Hi,

I was trying to find a way to calibrate my flexi force using labview but the problem is my limited knowledge in Labview and Interpolation. The attached program takes values via Daq and displays them and also it calculates the rate using the fact that Values above zero are considered as no pressure applied. When I attached the flexi force I ran into problems with calibration. So if you guys could help me out that would be nice.

Thank you

Hey,

guys back with another question, I need a crash course in directx so what is a good site or book to like quickly become familiar with.

thank you

1) You should initialize your shift-register.

2) You should measure the time your DAQ Assistant takes to execute; your rate calculation will be incorrect if it takes more than 100mS.

3) Your DAQ Assistant is set to measure continuously; try setting it to Acquire N Samples.

4) You'll need to test the force to see if it's > 0 during each execution of the loop. If you have the force applied during multiple consecutive loops you'll have to assume that they're part of the same compression, so you need to find transitions from no force to force > 0. (Hint: I like the OpenG Boolean Trigger for this.)

5) This requires your loop to run fast enough to detect very short compression durations.

6) You should specify where you're stuck (so we don't have to guess).

Well Stated. And also true about the problem part. My problem is when I am attach the DAq to an function generator. The function generator is set to give out a square wave at a certain frequency which should be the rate in this or aleast inverse. this does not happen What i get is a very oscillatory rate almost like a sine wave with and exponential beginning.

so I wanted you guys to look at it and see what is going on.

hello All,

Novice back With Need help again. I am working on a project for school making a pad which will count how many times a person puts force on the person on whom the CPR is being performed. Basically Counting compressions per minute. So this is what I have so far, and I am sort of Stuck. If you guys could help me out.

Thank you

In OpenG lib, you can find the vi called 'String to 1D Array', you can then scan from each of these string for the number which you want to compare.

Maybe you understood me wrong. I wanted to change a string into an Integer Array.

Thank you

Hey all,

Back with a another noob question. I was trying to read from a .txt file when I finally achieved this i wanted to get the information in an array cause i was going to use each of these numbers for comparison. But I am having difficulty with this. So Can anyone help me.

Thank you

Hi,

It all depends on what you want to actually do with the split parts afterwards, there are several ways to skin this cat, typically you use the match pattern, match regular pattern , split string function in a while loop until you find no more matches. you can also do it all at once using the spreadsheet string to array.

That is a nice code. I really Like it.

what would be the difference between them in the sense that which will be faster.

The reason for comparing the password letter by letter is when someone is setting the password you confirm to make sure they didn't mistype the first time.

SO i thought i was done letter by letter.

Hi all

I understand this is sort of a silly to some even a stupid question I was wondering how would you do a letter by letter comparison. If you were making a

password program.

Thank you.

Definitely hang out on the forums and ask many many questions.

An interesting example is something as simple as a contact management program.

A more involved but useful program might be tracking expenses quicken like.

Or if you have a few dollars to spend, grab a USB Multi Function DAQ card along with a few relays, sensors and motors and automate something in your dorm room.

My personal favorite that never got implemented was just a basic door opener or re-inventing "The Clapper".

Actually I did do the code for the clapper to be honest, but never hooked up the relay to my parallel port.

Lol Yea I know about Clapper. Also if you could help me decide from where should buy if I can get i used one or a refurbished one.

But yea these seem like somethings I can do.

Thank you

Dear All

I recently took a class at school which taught me the basics of programing and programing in Labview.

I was wondering if there are other projects I can do which will help learn. Also are there any good books which are

a good read and also have like exercises at the end.

Thank you
