Data Streaming to HDD and Reading

[Biomedical Signal Processing]

Hi,

I have three channels at 1 KHz to 5 KHz selectable sampling rate. I would like to stream all three channels to disk in binary format with user supplied header / file name. I would like to watch data graph while continuously saving to disk and also need controls to select time duration to save data. I want to use same VI panel to read data with slider bar control. All three channels must show separate graph charts.

This is like simple data recording and reading application in same window with three channels and binary format.
Any help is highly appreciated,

I would be glad to help, but your posting sounds like you would like us to write the code for you. Have you started the project and have a specific question? You may want to look at the LabVIEW shipping examples. (open labVIEW 6.1 >> help >> find examples >> fundamentals >> file input and output. There are several examples for reading and writting to file. You may also be interested in the DAQ examples to see how to aquire the signal. Your outline for the slider suggests that you also need to know how to make a control work like an indicator and vise versa. This would be done with property nodes or local variables. Look for property examples at find examples >> programatically controlling VIs >> controlling front panel objects.
