Driver: das16m1
Description: CIO-DAS16/M1
Author: Frank Mori Hess <fmhess@users.sourceforge.net>
Devices: [Measurement Computing] CIO-DAS16/M1 (das16m1)
Status: works
This driver supports a single board - the CIO-DAS16/M1.
As far as I know, there are no other boards that have
the same register layout. Even the CIO-DAS16/M1/16 is
significantly different.
I was _barely_ able to reach the full 1 MHz capability
of this board, using a hard real-time interrupt
(set the TRIG_RT flag in your struct comedi_cmd and use
rtlinux or RTAI). The board can't do dma, so the bottleneck is
pulling the data across the ISA bus. I timed the interrupt
handler, and it took my computer ~470 microseconds to pull 512
samples from the board. So at 1 Mhz sampling rate,
expect your CPU to be spending almost all of its
time in the interrupt handler.
This board has some unusual restrictions for its channel/gain list. If the
list has 2 or more channels in it, then two conditions must be satisfied:
(1) - even/odd channels must appear at even/odd indices in the list
(2) - the list must have an even number of entries.
Options:
[0] - base io address
[1] - irq (optional, but you probably want it)
irq can be omitted, although the cmd interface will not work without it.
