-Driver: ni_pcidio
-Description: National Instruments PCI-DIO32HS, PCI-6533
-Author: ds
-Status: works
-Devices: [National Instruments] PCI-DIO-32HS (ni_pcidio)
-	 [National Instruments] PXI-6533, PCI-6533 (pxi-6533)
-	 [National Instruments] PCI-6534 (pci-6534)
-Updated: Mon, 09 Jan 2012 14:27:23 +0000
-
-The DIO32HS board appears as one subdevice, with 32 channels.
-Each channel is individually I/O configurable.  The channel order
-is 0=A0, 1=A1, 2=A2, ... 8=B0, 16=C0, 24=D0.  The driver only
-supports simple digital I/O; no handshaking is supported.
-
-DMA mostly works for the PCI-DIO32HS, but only in timed input mode.
-
-The PCI-DIO-32HS/PCI-6533 has a configurable external trigger. Setting
-scan_begin_arg to 0 or CR_EDGE triggers on the leading edge. Setting
-scan_begin_arg to CR_INVERT or (CR_EDGE | CR_INVERT) triggers on the
-trailing edge.
-
-This driver could be easily modified to support AT-MIO32HS and
-AT-MIO96.
-
-The PCI-6534 requires a firmware upload after power-up to work, the
-firmware data and instructions for loading it with comedi_config
-it are contained in the
-comedi_nonfree_firmware tarball available from http://www.comedi.org
