See attached vi. It contains code on how to write your data to a file. I put comments in a red text block. Had to change some things like making loops stop after one iteration because I don't have anything on my serial port. You can change them back or just copy the added code for file writing into your existing vi. Basically what I did was to open a file, convert the retrieved data from a number into a string, concatenated the data into a single string with commas separating the data and an end of line constant to terminate the string, then write the line to a file. I did the same for the next case which collected wind data. When the stop button is pushed, the file is closed. If you look at the file that is generated, you will see something like:
12.4, 45, 56.23 (this is pressure, temperature, humidity)
34, 45 (this is wind speed and direction)
The last line may be repeated 5 times with different data because your code does 5 loops. Anyway, I hope you get the idea on how to write sequential data to a file. You can add labels and headers by concatenating labels before the data, and writing a header to the file before the loop begins.
