Hi
1) First The documentation states that the ni_pcidio driver doesn't support
any handshaking uppon ni pci dio 32hs
does this mean that the driver sets the card to
- level-acknowledge
- ack signals are detected uppon leading edge \ as described by nidaq
- the req and ack signals are sensitive active high / manual for
DIG_GRP_CONFIG
Or could at least somebody send me the DIO 32HS register programming manual
(341329 and 341330a pdfs as ni has removed them from their ftp server, so
that I'm able to figure out that myselve ??
2) when doing async acquisiton like the mmap example uppon pci dio 32hs how
is the data placed inside the comedibuffer?
The aquisition should be simultanously don uppon 16 digital lines.
So how are the data comming allong these 16 lines placed inside the comedi
buffer?
a) bit by bit: means each 16 bit word contains a single bit from all of the
16 channels (bitmaplike)
b) byte by byte (word by word) from each line at least 8/16/32 bits are
read before the next line is read?

Christoph
