Does someone have experience with programming analog-to-digital
and digital-to-analog converters with DJGPP ?
For high conversion rates (typ. 10 kHz), a simple polling procedure will
probably loose samples while the memory buffer is being copied to virtual
memory (expanded memory or disk memory) by go32.
I don't know whether DMA can access expanded memory directly, but even if
this is the case, there must be a way to "wire" those memory blocks
(to avoid them from being swapped out by go32), as is done on certain Unix
systems.
Will go32 2.0 have a provision for "wiring" memory blocks ?
A pointer to available source code would be mostly appreciated.
Please respond to pmertens AT cc3 DOT kuleuven DOT ac DOT be .
Thanks!
