请问在模拟输入任务中连续采集模式下,如果调用了DAQmxConfigureLogging()函数用TDMS文件保存数据的情况时,数据是如何写入TDMS文件中的,是否时在模拟任务开始后,系统会自动开辟一个专门的线程,将数据会自动的保存至TDMS文件中?
如果出现调用了DAQmxConfigureLogging(gTaskHandle,TDMSfilePath,DAQmx_Val_LogAndRead,"GroupName",DAQmx_Val_OpenOrCreate)函数,但是在模拟任务开始后,TDMS文件中有写入关于任务的组、通道等信息,但是却没有数据,可能的原因是什么呢?
我在一个程序中出现了上述问题,因为设置为了 LogAndRead模式,我用DAQmxReadAnalogF64()函数也能够读取到有效的数据,唯独在TDMS文件中没有数据。。。。Help,Help, Help
