Problem in stopping task in continuous data acquisition using DAQMx C API

[Sameer78]

I'm trying to do the continuous data acquisition in PCIe-6536 using DAQMx C API. But whenever I try to clear the task and terminate my application, program halts and it is not terminated even by the task manager  and task killer applications. Can anybody help me in this regard?

Hi Sameer,

Are you running one of the shipping examples?  If so, which one?  If not, could you try running the following example:

Start >> All Programs >> National Instruments >>  NI DAQ >> Text-Based Code >> ANSI C Examples >>Digital >> Read Values >> Cont Read Dig Chan-Ext Clk

If using the on-board clock, you can change the clock source to the internal clock.

Also, which version of DAQmx do you have installed, and which development environment are you using?

Hi John,

          thanx for your concerns. the shipped example was also creating the same problem. Then I run the self test of device in MAX and it failed. Then I realized that there is something wrong with installation. I simply unistalled the card, and installed it on other PCI-e slot. This time self test was passed and so did my application.

Hence my problem was solved 🙂

Once again thanking you for your early response.
