- * 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)
