Driver: pcmda12

Description: A driver for the Winsystems PCM-D/A-12

Devices: [Winsystems] PCM-D/A-12 (pcmda12)

Author: Calin Culianu <calin@ajvar.org>

Updated: Fri, 13 Jan 2006 12:01:01 -0500

Status: works



A driver for the relatively straightforward-to-program PCM-D/A-12.

This board doesn't support commands, and the only way to set its

analog output range is to jumper the board.  As such,

comedi_data_write() ignores the range value specified.



The board uses 16 consecutive I/O addresses starting at the I/O port

base address.  Each address corresponds to the LSB then MSB of a

particular channel from 0-7.



Note that the board is not ISA-PNP capable and thus

needs the I/O port comedi_config parameter.



Note that passing a nonzero value as the second config option will

enable "simultaneous xfer" mode for this board, in which AO writes

will not take effect until a subsequent read of any AO channel.  This

is so that one can speed up programming by preloading all AO registers

with values before simultaneously setting them to take effect with one

read command.



Configuration Options:

  [0] - I/O port base address

  [1] - Do Simultaneous Xfer (see description)
