I would put 1/2meg of acquisition ram on the a2d board and then not worry about dma at all.

I'm using ADC0820 as A2D and also data transfer through ISA bus . My question is about PC part.Is it nessecary to use DMA transfer? Do you know a C library which ease the DMA programming? Can a nonreal time OS like windows do the job? What about the DOS?
