   6    PCMCIA crap is adapted from dummy_cs.c 1.31 2001/08/24 12:13:13
   7    from the pcmcia package.

  23Driver: ni_labpc_cs
  24Description: National Instruments Lab-PC (& compatibles)
  25Author: Frank Mori Hess <fmhess@users.sourceforge.net>
  26Devices: [National Instruments] DAQCard-1200 (daqcard-1200)
  27Status: works
  28
  29Thanks go to Fredrik Lingvall for much testing and perseverance in
  30helping to debug daqcard-1200 support.
  31
  32The 1200 series boards have onboard calibration dacs for correcting
  33analog input/output offsets and gains.  The proper settings for these
  34caldacs are stored on the board's eeprom.  To read the caldac values
  35from the eeprom and store them into a file that can be then be used by
  36comedilib, use the comedi_calibrate program.
  37
  38Configuration options:
  39  none
  40
  41The daqcard-1200 has quirky chanlist requirements
  42when scanning multiple channels.  Multiple channel scan
  43sequence must start at highest channel, then decrement down to
  44channel 0.  Chanlists consisting of all one channel
  45are also legal, and allow you to pace conversions in bursts.
