Continuous buffer with interrupts doesn't refill the buffer

[grivlis]

That is very curious. I cannot see how you will have a problem just including a source file in your own project. (you shouldn't use any of the previous files I sent, just that single new .cpp file).

Maybe your vs is misconfigured? Try to create a NON empty console win32 app and see if you can compile it. (I mean without any of my code).

Gil,

I can build a simple win32 console app, but if I add your code and link the nidaq32.lib I get the error.  It has something to do wtih spaces being some of the paths.  Can you send me the exe itself.  My device number is 1.  I can run it and verify what you are seeing.

Regards,

Kenn,

I use two cards, a 6602 and a 6533. Do you have access to both? If you send me the dev nums I'll compile one for you.

Also, try to copy the cpp file I sent into the directory in which you created your empty win32 app, and then add the file. Maybe it will work. I still cannot see where the path name is in my code...

Gil,

I will make the 6533 be Device 2.  How do you want me to add the file?

Regards,

(1) In visual studio create an empty win32 console application. Call it any name you want. For example we will choose 'ctrtest'.
(2) Copy the single file I send (which I attach to this message again) into the source code directory of the application you've just created.
(3) In VS, right-click the project name in the solution explorer and choose 'add->Existing Item...' and add the file you've just copied into that folder (ctrex.cpp).
(4) Try to compile.

I'll make a an executable as well

Hi Kenn,

Here is an executable. 6602 is device 1, 6533 is device 2
I packed it in a zip file because the forum's interface doesn't allow .exe files.

Gil,

Did that, and if I go to the project properties to link the nidaq32.lib I get the same error.  Is there another way to link that file?

Regards,

[grivlis]

Try to copy the nidaq32.lib to your project directory and link against that instead. You probably have a problem with your path.

(Did you tell VS2005 to look at certain directories for you library files? In the link properties in the project properties you should only put nidaq32.lib, and not the whole path. If you use the whole path, try to put quote marks (or maybe double quote marks) around it)

Is this what was expected.

hmm. not really. Is this from the executable I sent, or did you manage to compile to code?

Here is the result that I get (i've modified the code a bit to have a better printout). In this output there are two counters, counter 0 is DMA and counter 1 is interrupts.
The program prints out the conents of the beginning and end of each counter's buffer for the first 10 ticks of the DIO callback (to see that the buffer fills up) and then
also at the ticks around the time the buffer is supposed to get filled up (from tick 252). You can see how the DMA buffer refills and the interrupts one doesn't. You can also see that the counters are working properly, since they count the internal 100kHz source at 100Hz, so each tick we expect the counts to increment by 100 exactly (there is a small drift, becuase the clocks are not synchronized). I attach a new executable with two counters.
