However, if you wish to use the \fIAIO8-P\fP standalone, -insert the following into your kernel -.Xr config 8 -file: -.Bd -literal -offset indent -options ALOG_CHANNELS=8 -.Ed -.Pp -Selection of the input port is through the minor number: -.Pp -.Bd -literal -offset indent -The 8 bit minor number format is UCCCCMMM, where - U: board unit (0-1) -CCCC: external multiplexer channel (0-15) (on AT-16P units) - MMM: internal multiplexer channel (0-7) (on AIO8-P card) -.Ed -.Pp -.Xr devfs 5 -device node names are of the form: alog[0-1][a-p][0-7] -.Pp -.Sh IOCTL -The following -.Xr ioctl 2 -calls apply to -.Nm -devices. Their declaration can be found in the header files -.Pa <sys/alogio.h> -and -.Pa <sys/dataacq.h> -.Bl -tag -width AD_MICRO_PERIOD_SET -.It Dv AD_MICRO_PERIOD_SET -Takes a pointer to a long argument specifying the number of microseconds -between samples. Half of this is used as the external multiplexer -settling time and the other half as conversion time. -.It Dv AD_MICRO_PERIOD_GET -Takes a pointer to a long argument and returns the current number of -microseconds between samples. -.It Dv AD_NCHANS_GET -Takes a pointer to an integer and returns the number of channels the board -supports. This should be 8 for a standalone \fIAIO8-P\fP or 128 for any -other setup. -.It Dv AD_FIFOSIZE_GET -Takes a pointer to an integer and returns the size of the fifo in -entries. The compile time option ALOG_FIFOSIZE is by default set to 64. -.It Dv AD_FIFO_TRIGGER_GET -Takes a pointer to an integer and returns the minimum number of entries a -fifo must contain to cause -.Xr poll 2 -to return. This by default is set to 1. -.It Dv AD_FIFO_TRIGGER_SET -Takes a pointer to an integer specifying the minimum number of entries a -fifo must contain to cause -.Xr poll 2 -to return. -.It Dv AD_START -Starts the clocked accumulation of sample values into a channel's driver fifo. -When a channel is first opened its software fifo is initialized in the -stopped state. This is to prevent high sample clocks from overrunning the -fifos before the user is ready to read from the channel. The driver -automatically performs an AD_START when the user issues the first read, -except for channels opened with the O_NONBLOCK flag which must explicitly -have an AD_START issued. -.It Dv AD_STOP -Stops the clocked accumulation of sample values into a channel's driver fifo. -.Sh BUGS -On the \fIAIO8-P\fP, interrupt driven conversion (the only type -supported by the -.Nm -driver) is facilitated through 8253 timer #2. In order for interrupts to -be generated you must connect line 6 to line 24 (counter 2 output to -interrupt input) and line 23 to line 29 (counter 2 gate to +5VDC). -The design of the \fIAIO8-P\fP precludes the use of programmable -gain control. -.Pp -Use the combination of non-blocking i/o, -.Xr poll 2 -and a custom fifo trigger -wherever possible, especially with large numbers of open channels. -Using this method, multichannel sample rates as high as 16,000 samples/sec -have been observed. -.Pp -Sample rates lower than 32 Hz are not supported. -.Sh SEE ALSO -.Bd -literal -http://www.scottibox.com -http://www.indcompsrc.com/products/data/html/aio8g-p.html -http://www.indcompsrc.com/products/data/html/at16-p.html -.Ed -.Sh AUTHORS -.An Jamil J.
