Max6675 for k-type thermocouple temperature reading using arduino and labview

Hi; I am trying to measure temperature using arduino mega +labview 2013 +k-type thermocouple+max6675.
I am using LIFA interface.
The circuit digram and labview file is attatched
I am stuck on spi read/write palet. How to read 12 bit max reading and convert it to temperature in degree celcious?
Max6675 produce output in 12 bit, and measure 0-1023 centegrade. According to this the
Temperature (C0)= max6675 output (12bit)* 0.25. how to set this formula in labview?
Pin connections are
Max6675 breakout board pins

Acquiring images from an Analog Camera using Arduino and LabVIEW

Hi All,
I posted this on the LabVIEW Arduino community but I am not sure it went through.
Check out this project I have been working on for the last two weeks.
It allows you to capture lowres/low bit depth images with arduino with LabVIEW (needs NI vision).
Here is the link
Feel free to use the code (it is all downloadable).

Hello cagell
I just wanted to exprees my thanks for sharing your awesome project with our community. I am a huge analog video enthusiast myself. All the best!
Sincerely,

Is there a DJ app for the Ipad that will read the "start" and "stop time" setting for each individual song, as they are set in the song Options screen in Itunes?

Is there a DJ app for the Ipad that will read the "start" and "stop time" setting for each individual song, as they are set in the song Options screen in Itunes? The Ipod Touch, by itself does not allow cross-fading, therefore when the stop time is edited short, the song jusst truncates then goes to the next song. I tried the DJay ap and while it would crossfade, it would NOT read the song settings for the stop marker. So now I want to try and Ipad and see if there is an app that will READ the Itune stop settings within the song. I do NOT want an app that will allow me to DO the stop marker. I want an app that will READ the stop marker from the song as it is set in Itunes.

Itunes provides the option for setting the Start and Stop times of each music track. However, the start and stop times do not synchronize to the iPhone. I don't understand why this option is even available as it doesn't work when listening to music on the phone. I have not found another application that will support the start and stop time markets. I have searched quite a bit for this but can't find anything. I hope we can find something.

No sound for incoming calls but it works using speaker and earpiece. I can't hear anything but the other party can hear me clearly. I was told it's hardware problem. Would anyone please help? Thanks

This is an annoying problem for many people. Most likely your dock connector (on the bottom where you plug in your phone) is dirty or screwed up and is probably just coincidence that it happened after you updated. Some people have had success cleaning the port with a dry clean tooth brush. There is a long discussion going on at the thread I linked below. Good luck...

I am having trouble using reverb of any kind; it does not sound natural, but rather "pixilated." Does anyone have any ideas for a solution? I have used Silververb and Space Designer and am having the same problem...

I am using Logic Pro 9 with two MXL 990 microphones in my piano and a Rode NT1A for vocals. I have tried recording with added reverb and keeping getting not a natural reverb sound, but a rather "pixilated" one that does not sound natural. Does anyone have any ideas on how to solve this issue? I have tried using Silververb and Space Designer, and both result in the same problems. Thank you!

This is asking for the impossible! It does not sound natural because maybe it isn't and in judging so whats your reference anyway. If you are in dire need of some natural sounding room you can go and record it yourself. But even then, the chances that it sounds like you imagined it, are very slim.
There are very decent sounding reverberation plugins, based on artificial reverb generators or convolution-style, the last one is said to sound more 'natural' then the first one. Be it as it maybe, it really is like cooking food. You got all the ingredients for this delicious taste at hand and believe it or not to reach a satisfying result this is not enough, because if you do not mix the ingredients in the right proportion you will end up with a different dish you thought you'll get. This is exactly the same when one would mix audio, I dare say.
So treat yourself to some good ingredients and the rest is up to you, namely: taste and experience!
And looking at some of my past music productions I always find the same plugins for the 'ambient' task:
Altiverb by Audio Ease when I have acoustic ensembles (classical music mostly), the Sony Oxford Reverb in studio productions, Bricasti when I have to deal with drums and MMultiBandReverb from MeldaProduction for all-round stuff. Thats the base I start from, after that I can end up with dozen Reverb plugins which basically all are doing the same thing but just in a tiny different way.

I am using fieldpoint and labview to log and monitor the temperatures of my system. but i am not using Labview 6i with DSC, how can i do it??

i am using fieldpoint 2.0 and labview 6i to monitor my system, but i think i don't have labview DSC.

I have written a relatively large Fieldpoint application "just" using LV5.1 FDS, so it can be done.
Fieldpoint can be seen as an external instrument, so you need to use the driver/vi's that comes with FP.
I believe using DSC would only make the job easier for you.

Servo motor control using MCB2300 and Labview

Hello Everyone,
I have to drive servo motor using MCB2300 board and labview. I am new to LabView as well as MCB2300 board. I understand that I have to generate Pulse to control the servo motor.
I have gone through some of the post but could not find something useful.
I need to do it asap, a fast and eloborating answer is much appreciated.
Thanks is advanced.

