intermediate result display

[Boris_Epel]

Hi, I have an analog input task which slowly reads finite amount of data. I need to display intermediate results :

request N points

start

while all data not ready

    get what is ready (M pts)

    diplay what is ready (1st to M pts)

    wait a little

diplay all (1st to N pts)

clear

what is the best implementation of this protocol in ANSI C ? if i use DAQmxReadAnalogF64 do i need to append each ready chunk of data myself ?

Thanks!

Hi Boris,

It depends on how you configure the DAQmxReadAnalogF64. The numSampsPerChan determines the number of samples, per channel, to read.

If the task acquires samples continuously and you set this parameter to -1, this function reads all the samples currently available in the buffer.

Take a look at this page and see if that helps answer your question:
