serial scan until \r\n

[tayexdrums]

I have made the changes you suggested but I still don't think I am using the case structure correctly...

[Eric1977]

Make the 0 case display 0... --> that means that there was a EOL found anywhere within the string. A -1 will mean that no EOL was found.

Edit: Sorry, I told you wrong before. I don't think I've had enough coffee in me yet.

[Eric1977]

One more thing, make the 0... case default.

[tayexdrums]

Okay, I made the 0 case the default. Could you specifiy what you mean by "display?" I don't want to write a 0 to the text file.

[Eric1977]

No problem.

On the zero case, place your cursor next to the 0 and add two peroids, not three, so it displays like the image below.

Finally someone on here who is blatently clear! lol

I made the change but unfortunately no data is written to the text file. 

I clicked on the wire coming from the offset past match while the VI was running and it displayed a probe dialog window. The window displayed the values of going through the offset past match wire and I never saw a 0 or -1. It jumped around from 81 to 24 to a few other numbers.

These forumns have been giving my browser fits. Plus it would help if I could a) type correctly, and b) get the syntax right.

Post your vi, not the images.

Using google chrome?

This VI is meant to get serial data from a GPS module and print the NMEA strings to a text file for post-processing. I don't think you would be able to get anything useful out of running the VI. I won't deny you it though.

I like to use the Greater Or Equal 0 function to make things a little more clear.  It also helps that I use the structure label to say what question is driving the case structure.

[tayexdrums]

Tried that too. I think a better way to approach this would be this. Read the data in one byte at a time. Don't start to read until a $ is encountered. After a $ has been seen, start to print to the text file. Contine printing until a \r\n is seen. Go to a newline and repeat the process. Attached is the output from the last attempt using the greater than or equal function.
