DAQ voltage input and output tutorial CVI?

[aetherguy881]

I'm using a 6008 DAQ.

I've gotten the device to work when in the task editors, however I have been unable to get the code to work.

The error message I keep getting is:

NON-FATAL RUN-TIME ERROR:   "tmp.c", line 48, col 5, thread id 0x00001130:   Function DAQmxLoadTask: (return value == -200088 [0xfffcf268]). Task specified is invalid or does not exist. Task Name:   Status Code: -200088

Simply put, I want to read a voltage and output a resonse to it, on two seperate channels. I haven't worked with DAQ's before and I'm still relatively new to CVI.

Cvi and DAQmx come with a wide set of documentation material and examples that can help you in developing your applications.

The base help source is the DAQmx help, located in Start»All Programs»National Instruments»NI-DAQ»NI-DAQmx Help.

Additional sources are installed inside CVI online help: see the chapters

 Library Reference»NI-DAQmx Library 

 Using LabWindows/CVI»NI-DAQmx Concepts

Finally, the error you are reporting indicates that the task you are trying to load does not exists: this page from the online help can give you some useful informations on how to coordinate activities between MAX and CVI: Tools >> Create / Edit DAQmx tasks

The last source of informations is the Help >> Find examples... function, which helps you to locate the examples shipped with CVI; this function can also be used to search NI site for examples and can be tailored to match your actual hardware so that you are prompted only with relevant examples.
