How to develope some softwares to control 2 DAQ cards(5102)

[alex.]

We are trying to develope some softwares to control 2 DAQ cards(5102) to collect view and analyse the data. And set for sampling rate, time interval etc.
And we need to trigger the total 4 channels at the same time.
May you give any hints where should we start, any driver toolkit.
 
Best Regards,

Depends on what you want to do, but this is one way to do it.

Configure task 1, configure task 2 (task 1 and 2 have the same hardware triggrer and both tasks are triggered to start on same signal either through RTSI or physically wiring).  Inside of a loop, read task 1 read task 2 (depends on the relative rates of the tasks you might need 2 parallel loops) when daq is cone, exit the read loop and close the tasks.

Is there any driver software for samples I can look into? Or any other tools I can look into and start with it. Thanks.

The 5102 is a special daq board and you won't use the NI-DAQ functions. It comes with a special driver called NI-Scope and the driver includes some examples. You can check https://www.ni.com/en/support/downloads/drivers/download.ni-scope.html for links to the driver and manuals.
