Drive LEDs on 8-bit Digital I/O for WattsView Power Monitor

Hi could someone please help me with modifying the following LabVIEW program:
About the program:
I'm currently building a bike generator that would have the ability to power LEDs (based on whatever power is output). The LEDs would look like it's scrolling. While doing some testing, it appeared that the maximum power obtained while pedalling the bike was about 3 W. Connected to the generator is a serial power monitor called WattsView, which is a circuit that contains a loop that measures amps using the hall effect. This circuit collects data of volts and amps, sends it the software it went with onto the computer, and I am also able to view power (calculated).
On the WattsView circuit, an 8-bit Digital I/O is also included, which operates from 0 to 5 Volts DC. Below is a picture of how WattsView looks like. On the WattsView website, a free LabVIEW driver is also included. Below is also a screenshot of the program.
WattsView Website: http://wattsview.com/
I currently do not have access to LabVIEW (it's on my work computer), so I will post other screenshots later. However, below is a table of what I would like to do with the 8-Bit Digital IO Port.
Basically, I would like to have each LED turn on when it reaches +0.3 W. Currently, my idea of doing it would be to create a constant from the power indicator of the LabVIEW program. I will then use the In Range & Coerce Function to set the upper and lower limits for the power range (using the power constants).
Upper limit: 0 W
Lower limit: 2.4 W
The In Range output will then be connected to the selector terminal of the case structure. So when:
In Range Output = 1: Execute equation to turn on necessary LEDs
In Range Output = 0: Do nothing
At this point, I have no idea where to go, particularly with the case for when In Range Output = 1. I was thinking of doing a bunch of nested case structures within this case for the different ranges. However, I don't know how I would do it so that the LEDs would scroll up when power increases, and scrolls down when power decreases. Any light of this situation? Any tips or advice is greatly appreciated.
Thank you for taking the time to look at my post!

I'm still confused on how to obtain power in the correct format.
Below is a screenshot of the entire LabVIEW WattsView Driver (Block Diagram)
Circled in red is the data of volts and amps that is being collected from the WattsView circuit connected to the generator. Double clicking this icon for "4 Mat Data" opens the following Front Panel:
I opened the block diagram for this VI, and below is how it looked liked. Circuled in red, I determind this is where the output of power is, for P = V*I. Therefore, I created an indicator for the power to display the values on this VIs Front Panel.
I copied the Power indicator onto the main LabVIEW Driver Program, and below is how it now looks like:
I am unable to connect the Power indicator to the input of the Quotient and Remainder Function. This function accepts a double 64-bit, which is the data type of the Power indicator. Now I'm lost. How do I make this Power as the proper input into this function? And how would I go about inputting a constant valu of 0.3 into the second input of the function?

Hard Drive LED?

My final configuration was all leads with labels towards top of case except for POWER LED; POWER LED has label facing down toward bottom of case. Not getting them all right would impact others; for instance, not orienting the POWER LED down would make the HDD light stay constantly lit or not at all (can't remember exactly ... I had to try so many combos). The point being that a totally unrelated lead may impact the LED that your having a problem with so you may have to play around awhile to get them right.

How to install driver on a 64 bit system to access a networked printer connected to a 32 bit pc?

Did a clean install of 64 bit Windows 7 and tried to connect to Deskjet printer connected to a 32 bit Windows 7 system on home network. Said to install from Windows installation DVD but no such animal on DVD. HP error only talked about USB connection and said nothing about network. Hookup worked fine when everything was 32 bit.
This question was solved.
View Solution.

Sorry, that wasn't clear at all. I would use the 64 bit machine to go on the internet and download the latest 64 bit driver for the printer. Just run the setup on the 64 bit machine and I believe it will give you the option to search for a shared printer. You must use the 64 bit version of the printer driver on the 64 bit machine. The driver is just telling the 64 bit machine how to communicate with the printer no matter where it is.

How to Install 64-bit "Generic / Text Only" print driver on a 32-bit Windows 2003 Server?

