QUOTE (Ernest Galbrun @ Dec 18 2008, 04:10 PM) I guess you want to turn PWM output into custom signals such as sine etc, then why not use a hardware based PWM output? iUSBDAQ-U120816 uses PWM outputs that exist on microcontroller itself. And this application note tells a very easy way to turn PWM into analog output with few resistors and capacitors. http://ww1.microchip.com/downloads/en/AppNotes/00538c.pdf Irene

Hello, iUSBDAQ- U120816 can output two 10bit PWM channels with frequency between 3kHZ - 333kHZ. Changing duty cycle takes about less than 8ms. There is another model iUSBDAQ - U1208LOG takes only 4ms to change duty cycle of PWM channels. Below is the link that you can take a look: www.hytekautomation.com Irene

QUOTE (v_pan @ Dec 14 2008, 04:53 AM) Well, it depends on what firmware you implemented in the hardware. If you have COM type firmware, then it is just a RS232 to USB converter. For a true USB2.0 device, you should be able to stream your data very fast. Irene

QUOTE (v_pan @ Dec 14 2008, 03:31 AM) Hello, If what you changed is just adding a RS232 to USB2.0 converter, like what you have said it shows up as COM4, then nothing on speed will improve, even though it is connected to USB port and use a USB cable, but underlying communication protocal is same, it is still RS232. To fully make use of USB protocal, you need to use a true USB device, not a simulated COM port. Regarding the LabVIEW code, yes, you only need to change COM1 to COM4 if you use a RS232 to USB converter, no other code changes needed. Irene

QUOTE (bharath_all @ Dec 13 2008, 02:09 AM) Hello, IVision LabVIEW toolkit can record from multiple video cameras into one avi file. It does not provides functions to combine two separate avi files into one file. Can you record avi files with IVision? This way you can avoid to convert after the recording. Irene

QUOTE (Prasun @ Dec 11 2008, 06:52 PM) Hello Prasun, Canon does not support control camera settings remotely. Most Nikon cameras do. So it is camera dependant. These settings are optional features with PTP protocal, so the vendors can decide if they want to provide these features for PTP or not. Irene

Looks interesting and it is not final released yet. I think some NI smart camera are dual core (ARM+DSP). I don't think NI's are based on WinCE, maybe Linux? Irene

QUOTE (crelf @ Nov 15 2008, 10:34 PM) Hi Christopher, iUSBDAQ comes with both the compiled ready to run software as well as LabVIEW examples with source code (none compiled ones) that implement all iUSBDAQ features and functionalities. To James - This is Irene from HYTEK. iUSBDAQ provides a DLL alike file for MAC (*.so file) as well as a simple testing program. If you needs more functionalies in MAC, you may need to run LabVIEW examples in MAC or do your own programming. In order to load up LabVIEW vis in MAC, you just need to link to the .so file for iUSBDAQ when LabVIEW asks you to find it. The same LabVIEW vis, examples for windows can be used for MAC. But if you don't want to do your own programming or run LabVIEW, your best choice is finding some middle ware to make window's application running under a MAC machine. Below is a link that I found: http://www.codeweavers.com/products/cxmac/ Thank you, Irene

I thought this is interesting. It seems the most capitalistic country USA is going socialism soon. Goverment is going to own lot of private properties (bailout). I listened few times when Treasury Secretary Paulson made speaches, one time he kept saying "my chinese friend", (it sounds pretty true hearted to me when he said that ). Hmm... I am wondering if he gets too much influence from his "good friend". I always admire American people's creativity and adventurism. See everything is possible... I hope there is no offensive to anybody, I thought this is a good joke. Irene

You can also check what is the webcam's color space, is it RGB or YUV or any other format. That will also affect your output image data array. You can play to select RGB format (Logitech usually always provide this format), see if results are better. Irene

QUOTE (JiMM @ Sep 9 2008, 07:16 AM) Yes, you are right, somehow this song was not broadcast here (the English captioning version is only half of the original song). Guess Chinese people are still learning how to tell the world who they are. But then, if the world dislikes it, that is because the rest of the world don't GET IT. Sorry for being a bit political recently. Irene

QUOTE (JiMM @ Sep 8 2008, 08:54 PM) I found the version with English Captioning. Although after translation words kind of becoming flat, losing some original tasting and smelling, but should still be good enough to know what they sing about.

Love this song so much.

QUOTE (normandinf @ Sep 1 2008, 10:56 PM) There are two different views here. In America, I saw US on the first in the list as US won the most total medals. In a Chinese TV in Canada, I saw China on the first in the list as China won the most Gold medals. And in Chinese internet, some people put US at first, some put China at first and I even hear the sentiment that some Chinese people like US to be the first on the list, because that make them feel most comfortable to have US as the biggest brother, still. Interesting, isn't it? Irene

QUOTE (sara @ Apr 30 2008, 04:25 AM) Shutdown computer does not mean there will be no power into your DAQ card. So the DIO will maintain it's state unless you programmatically set the DIO to low when you exit your software. Only when you power down your DAQ card (if it is USB DAQ, just unplug the USB cable), then the DIOs will go back to it's default state. Some DAQ DIOs has default to high, some to low state, depends on spec. Irene

Never played Geocacher before. But I do have one GPS, most time it works great, but sometime, she told me to turn right, then when I did as she said, she told me right the way "turn around when possible", but... so for a while I didn't know where to go. I hoped she was not as lost as I was. Irene

