synchroization and timing Analog in, digital in and CAN on Crio9045 using daqmx (9220, 9425, 9361 and 9862)

[foxer0101]

Hello 

I'm looking for the best way to synchronize Analog in, Digital in and CAN measurements on various C series modules in my Crio 9045. 
I have C series modues: 9220, 9425, 9361 and 9862 and I'm using daqmx.

I'm specifically looking for how to select and share a source signal for 'sample clock'. 

If I can avoid this, I don't want to create an external trigger signal or clock. 

Attached you can find a snippet of a part of my code, on which I gave up fixing this timing for a while. I tried several things in the past. 

I hope someone wants to point me in the right direction.

Hi Kristof, 

Since you are using a cRIO with DAQmx, and using the DAQmx API to read data,  I would recommend reading the DAQmx Sync info, like section 4 here http://www.ni.com/tutorial/5376/en/#toc4 and the Synchronization Beyond Analog section here
