Hi all, We have in our system REDHAT 9, kernel 2.4.22 vanila, patch adeos, RTAI 24.1.12, and the latest CVS comedi version. We are testing comedi adquiring at 1.25Ms/s. If we use only one PXI 6070E card we have not any problem to adquire at that speed, but when we use two cards (PXI 6070E) the adquisition of one of the cards is stopped (both cards at 1.25Ms/s). The other card continues working perfectly. We think that comedi moves data to their buffer when one card has a number of samples greater than PAGE_SIZE (4096) ¿is it right? If that is true, we think too, that increasing the number of samples to read at a time (for example 16K instead of 4K) we will improve the system, and adquiring from two cards at 1.25Ms/s each, will work. ¿what do you think about that idea? Thanks again Best regards -- Daniel Machón [damachon_at_eresmas.net] --
