Data Acquisition With 6533

[nicogt]

I had to acquier data from 3 DIO-32HS in synchronising the acquisition with "change detection". Next i had to write these data in a file.

It is for this second step, i have some difficulties (for the first, i took one of the example, an i adapted it). For example, I don't exactly know, if i had to work with a circular buffer, or with a normal, or if i must change my parameters of synchronisation(to increase frequency, ....)

Oups, i forget saying that i must work in continue at a 2 kHz frequency.

So, if you have an idea to begin or more, thanks to answer.

Finally, I have programmmed all the step and i can do data acquisition. But there is a problem, i have a limit of 200 Hz. In fact, if frequency is more important than this limit, the file (where there is data) is more important and have some false value.

If someone have an explain to this phenomen , i accept it with pleasure.
