Streaming I/O using DMA on a NI-PCI6111.

Hi,

we are trying to use the comedi libraries on a NI-PCI6111 and we have some problems.
What we want to do is to acquire continuously and to output the data (with some 
processing) at the same speed as fast as possible, all using analog channels.
We think that the best way to accomplish this is to use DMA but we have some 
problems. We started with the examples in the CVS sources and we were able to do 
simple input/output but we get an error (command_test failed) trying to run 
mmap.c.
Any hint on what is the best way to do what we need?

Thanks,
GianPiero
