QUOTE (v_pan @ Dec 14 2008, 04:53 AM)
i will use a PIC microcontrolle that supports USB2.0 hardware.i will make software of USB protocal .so, output from PIC will be a usb cable (not rs232 to usb converter) and i 'll plug it to one of my usb2.0 port
on my computer
in that case, will LABVIEW recognise this PORT as serial(COM4 for example) or usb?
can i increase speed that way?
thanks for answer!!
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.

hello everybody..i made a project based on microcontroller and communicate with 232.
my baud rate is at 115200bps and proved to be very poor for what i want to do.
i'm thinking to change my communication to usb2.0 (microcontroller support )
my question is ..
if i do this ,do i have to change my program on labview?
i mean ..
now i select COM1 to communicate with micro
after change this
the only thing i have to do is to change COM1 to COM4 for example?
and increase baud rate
or i have to do more things on program>?
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.

hii have one query on ivison labview toolkit
i have downloaded the trial version of it and iam using it and now
i want to combine two avi files into one using that toolkit in that the functionalites used can overwrite but cannot join them that my problem
i will explain in detail
in the software i have function which can write avi to disk for that i have given one input file and i have given another file as output both have some data now i thought of joining the avi but its overwriting that it now that function name is ivision_openavisession.vi
so plz any one can help how to combine two avi files into one avi file using labview
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.

Tried the s/w from Hytek automation, it can take pictures, but I am not able to control anything else. (i.e. no zoom, ISO or focus settings)any suggestions?
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.

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?

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.

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.

Thank you Irene. While in English it loses the poetry of the original, it is nice to know what sentiments are being expressed. I'm surprised, with all of the effort that China put into trying to use the Olympics to promote itself, that this song did not get more visibility. Very nice.
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.

What exactly is the purpose of Chinese captioning on a Chinese Video? It's a very good video, but I wish that I could know the words.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.

BTW, since I was gone... which country won the olympics? (Shameless attempt to come back to the original topic)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?

Agreed!I don't have access to fancy graphics software but PowerPoint and Paint let me do this. (My old PC was crying durring these edits!
) This includes the top eight contributors Sorry Rolf, I told him to draw ten.)
There is also the option that I get my artist to re-do the image but doing characatures of the avatars (Tomi, your avatar will be a challenge).
Maybe a collage of the rest of the avatars in the background?
Could these images be combined with the Volcano image somehow?
I'll gladly supply the original (huge) BMP's to anyone that has better tools for this job.
I'm open to whatever the community thinks.
Just trying to help.

Can I use this picture as avatar? I wonder how this will fit into the supermen's picture.

i have a problem with DAQ when i shut down the computer a 5 volts are on the digital output port thi means all the relays are on ?can any body help me?/
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.

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.

Is it possible to acquire images from our tv card instead of cameras?i am trying to test the outputs of a dvbs (satellite receiver),
1] we will feed the tv card inputs (composite,s-video,TV ) by our receiver under test's output...
2] the receiver plays a constant stream for example (color bar)
2] we will acquire images from tv card
3] and compare these images with the correct files at the pc (jpeg files)

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.

"4. Why does..." My personal theory on that question is .... (deleted because its even too out-rageous even for the LAVA Lounge)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:

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.

Are anyone from San Francisco watching the olympic torch run? I know some of you are from San Francisco.
I am watching the Beijing 2008 Olympic torch run in San Francisco life in Internet right now. Hope it is a smooth run unlike what happened in Paris and London.
It seems some western media is using Tibet issue to against Beijing 2008 Olympic, obvious lies from some western media angered and hurt the NORMAL chinese people outside and inside the China. Especially German "Spiegel" magazine.
By the way, I am not a chinese spy like what German "Spiegel" magazine had on it's cover page, they said all chinese students are spy, Oh ja, what a narrow mind... It brought me to a memory over 10 years ago, sitting in front of TV in an appartment in Berlin in Germany, watching the report regarding the Chinese won a Olympic gold medal, the way that TV guy said, made the blood pressure went high, and I remembered that I wanted to write a letter to that TV station to protest...Human right is not true human right if that only means to "your people". Well, that said, I have to say there are some very wise German people, I hope this post does not make anybody mad, but I feel the responsibility to speak out.
Well, good thing is that my blood pressure level is normal since I live in Canada and I really appreciate the generality of American people that I know, I learn a lot from them. I think American people are different from American politics.
Wish the "world peace"

How to achieve a fast PWM
in Hardware
Posted
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:
