How to read Serial Data from Arduino using labview VISA?

[KnissM]

hey, I DID IT 

I can read the informations inside labview.

I'm having just one problem with my 'gas gauge' because Its no showing the right information. Do you know what is the problem? maybe some kind of convertion.

PS: I changed the whole code (i know i was told about the bytes at port... but it did work this way)

Why do you have the control marked PPM wired into the VISA Read number of bytes to read.  That doesn't make any sense!  You need to have a constant wired in there.  Pick 100.  As long as you don't have a message that will be longer than 100 bytes, it would work.

Also, you aren't doing anything with the output of the VISA read.

I would recommend looking at the online LabVIEW tutorials
LabVIEW Introduction Course - Three Hours
LabVIEW Introduction Course - Six Hours

here is the problem i told you before

[RavensFan]

If you follow the instructions given in previous messages, your VI will be a whole lot simpler, work, and look like this.

thanks a lot for the instructions.

i will see those videos.

last question, about the gas gauge...

It continuos to showing me the maximum number (it looks like it is at 100%)

Do you know why?

Really, THANKS A LOT!

[RavensFan]

Because that is what you have set for the limits of the gauge. 

Right click >> Properties >> Scale

Thank you so much!
