"DDK with the NI 6602 and example programm gpct_ex8.cpp"

[M.Behn]

"Hello,

I got from NI the following the Measurement Hardware Driver Development Kit
for the NI 6602 Counter/Timer Card to work with Linux:


http://sine.ni.com/apps/we/nioc. vp?cid=11737〈=US


one is the common driver.


The other are the sample programms.


However, every programm except the one which uses the
interupt/dma works(gpct_ex8.cpp).


Here is the errormessages:

Does anyone know what is the problem with it?


I have Redhat-Linux 8.0 and kernel 2.4.18.


Thank you

Mario,

Unfortunately the TIO ChipObject included in the MH DDK for the 660x is missing a number of registers. I have attached the update TIO ChipObject to this note. In addition you should edit the call to the G0_DMA_Control_Register in the example. Instead of G0_DMA_Control_Register it should reference G0_DMA_Config_Register instead. Please make this change manually in your code.