Hi All,
In a nutshell, I need to Install the 64-bit Generic / Text Only print driver on a 32-bit Windows 2003 Server’s “Generic / Text Only 32-bit print queue.
The problem is that there is no Driver-Disk to get the drivers. I’ve been able to isolate 14 files related to the 64 bit drivers from a Windows 7 x64 computer and copy them to a temp folder on the Windows 2003 x32 server. When I try to add the 64 bit driver
to the Windows 2003 x32 server, it wants a *.inf file, which I don’t have and can’t find.
Because Microsoft will no longer support Windows XP, my client is replacing all of their Point-of-Sale Windows XP x32 systems with Windows 7 x64. They use Terminal Services (Remote Desktop) to connect to a Windows 2003 x32 server to use the POS system. The
POS software redirects LPT1 back to the local Generic / Text Only printer. This works great for XP x32.
When we use the Terminal Services POS software on the new Windows 7 x64 system, none of the labels print out because it’s redirected in 32-bit back to the local Windows 7 x64 Generic / Text Only 64-bit printer.
This will be a huge issue for me if I can’t get this to work.
Thanks in advance for any suggestions and help! -Rob

How do I connect my external hard drive with all of my digital media to my Apple TV network and make it accessable 24/7?

How do I connect my external hard drive with all of my digital media to my Apple TV network and make it accessable 24/7? I have the latest Apple TV, ipads, iPhones as well as a solid HP Windows machine all on my home network. Is there a way that I can connect my hard drive to my receiver or Apple TV directly so that the digital media is available on my network 24/7 rather than have it connected to my computer and available through Home Share which never works anyway??

Sorry it's all done through iTunes.

Dont buy a Western Digital, get a Hitachi or Seagate (Toshiba is made by Hitachi). These are the most reliable, and the HD used inside Macs.
ALL HD can be made compatible with your MAC (including a WD if you already bought same), ......they just need to be formatted for the Mac platform, format them in Disk Utility as Mac OSX extended journaled.

KT6V Hard drive led always on

My hard drive led is always on. I know I have it connected correctly as per the manual. I have 2 IDE hard drives on ide bus 1 and a cdrw and a zip drive on ide bus 2. Any help would be great.

I had that problem some days ago. It was very queer, since at booting, system didn't detect the slave HD. If I entered bios in that moment and went to detect the HD that appeard as not installed, Bios detected it without problem and then begun all booting process again and then the slave disk was detected OK. Now, if I couldn't enter Bios, at first Windows detected the HDD that wasn't detected by Bios, but some days later I found that Wind.XP didn't detect it either. Then was that the HDD led stayed on, and the slave HDD running. The solution: I changed the master/slave config. to cable detect and all went OK since then.

I install window 8 and Unfortunatly all drive format. And all drive mix, now i have only 1 DRIVE C. I want Bit locker Drive's data Back

Last sunday i install a window 8 and this window format my all drive & make it 1 drive (DRIVE C). Before all of this i have 5 drive in different size with 1 Bitlocker protect drive.
So i try data recovery software to recover my data. i got back all my data without that ( bitlocker ) protected drive.
so please guys help me how can i get back data from bitlocker protected drives.
please please help me.

Hi,
I sorry for your experience, but there is no way to recovery the data encryped by BitLocker untill now.
BitLocker is designed to make the encrypted drive unrecoverable without the required authentication. When in recovery mode, the user needs the recovery password or recovery key to unlock the encrypted drive. Therefore, we highly recommend
that you store the recovery information in AD DS or in another safe location.

10 bit colour display path for lightroom 3??

I have been following an interesting forum topic on the PS forum here about 10 bit monitor support in PS CS5.
For some background:
10 bits/pixel is becoming more prevalent with high-end displays these days (it provides 1.07 billion color possibilities instead of the 16.7 million colors available with the regular 8 bit display path). Getting a fully working 10 bit path from the app to the display appears to be more of a challenge though, but a challenge which appears to have been overcome now in PS CS5. I'm wondering if moves are afoot for Lightroom to also support the 10 bit color path??
This is my take for what you need for PS CS5 to display 10 bit colour in windows (sorry, I'm not a Mac person so couldn't comment):
Suitable graphics adaptor - Some ATI FirePro models and nVidia Quadro models support 10 bit color (cheapest is nVidia Quadro FX 580) - the availability/use of the displayport interface is most often the tell tale pointer as to whether the adaptor supports this. Only more recent driver packs provide 10bit API support for apps to utilise, so latest drivers are often required.
Displayport connection between graphics adaptor and monitor (DVI only supports 8 bit color)
A monitor which supports 10bit color - (High end NEC models (PA241W/PA271W models and new Spectraview Reference models in UK) now support this as does the HP DreamColor plus some Eizo and Lacie models to mention a few)
Enable 10bit color support in the Graphics adaptor control panel - this option generally only appears when all of the above is in place, and when enabled, provides the display path via OpenGL, for apps to utilise if they are coded for such (this option is known as 'Enable 10-bit pixel format support' for ATI, and 'Deep color for 3D applications' for nVidia)
Enable OpenGL hardware support (under Preferences, Performance, 'Enable OpenGL Drawing' in PS CS5)
So will this be supported in Lightroom 3 before long? Or perhaps it is already??
Anyone know this?
Thanks, Paul
p.s. I realise the above chain of requirements sounds complex, but I got it working this week for a new PC build and it was actually quite straightforward.

