If programed transfers are used instead of DMA there are two big advantages.
1) A24 DMA is no longer required. Thus it will no longer be necessary to modify the board support packages in order to support the NI1014.
I'm not quite sure I understand what you mean by this. Are you suggesting eliminating support for A24 DMA entirely in the BSP, or just for some quirk of the NI1014? We use the Kinetic Systems 2917 VME/CAMAC adapter, which uses A24 DMA. We definitely need to be able to continue to use these, there are a dozen or more in use on beamlines where they control a critical CAMAC device for multi-element fluorescence detectors. Mark Rivers
Thanks for the info. My interest is the NI1014. I don't see much reason for it to use DMA.
