-Driver: pcmmio
-Description: A driver for the PCM-MIO multifunction board
-Devices: [Winsystems] PCM-MIO (pcmmio)
-Author: Calin Culianu <calin@ajvar.org>
-Updated: Wed, May 16 2007 16:21:10 -0500
-Status: works
-
-A driver for the relatively new PCM-MIO multifunction board from
-Winsystems.  This board is a PC-104 based I/O board.  It contains
-four subdevices:
-  subdevice 0 - 16 channels of 16-bit AI
-  subdevice 1 - 8 channels of 16-bit AO
-  subdevice 2 - first 24 channels of the 48 channel of DIO
-	(with edge-triggered interrupt support)
-  subdevice 3 - last 24 channels of the 48 channel DIO
-	(no interrupt support for this bank of channels)
-
-  Some notes:
-
-  Synchronous reads and writes are the only things implemented for AI and AO,
-  even though the hardware itself can do streaming acquisition, etc.  Anyone
-  want to add asynchronous I/O for AI/AO as a feature?  Be my guest...
-
-  Asynchronous I/O for the DIO subdevices *is* implemented, however!  They are
-  basically edge-triggered interrupts for any configuration of the first
-  24 DIO-lines.
-
-  Also note that this interrupt support is untested.
-
-  A few words about edge-detection IRQ support (commands on DIO):

  * To use edge-detection IRQ support for the DIO subdevice, pass the IRQ

-    but rather configured through software, so any IRQ from 1-15 is OK.

  * Due to the genericity of the comedi API, you need to create a special
-    comedi_command in order to use edge-triggered interrupts for DIO.

+ * comedi_command in order to use edge-triggered interrupts for DIO.
+ *
  * Use comedi_commands with TRIG_NOW.  Your callback will be called each
-    time an edge is detected on the specified DIO line(s), and the data
-    values will be two sample_t's, which should be concatenated to form
-    one 32-bit unsigned int.  This value is the mask of channels that had
-    edges detected from your channel list.  Note that the bits positions
-    in the mask correspond to positions in your chanlist when you
-    specified the command and *not* channel id's!
