store data crio

[antoniolc]

Goodmorning to everyone,

I am a university student and I have to do a project for my thesis with the COMPACT RIO, 

I have to store data by NI 9214 but I don't know how, I have already used the format TDMS, but after 15 minutes it become to much big, I tried with txt,  but CRIO doesn't recognize the character "return" or EOL, so if you have some advice to give me i thank you.

best regards, antonio

Hi Antonio to store channel measurments the TDMS file shoudl be a better fit than just a text file. TDMs are binary files so they will use less space than a txt file. The problem coudl be in that you are storing more datapoints than you need. You dont have to save files every time your code execute. So you can probably solve your problem just logging the information at a lower rate.

 How many channles are you logging? What is the size your expecting of the file? How often do you need to log your data?

You can find more information on the tdms in this page:
