Hi R-Devel, I've been working on an oscilloscope project using an Arduino microcontroller board. I found that it's quite easy to get realtime updates, e.g. 30+ frames per second, if I read data from the board in a little Rcpp library. I have to use dev.hold() and dev.flush() to keep the plot from flickering, which restricts me to the "ca...

Anybody sucessfully got stable 1000Hz clock without Digium harware and kernel 2.6? We need to consult some peoples how to clock asterisk stable with exactly 1000 Hz without much kernel/drives patching/tweaking. Some test results we made so far: 2.6 with digium card - stable 1000 Hz. 2.6 with ztdummy - uses RTC and the clock is 1024, not 1000. 2.6 with some Realtime kernel patch - provides stable

I was curious what R packages, or indeed any other applications, exist to plot streamed data from arbitrary data generators. It need not be publication quality plotting but it should be easy to use like an oscilloscope. I was working on something called datascope that I am using for 1D finite difference monitoring and recently interfaced it to freefem. I also created an R package. If there is any interest in something like this I guess I could put it up somewhere when it is more usable or if you can suggest som...

...me work which I did using it) on Wine, mostly it works well, but: - When I close it, it enters an Access Violation/"Internal Error" loop. - Can't see text in some controls. For an example, check this image: http://img14.imageshack.us/img14/2707/75952076.png The controls in the 'Oscilloscope' window were supposed to show values. Any ideas? Since this is an old app, I tried to set Windows version to Win98 but it didn't help at all. This is the latest version of Wine on x86_64 Arch.

OPTAscope was produced by Parallax in 2002, but has been discontinued. It's a USB PC Oscilloscope. I used WINE to install it OK, but can't get hardware connected. Using Ubuntu 8.10. Here is how a normal windows install goes. Install software, plug in hardware, "New Hardware found", then go to Device Manager and find port the device assigned. In my case, it was port 3. Go back to O...

Should I worry about this? should I measure input voltage? (I suppose I'd need more than multimeter readings.

...In fact, I'm not even sure that these are indeed the right devices for the job. Could someone who is familiar with either of these devices tell me if they will fit the bill? And if possible, which of these has more useful features as telephone line test equipment? I'm handy with an oscilloscope, function generator, VOM, etc. Will I be able to drive either of these?

...tor". On my other desktop CentOS-5.2 system I have the same thing. However, one one system the icon gives me a real time (ok 5 sec intervals) display of cpu load as cyan and white bar graphs . On the other system the same application gives me a static, sickly green and yellow, display of an oscilloscope. How do I get the dynamic version of the icon? I have checked and both systems are running the same version of the applicvation from the same location. /usr/bin/gnome-system-monitor --version = 2.16.0 2. On the same two systems, the first (the one with the dynamic display) has entries on the syst...

Hi All. Yesterday I was installing Centos 5.5 to my web server, and it looks like the main hard drive has gone AWOL. Fedora 12 put the file system into r/o mode. The drive is an Hitachi, still under warranty. There are bad sectors on it, and running the Hitachi DFT tool confirms this. Also I cannot repair the bad sectors. Would this be caused by a faulty I/O chip, or is it safe to say

Hi, I am interested in nouveau tv-out support. I read http://nouveau.freedesktop.org/wiki/TestersWanted and make nvclock dump with working tv-out on nvidia drivers. xorg.conf and nvclock output are in attachments. I have free saturday evening every week, so feel free to instruct me, I like to help) Also I have some expirience in C and generic knowledge about xorg video drivers, so you may ask

Thought I would post this experience to the list so it's archived for posterity... My company is deploying Asterisk-based PBX's to all of our branch offices. Each office has 2 analog Voice lines and a fax line. We didn't want to go to the expense of using TDM400's in the servers (which run asterisk and Hylafax) so we opted for 2 X100P cards in each box. So far they have

Hi, Can anyone shed some light on this: My PC's are on a separate power circuit. Each PC has its own UPS. I have an old Honda generator. When the power goes out, I fire up the generator. However, the UPS's still run on battery. If I connect the PC directly to the socket and bypass the UPS, the PC works. I was told by a UPS supplier, that the power output from the generator was

...to find a well-connected network that rents out a few of the better-known SIP testing tools to beat on Asterisk installations in remote places for short periods of time. But this has always been the case... test gear is a small market, and expensive. Just look at the MSRP of new high-end HP Oscilloscopes if you want to get a picture of price-gouging.

Hello, I resolved my echo issue using grandstream/estara etc etc sip phones and wcfxo interfaces from digium. I swapped out my via kt400 based msi kt4vl motherboard for an asus p4pe? i845? based motherboard and the echo has completly gone away along with aggressive suppressor option in the makefile. I hope this helps others. Brian J. Schrock Anistone Technologies, LLC 6926 Avery Rd. Dublin, OH