What would be the advantage of this?
If you google around for how many colours the human eye is able to distinguish, you'll find scientific research quoting numbers around 10.000.000.
Horribly false.
The prevalent sRGB color space is covered fairly well by the 8 bits per pixel depth most commonly used ("32 bit" or "True Color" color in Windows), and that is about 16.7 million colors. While bit depth and color space are different things, once you go to the wider gamuts in other color spaces such as Adobe RGB without using more bits you will start to see banding in similarly colored (blue skies is a good example) areas because there are not enough digital steps to make smooth transitions as the color gradually changes. Take my word for it (I've seen it in many of my own pictures.) or do more reading for more details if it's not clear, but the key points follow.
First go to:
http://en.wikipedia.org/wiki/XvYCC
and read about the xvYCC color space. In their reference number 2 down toward the bottom of the web page you find a link to:
http://data.memberclicks.com/site/hopa/2007_xvYCC_forHPA_FINAL.pdf
which is a pdf of a presentation discussing extended gamut color spaces. Check out slide 3 which is at the bottom left of page 1 to see examples of many things in the real world that are quite visible to humans but outside of sRGB.
Next check out slide 19 at the bottom left of the 5th page to see just how pathetic sRGB is at covering human vision. The small pictures on the right in this slide show the coverage of the various color spaces of the "Munsell Color Cascade". The gray areas indicate colors that each space cannot cover, and you can see sRGB has huge blotches of gray.
Munsell did some of the very early definitive lab testing of human color perception. You can start reading about him and his color system here:
http://en.wikipedia.org/wiki/Munsell_color_system
and continue reading other links found on that page for more info about the extensive lab testing of human color perception.
Looking back at slide 4 on page 1 of the presentation linked above you will find an odd looking colored region that is curved around the top. It looks like this:
That colored region is the estimated range of standard human vision. There is a version of that which has the sRGB color space shown on it at:
http://en.wikipedia.org/wiki/File:Cie_Chart_with_sRGB_gamut_by_spigget.png
And that large view also gives you a much better idea of just how pathetically inadequate the sRGB color space is at covering human vision. Again, bit depth is not color space, but 8 bits per pixel is pretty much maxed out trying to represent the sRGB color space without having to fake colors within it's triangle.
There are probably cases where banding can be seen even in purely sRGB images with only 8 bits per pixel. And every color that you see in that large region with the curve at the top (in the picture shown in the last link above) that lies outside the sRGB triangle will have to be "clipped", which is converted into some color that does lie within the space. That means you never see any actual colors that fall outside the triangle even if 8 bits per pixel could have covered them somehow using some other color space. They're simply lost.
If you do try to use 8 bits for wider gamut color spaces you end up with the banding I mention above because there are too many shades of color to be represented by 256 steps for each of red, green, and blue. Thus the need for 10 bits or more per pixel.
I hope this helps to dispel any more myths about the limitations of human vision falling within what 8 bits per pixel or sRGB can provide.

Any hope of getting 64 bit twain plug in for Windows 64 bit Photoshop

Just what the title sez: any hope of getting 64 bit twain plug in for Windows 64 bit Photoshop? Frustrating to upgrade and have to do a work around to use your scanner. Will Adobe release this?

