National Instruments LABPC and LABPC+ driver
|
||||
.Sh SYNOPSIS
|
||||
.Cd "device labpc0 at isa? port 260 tty irq 5 vector labpcintr
|
||||
.Sh DESCRIPTION
|
||||
This supports the National Instruments LABPC and LABPC+ \fILow-Cost
|
||||
Multifunction I/O Board\fP.
|
||||
.sp
|
||||
This board provides 8 12 bit A-D input channels, 2 12 bit D-A output
|
||||
channels, and 3 8 bit digital I/O ports. It also supports setting
|
||||
up the National Instruments SCXI bus off the digital I/O ports,
|
||||
although that software is currently present in an external program
|
||||
and not as part of the driver.
|
||||
.Pp
|
||||
The selection of the input or output device, mode, and channel is
|
||||
through the minor number:
|
||||
.ES
|
||||
The 8 bit minor number format is UUSIDCCC, with
|
||||
UU: Board unit.
|
||||
S: SCAN bit for scan enable.
|
||||
I: INTERVAL for interval support
|
||||
D: 1: Digital I/O, 0: Analog I/O
|
||||
CCC: The channel selector:
|
||||
ANALOG:
|
||||
input: channel must be 0 to 7 for AD0 ... AD7
|
||||
output: channel must be 0 to 2
|
||||
0: D-A 0
|
||||
1: D-A 1
|
||||
2: Alternate channel 0 then 1
|
||||
|
||||
DIGITAL:
|
||||
input: Channel must be 0 to 2.
|
||||
output: Channel must be 0 to 2.
|
||||
.EE
|
||||
.Pp
|
||||
The /dev/MAKEDEV script will make the basic analog and digital
|
||||
devices if you do "sh MAKEDEV labpcaio" and "sh MAKEDEV labpcdio",
|
||||
however, it won't make device entries for INTERVAL and SCAN devices.
|
||||
SCAN devices automatically scan over all channels from the channel
|
||||
number down to 0 (for example, a SCAN for /dev/ad7 will read channels
|
||||
AD7 ... AD0) while the INTERVAL device will wait for an external
|
||||
signal and then read all the channels from the selected channel
|
||||
number down to 0 as fast as it can. This is done by the hardware
|
||||
and not the driver (other than turning it on); See the \fILabPC+
|
||||
User's Manual\fP and the source code if this doesn't make sense to
|
||||
you.
|
||||
.Pp
|
||||
The driver supports several Analog I/O ioctl calls. These are defined
|
||||
in sys/aio.h and are intended to be compatable with other AIO board
|
||||
device drivers.
|
||||
.Pp
|
||||
AD_MICRO_PERIOD_SET takes a pointer to a long argument specifying
|
||||
the number of microseconds between samples.
|
||||
.Pp
|
||||
AD_MICRO_PERIOD_GET takes a pointer to a long argument and returns
|
||||
the current number of microseconds between samples.
|
||||
.Pp
|
||||
AD_NGAINS_GET takes a pointer to an integer and returns the number
|
||||
of different gain settings the board supports. This is 8 for the
|
||||
LabPC board.
|
||||
.Pp
|
||||
AD_NCHANS_GET takes a pointer to an integer and returns the number
|
||||
of channels the board supports. This is 8 for the LabPC board.
|
||||
.Pp
|
||||
AD_SUPPORTED_GAINS returns an array of NGAINS (the number obtained
|
||||
by AD_NGAINS_GET) doubles. These are the gains the board supports.
|
||||
.Pp
|
||||
AD_GAINS_SET takes an array of NCHANS (the number obtained by
|
||||
AD_NCHANS_GET) integers and sets the board gains. These are indices
|
||||
into the supported gain array, with one gain for each channel.
|
||||
.Pp
|
||||
AD_GAINS_GET takes an array of NCHANS (returned by AD_NCHANS_GET)
|
||||
integers and returns the cuurrent board gains.
|
||||
.Sh SEE ALSO
|
||||
.Xr aio 1
|
||||
.Sh BUGS
|
||||
In general, only those capabilities that I needed are present. In
|
||||
particular the following notable restrictions are present.
|
||||
.sp
|
||||
The analog input is only supported in a clocked conversion mode.
|
||||
.Pp
|
||||
You can only set the sample clock down to 15 Hz. Anything slower
|
||||
needs a modification to the driver to support TCINTEN in order to
|
||||
chain together the counters to get a lower clock rate.
|
||||
.Pp
|
||||
There is no support for clocked D-A output.
|
||||
.Pp
|
||||
The 8255 providing the digital I/O ports is supported only in mode
|
||||
0 (three 8 bit ports).
|
||||
.Pp
|
||||
There is support for the SCXI bus off the LABPC board. It is not
|
||||
in the driver but is a separate user process that accesses the
|
||||
digital I/O devices. Ask dufault@hda.com for it.
|
||||
.Pp
|
||||
MAKEDEV only makes the "basic" devices. You must make the INTERVAL
|
||||
or SCAN devices by hand.
|
||||
.Pp
|
||||
The INTERVAL device sets the clock rate as high as possible so that
|
||||
it samples all the channels as quickly as it can after the external
|
||||
signal. This is a silly restriction; it should simply use the
|
||||
clock setting.
|
||||
.Sh CAVEATS
|
||||
National Instrument's (like most other laboratory grade board
|
||||
vendors) definition of Low-Cost differs dramatically from many on
|
||||
the net.
