synchronizing serial and daq data

[ritaraujo]

Hi,

I'm attempting to acquire simultaneous data from a serial port and a NI USB-6211 board.

I wish to write the data simultaneously and at every second.

At first the I couldn´t acquire the data as i wanted because there were delays in the acquisition, but then I separeted both serial and daq in two loops and it was solved. However now I can´t manage to write the data simultaneously into the file.

Any Ideas?

Thank you.

Would it be possible to post your code?

You could sync your loops with a "wait until next ms tick with a value of 1000.  This would cause both loops to execute once ever second at at the same time.

It sounds like you now have a problem of writing the data to a file at the same time.  You could put for file write in a third loop and transfer your data from the other two via queues or functional globals and then write to the file when both peices of data are ready.

I used the global variables and it worked!

Thanks!:)
