Blocks. I say this because the first thing I did was wonder why only one axis was near zero with the laptop sitting "flat". I quickly realized the sensor is in the screen and the screen was tilted backwards! Can you make subroutines in turtle blocks? My program was a bit unwieldy with just two loops in it. I guess I should look at the examples.

No, not just olpc.fth, also OpenFirmware looks in bootfw.zip if the laptop is secure. I've just tried this by downgrading to q4b05, then booting with X game pad key, and the result is "No signature for our key list", "Boot failed".

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.

Installed qb407 and os40: Boots. No pretty boot. Boot chime is a little 'tinny'. Connect to WPA secure access point works great. os40 brings 'Switch to Gnome' function back into form. In os36 it was putting up a file not found and reverting to a text display. Required manual reboot to get to the other desktop. As I said, works now. Connect to WPA access point on gnome works great. However, just like on previous versions, 1.0 and 1.5 included, Gnome doesn't 'remember' the last successful connection from Sugar. Not a bug - a feature :-) Yum install cheese brings in the right 2 rpms armv5tel from the repo. Nice. One still needs to do the 'modprobe mmp-camera' to get cheese to see the device, and the camera is very 'jumpy'. Cant seem to get my USB 3G modems to show up in the network manager broadband section.

Re: Re: [Testing] [OLPC New Zealand] New prototype XO-1.75s in Auckland, New Zealand
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.

Try not to remove it unless you must. On the XO-1.75 the heat budget is much cooler, so it is not as critical, but hey, you're in a hot country. The XO-1.75 heat spreader should have an additional mounting point on a limb, so make sure you screw that one down too.

http://dev.laptop.org/ticket/10528 is one such ticket, although we have two
types of touchpads in production and two alternate candidates I am aware of
(samples of which should be at Cambridge office).
I would be cautious about attempting to identify touchpads via psmouse/DMI;
three of the four samples seem to identify themselves as some variant of
"IM{Ex}PS/2 Generic" just like web browsers tend to identify themselves as
"Mozilla compatible".

Re: Re: New prototype XO-1.75s in Auckland, New Zealand
Yay!!! The 1.75 arrived today. Got it unbricked ok and installed os36 Ran Turtle art and the accelerometer works. :) You will need V114 though. Does it need the mod where you put tape on the heat spreader near the power jack? There is a thread on the heat spreader, are there any precautions to refit it ok? The mouse pad now registers clicks, can this be disabled? Needs a my settings item. Fails on restart, need then to reboot. Will keep testing Tony ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I saw the Wiki XO-1.75 page was a bit out of date, as was the XO-1.75 B1 page, but I checked and they looked reasonable at the moment. Let me know if there's any other documentation that is lacking, or flag it with a comment in the Wiki. > We now have build 36 customised Sugar 0.92.4 and firmware Q4B07 (note > that the firmware doesn't appear in the "about my computer" ... This was fixed in Sugar 0.93.2 released last Friday, but it hasn't been included in a build yet, as far as I can tell. Check it in the next build. > Not sure how the gear button could operate with the clicky keyboard as > it seems when you push it, the whole key is pressed, not just the gear > end, ... Hmm. I thought it did the same on XO-1 and XO-1.5, in that it closes the same circuit path ... and to use view source one must combine it with the fn key. So view source is effectively fn-space. > The alternative key glyphs don't work yet. Yes, please test again when #11135 and #10934 say to do so.

Yes, #11140, and I don't expect it to change, except that once #11135 and #10934 are fixed the frame key in the top right will also work. > The microphone and camera don't work yet. Yes. You will find both will work in OpenFirmware, using "test /audio" and "test /camera" respectively. But in Linux they do not. This is #10831 for the microphone, and #11129 for the camera, please test again once they say to do so. For the camera, you can test with os36 if you first load the mmp-camera kernel module. > In testing the speakers we found the sound to be scratchy like there > are buffer issues. That's interesting.

You tend to discover wireless problems well. I suspect it is something about your location. ;-) There's #11133 open looking for someone to test the wireless performance, ... I suggest comparing it against XO-1.5, and measuring bandwidth, latency, signal strength, and compatibility with access points. See if you have anyone in your team who might like to explore further, such as using iperf and other tools. Or, just see if you can get Sugar activities to collaborate reasonably well. I've not tried that yet. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

FN-SPACE is mapped to View Source, hence it doesn't matter where you click the key. I put the graphic on the left edge of the key because I a have a predilection for left-justified.

Maybe you could play with it? (It pushes X, Y, Z values to the stack: you retrieve them with 3 consecutive 'pop' blocks (found on the palette with the gear). The audio sensors do not yet work on the 1.75. Portfolio also knows about the 1.75 where it has a hidden feature: if you hit the left side of your computer, you get the next slide; right side of your computer, the previous slide. Note that Measure will launch but does not work yet. regards. -walter > > Tabitha > > ___ > Devel mailing list > Devel@lists.laptop.org > http://lists.laptop.org/listinfo/devel > > -- Walter Bender Sugar Labs http://www.sugarlabs.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
New prototype XO-1.75s in Auckland, New Zealand
We have just today received 2 of the XO-1.75 prototype B1 without touch screen. They arrived with a serial adaptor for updating the firmware. The documentation is a bit chaotic so it's hard to work out what build and firmware should be on it. We spent the first few hours testing on an old build with old firmware thinking we had updated to the latest. We now have build 36 customised Sugar 0.92.4 and firmware Q4B07 (note that the firmware doesn't appear in the "about my computer" but does appear on pressing escape during startup). One has the membrane keyboard and the other has clicky keys The clicky keys are very cramped, especially in the bottom right hand corner, and will take a while to learn to type on (though probably fine for smaller hands). Not sure how the gear button could operate with the clicky keyboard as it seems when you push it, the whole key is pressed, not just the gear end, but the shift alt v combination does bring up view source. The alternative key glyphs don't work yet. The frame key has moved from top right corner to f6 - a problem for the membrane keyboard as the key pictures don't match. The touchpad lets you tap the pad so you don't have to click with the button to select. The microphone and camera don't work yet. In testing the speakers we found the sound to be scratchy like there are buffer issues. They boot faster than the XO-1.5 but the activities don't appear to load faster, in fact lots fail to start (e.g. physics wont start). The activities that fail to start seem to need native libraries -- we see lots of missing shared object error messages in the logs. Thanks for sending us these to test. We'll watch for any testing requests as well as continuing to try things ourselves. Tabitha ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