QUOTE (rolfk @ Apr 9 2008, 02:58 AM) Actually TV tuner card works quite a bit different from USB webcam even it supports the WDM driver. The functions for USB webcam may not just naturely work for TV tuner cards. IVision LabVIEW toolkit has functions that take care of both USB webcams as well as TV tuner cards, if the devices support WDM driver. A demo version is free to try at below link: http://www.hytekautomation.com/Products/IVision.html Irene

QUOTE (ulugun @ Apr 11 2008, 06:46 AM) Hello, You can use IVision LabVIEW toolkit to capture video from TV tuner card such as ATI all in wonder card. The TV card can be used to receive TV or as frame grabber to receive video from composite or s-video. There are vis in IVision LabVIEW toolkit that can programmatically select the video source mode (TV or composite or s-video) and audio source. Please download a demo version to try out. This is the link: http://www.hytekautomation.com/Products/IVision.html Thanks, Irene

QUOTE (Cat @ Apr 23 2008, 01:18 PM) what is goecachers? Maybe I should check google first before ask, but it is easier to ask.

Thanks again for everyone that took their time to read my posts and cared about what I have to "scream" and open their mind to provide their thoughts and views. Ben/Albert, thank you for pointing out that maybe human kinds have not changed much for 2000 year, but I think they are indeed more "civilized" in the way that at least they give you a "reason" if they want to beat you. Jason: thank you for your detailed reply to every point that I made and provided your "western" view. I am not going to take more LAVA space to discuss in details of each points here. Two things that I want to say is, I believe what you said that American people felt bad for what they had done in Iraq and felt ashame, maybe sorry, but is that enough to cover up the damages and keep the right to "try out" new things of this kind? Second, Tibet Spiritual leader Dalai Lama does not claim independancy and he supports Beijing Olympic, why should westerns be more excited to separate Tibet? I don't think there is oil in Tibet. By the way, I was curious to see what CNN has to say this morning, and I found this report (is it true?). If it is a true report, I do think Americans are indeed more "intelligent". http://www.cnn.com/2008/US/04/13/us.olympics.ap/index.html Anyway, let's come out of this politic/Tibet/Olympic field, back to the reality world. I am glad that I get a lot of smiles at the place/country where I live and I smile them all the way back. All my Canadian and American friends are still my good friends. Let's keep up doing a good job at LabVIEW world. Irene

QUOTE (neB @ Apr 10 2008, 03:50 PM) I would be interested to hear your theory if you don't mind, please send to my email. Some chinese people get so offended that they setup an anti-cnn.com website, revealing all the liars that media reports with pictures. Some western media even used picture from a movie to tell a lie. Do they think all chinese are idiot or they actually think their country people are idiot?? But I guess they indeed do foolish quite a lot of people. :thumbdown: Irene

Thanks for everyone that posted their opinion and speak out what they think. It hurts brain to think on this heavy thing, but I guess I have the responsibility to tell the world what I think, after all I have travelled quite some places in the world and see both side of the world. 1. Western likes a lot to talk about human rights and especially like to criticise China for lack of that. I agree that China has room to improve on that. But on the other hand, while country like Germany chasing down the foreigner and beat them down, make them feel like third grade human being (maybe that is the way how they make themself feel best, what a civilized group of people!) and US occupies the Iraq, how can they turn around and dress up like a human right defender and "teach" china you should do this and that. You probably don't know, in Chinese value, people disgust double moral. Even China is not doing good at human right, but they don't buy your advise either. 2. Certainly there are deep misunderstandings about China and it's people, thanks for massive western media. For many people that never travel and see the other part of world, media is certainly the only window they see the world and build up their mind. From my experience, minority nations in China such like Tibet (if you don't know, China has many different minor nations, not just Han) gets priorities in school and extra benefits and discrimination had never crossed my mind when they were my classmates, I didn't know any difference between them or others. There is a long history about Tibet being part of China, why is western so exciting and passionate to separate it from China?? Would you like to give a piece of your country land to others? Although I do hope through this incident, Chinese government has to think about what more they can do for Tibetan people and how to best handle this issue. 3. Human rights and freedom has a limit, how much do you want? Again, I agree China has to improve more, but how worse is it at all? Is it like hell like what western media has told their people (especially those never see other part of the world, they would believe it so firmly)? The answer I guess is no. My parents and my sisters are in China, they live in a comfortable harmony. The untrue report from western media actually angers more normal chinese people, the dishonest media just help them to realize that the once admired western world is actually quite "evil" and people will open their eyes and the colorful ring about western's democratic disappears. 4. Why does western want so desparately to push China to think as they think, get the same value as they do. Maybe afterall, it is still a culture thing, and western thinks they are the best, everybody else thinks differently should be cleaned out. If everybody thinks the same, same culture, what a boring world that we would have! 5. At the end, self center, individual value, distance between human beings is important in western world's value. I miss so much the close distance between human beings, the harmony and good willing between human beings, everytime I visit my parents, the warm feeling of human touch overwhelm me and I want to say, please don't try to turn chinese people into the same value as western's just because the westerns don't know or even taste the wonderful feeling of human touch. Done of my rant. Welcome critisize. Irene

QUOTE (carlover @ Mar 12 2008, 10:22 PM) Hello, with IVision LabVIEW toolkit, you can record multiple video streams from multiple USB cameras into one AVI file and you can play back later to see the multiple videos. More, you can combine the multiple video streams to different display mode, such as picture in picture, side by side etc. There are examples in IVision LabVIEW toolkit to get you started easily. Demo version is free to download. Below is the link: http://www.hytekautomation.com/Products/IVision.html Irene