Chris,
I have a CanoScan 8800F plus CS5, both 32-bit and 64-bit versions installed. When I scan four slides in a holder, the 32-bit TWAIN driver/plugin gives me four images of one slide each. The 64-bit WIA driver/plugin gives me one image of the slide holder, with the four slides in it. Is this a limitation of the WIA technique in general or the particular WIA driver for my CanoScan?
Best regards,
Antero

16 bit printing in Lightroom for Windows

According to a Lightroom 2 video from NAPP about printing, Scott Kelby states that 16 bit output is only available if you have OSX Leopard because it is an operating system specific feature, and Windows does not support 16 bit printing. However, Canon supplies a Photoshop plugin with the iPF5100 printer that supports 16 bit output regardless of the operating system in use. So I'm just curious why Lightroom doesn't support 16 bit output for Windows, but Photoshop does? Or am I missing something?
I've also asked the question at answers.microsoft.com if Windows 7 is going to support 16 bit printing, and a Microsoft MVP said "If a 16-bit print driver is created for the printer, 7 will not stop it from doing that. How an image is converted to print is not an OS limitation. The print driver does that." So who am I to believe? I would imagine that if Windows was capable of 16 bit print output then Adobe would support it on the Windows platform right? So if anyone from Adobe can answer this question, I would greatly appreciate it.
Regards,
Dean

When it comes to printing, LR talks to the OS, and the OS talks to the printer driver. Therefore, if LR supports 16-bit printing, the driver supports 16-bit printing, but the OS only supports 8-bit printing, then there's no benefit. The Canon PS plug-in is different because the OS is not involved; the plug-in is effectively talking directly to the printer driver.
That said, I do not know for certain which versions of Windows support 16-bit print paths, not having investigated the matter myself.
(I also humbly suggest that it's not as big of a deal as you might think. One the list of technical matters that factor into print quality, I'd have to rank 8-bit vs 16-bit printing as being pretty far towards the bottom.)

64-bit version of Quicktime for Windows

I'm running 64-bit version of Windows 7 via bootcamp. I'm running 64-bit version of Microsoft Office 2010. I have the latest version of Quicktime installed 7.7.3 something. I can play the file on the desktop no problem, but when I try to insert the file into Powerpoint or play a file that I inserted previously into Powerpoint on a different system, it says either Quicktime unavailable or you need a 64-bit version of Quicktime in order to insert the file.
So, exactly where is a 64-bit version of Quicktime for Windows because apparently the one on the Apple website for Windows is not 64-bit. Everyone keeps saying download the 64-bit version of Quicktime. Great, tell me where it is. There is no option for 64-bit on the website. It doesn't even say it is 64-bit. It just says its compatible with Windows 7. Powerpoint 2010 64-bit MUST have a 64-bit version of Quicktime in order to insert or play any Quicktime file. The OS doesn't give a rats @ss one way or the other.
The file I previously inserted was playing on a system that apparently had a 32-bit version of Powerpoint installed. That machine defaults to VLC player on the desktop. It has no issues with the file. It's the Quicktime Player mismatch on my machine that is giving me grief. If I knew Office was going to be a PITA if I installed the 64-bit version I would have stuck with the 32-bit version.
Ideas? Where is the 64-bit version? How do you tell it is 64-bit? How do you force the installer to make sure it ONLY installs a 64-bit version of it?

If Microsoft merely off their own decided that only a 64-bit version of QuickTime was going to be supported by them and did not both checking such a beast existed then this is perfectly believable behavior on the part of Microsoft and they should roast in **** for it.
If Apple led Microsoft to believe that a 64-bit version of QuickTime was going to be released like a 64-bit version of iTunes for Windows has been released but then backed out then this is equally believeable behaviour on the part of Apple and then equally the guilty parties at Apple should roast in ****.
It should be noted that the 64-bit version of iTunes is able to play videos via the 32-bit version of QuickTime. This suggests Microsoft programmers are weak with the force. This would tend to support my theory that Microsoft despite being the biggest software company in the world are better at making hardware than software.
Moving on to trying to be more constructive…
Clearly as things stand using the existing and only official version of QuickTime for Windows which is 32-bit only is not going to work in 64-bit Office. It might therefore be worth looking at trying the following.
Uninstall completely Apple's 32-bit QuickTime for Windows (if installed currently)
Install QuickTime Alternative - see http://www.free-codecs.com/download/QuickTime_Alternative.htm
I have no idea if QuickTime Alternative is 64-bit, I have no idea if it will work in 64-bit Office even if it is 64-bit. However it does work in Internet Explorer for Windows, it is free and therefore will cost you nothing to try. If it does not work you can then always uninstall it.
As another even more abtruse solution, you could try loading your PowerPoint file in to the free iWorks i.e. KeyNote via a free iCloud account. It will allow importing PowerPoint files and will even work in Internet Explorer.
