Gaussian curve

[w1]

Hi,

I want to simulate a Gaussian curve in LV like there is option to simulate sine wave. Similarly, I want to generate a shape of Gaussian curve. I have tried with different techniques but still struggling.

Please help

Thanks in advance

Would this help?

Thanks for your reply, but how can I have only one curve since they appear to be many ?

[altenbach]

Well, remove all the code for the other curves. How hard could it be? 😄

(If you have problems with this, you should do a few LabVIEW tutorials first.)

Hi, 

I was able to implement the attached program and it does outputs a gaussian curve on the graph but i am trying to get something when I press run in LV so I could actually see the gaussian curve developing on the graph. Like there is option to genertae sine/cosine and you can see the output generation of the waveform. please help if possible.

thanks a lot

Place a FOR loop around the chart terminal (autoindexing on the array) and also place a small wait (e.g. 100ms) inside the for loop.

Thanks a lot. That works perfectly fine but I have one more question. Now I want the output of gaussian to be connected to Arduino's PWM pin so I can light up the lights and their intensity will increase with the waveform of the gaussian curve. when I made the connection they happen to be two different types. If you could have a look at the attached updated version of the same VI and suggest what can be done?

Thanks once again

If you want to send it point-by-point to the arduino, that also belongs inside (not after) the second FOR loop. Sorry, I don't have your toolkit, so I don't know what datatype it expects. can you tell us?

that arduino pin expects 8bit unsigned integer data. I have attached a screenshot for you.thanks

Two mistakes. You are feeding ot DBL data instead of U8 and you are feeding it an array instead of a scalar.

You simply need to scale the gaussian to the range 0..255, convert it to U8, and place the arduino tool inside the FOR loop.
