I've finished the programming of the process read and write for the PCI6025E, now I wanna synchronize both of the processes, writing the data into the card just after the reading from the card, and check the wave in the oscilloscope. when I use the SEC , it works, but when I changed to MSEC, the wave only come out for a few seconds, even if I bloc 60sec, and also the wave is not steady. why? how to figure it out?
thanks!!!!

Hi Jack,
Do you want to synchronize you analog input and analog output of your 6025E? If so, there are examples of this installed with DAQmx. You can find them at Start >> Programs >> National Instruments >> NI DAQ >> Text Base Code Support >> Visual C++ Examples. When you open the examples folder, double click Synchronization >> Multi Function >> SyncAIAO_DigStart. You can wire the output to both the analog input and the oscilloscope to monitor your signal.

hello :
I only can find Start >> Programs >> National Instruments >> NI DAQ, I didn't see " Text Base Code Support", I use the QNX Momentics IDE 6.3.0 Service Pack 3
thanks!!

Hello:
Thanks for your reply!
But I did programming in the QNX platform,It's QNX Momentics IDE 6.3.0 Service Pack 3.
How could I write the data immediately which just read and it's for a long time?
Thanks!

Hi Jack,
To use the QNX platform with National Instruments hardware, you will have to use the Driver Development Kit. Please take a look at the KnowledgeBase articles below.
Using Measurement Hardware DDK on QNX RTOS
What is the Measurement Hardware Driver Development Kit (DDK) and Who Supports It?