I don't know if this will help you, but think about this tip:
On the back of my (digital-) Servo package there was some data written (see attached image).
You've heard of PWM (Pulse Width Modulation)? If not look it up in
wikipedia / microcontroller.net / (if you speak german) http://www.rn-wissen.de/index.php/Servos or google
The description of the Servo says that I have to send every 200ms +/- 1ms a positive (+5V +/- 1V) signal with a length depending on the angle I want the Servo to be set. The Signal is coded in conjunction to time, which means, as longer the Signal as higher the angle is. The Signal range is in between 70 to 240 ms (with my servo and not exactly). The Signal must repeated every 200 ms like I said before. I don't know, if you understand C but here is a function I wrote, which works fine for me:
void set_Servo_0(uint8_t angle)
DDRA |= 2; // Specific Port declaration for my µC (Atmel)
uint8_t tick; // a var to count how often I send my Signal
for(tick = 0; tick < 2; tick++) // loop to count -> send Signal three times
if(getStopwatch1() > 200) // getStopwatch is a libary specific function to measure time in ms steps
PORTA |= 1; // port high
sleep(angle); // angle comes from outside the function, it is a parameter for this function. Sleep for this time with port high = pos Signal
PORTA &= ~1; // then pull down
setStopwatch1(0); // reset the timer
mSleep(250); // Finally I have to wait for this time (in ms) when I send different angle parameters one after another, to let the whole system
// (µC + Servo and rest of program) to settle down, else I will loose signal steps due to incorrect timing (not nice, but works).
This function gets the angle as Integer from 7 to 24 and puts the Servo in corresponding position one time.
Maybe You can adapt it, good luck.

I am looking for what type/setup of Read/Write command in RSLogix 5000 to be used with the NI Ethernet I/P Driver

I am working on trying to get LabView to communicate with an Allen-Bradley Compact Logix PLC using the NI Ethernet I/P driver. I am currently getting errors on both system of a CIP Message instruction error and cannot determine if the problem is in the PLC or the NI. At this time we are leaning toward the PLC, thus I was wondering if anyone new what type/setup of message read and write to utilize.

Hello jabcae,
Thank you very much for posting your questions.
I recommend posting to the PLC Manufacture’s forums. They will be able to provide more insight on the PLC code.
I also recommend posting this question to the Industrial Communications forum:
http://forums.ni.com/t5/Industrial-Communications/bd-p/260
That forum is monitored by the developer’s of the EtherNet I/P Toolkit. They will be able to assist with the LabVIEW programming.

Need to find a driver for cRIO-9211 thermocouple to be used with LabView

I am using the NI cRIO-9211 Thermocouple input and the NI USB-9162 Hi-Speed USB Carrier and need to find a driver to interface the thermocouple with LabView 8.5.1. Could you point me in the right direction as to where I can download a driver for this?

Hi Durnan,
You will require the DAQmx driver for the USB 9162. This can be found here: ni.com/downloads, see DAQmx 8.8 - would do.
You only require the DAQmx driver, as the C Series modules are supported - they can just be used in a cRIO as well.
Hope this helps,
Kind Regards,
James.

How do I create a new folder for saving a PDF in Reader using Windows 8.1?

I used to be able to create a folder in which to save a PDF. With the new Reader in Windows 8.1, I have not found that option.

Wow. The light bulb just went off! I have the Reader that was installed on my HP notebook and - you are right - it is the Microsoft Reader. I just assumed it was Adobe's product which I have used for years. No wonder I can't find the options I generally used.
I will download the Adobe Reader. Thank you for your feedback and help!!!

I signed up for 20 bucks a month and only got one day of use of Photoshop. Where does that get off?

What error are you receiving? Do you have a subscription to Photoshop CS6?

I am trying to figure out how I can have a "main" itunes account for all purchases, but have seperate accounts for my children so they can use iMessage and other features of iPod touch. Also, they would be able to download free items.

Can you have one install of iTunes on a PC or Mac, but have multiple Apple IDs tied to it?

You can't have multiple IDs associated with an itunes account, but you can have one ID one 1 device and another one, but currently its impossible to merge accounts.

I-movie. I made a movie for a party of my daughters using photos and music. The video looks great on my Mac but when I burned a dvd and watched it on several t.v.s it looked like crap. The pictures looked blurry because of the movement of transitions?

Does anyone have ideas to sharpen the video i made. Looks good on computer but not on tv. the transition between pictures blurs the images. Is it my tv that causes this?

Control CS-200 Konica Minolta chromameter using USB and labview

Hi,
Does any body have any ideas about controling a Konica Minolta CS-200 chromameter using Labview. The Chromameter has an USB interface to the computer that is controlled by its own software. I dont think there is a command language available for this or any such thing. But is there a brute force way of reading measurements from CS-200.
Thank you, Jignesh

I developed a LabVIEW application a few years ago that use the Minolta
CA210 color analyzers. I used the ActiveX controls in LabVIEW to
interface to the unit via USB (RS232 as well). The unit came with
software that you had to install on the target computer (it put the
DLLs used to control the unit in the windows system folder and added
registry entries). There was a SDK manual that showed all of the
methods and properties in the DLLs; once I figured out how to make
calls via ActiveX, I was able to control the unit.
Hopefully the CS-200 can be controlled similarly. I've attached a subVI used to initialize a CA210; hope this helps!

Using FPGA and Labview without RIO board.

Dear Sir
I am a student. I want to connect my own FPGA and make a program on labview and then transfer to FPGA.I do not want to buy RIO.Is it possible to work
like that without purchasing RIO.
Thanks a Regards

The PCIe and PXI cards you mentioned are specifically RIO.
But you managed to program a USB-6225 with LV FPGA? I'm not even sure there is an FPGA on there to program. It is an M series DAQ board.
