  14 * Driver: ni_labpc_cs
  15 * Description: National Instruments Lab-PC (& compatibles)
  16 * Author: Frank Mori Hess <fmhess@users.sourceforge.net>
  17 * Devices: [National Instruments] DAQCard-1200 (daqcard-1200)
  18 * Status: works
  19 *
  20 * Thanks go to Fredrik Lingvall for much testing and perseverance in
  21 * helping to debug daqcard-1200 support.
  22 *
  23 * The 1200 series boards have onboard calibration dacs for correcting
  24 * analog input/output offsets and gains. The proper settings for these
  25 * caldacs are stored on the board's eeprom. To read the caldac values
  26 * from the eeprom and store them into a file that can be then be used by
  27 * comedilib, use the comedi_calibrate program.
  28 *
  29 * Configuration options: none
  30 *
  31 * The daqcard-1200 has quirky chanlist requirements when scanning multiple
  32 * channels. Multiple channel scan sequence must start at highest channel,
  33 * then decrement down to channel 0.  Chanlists consisting of all one channel
  34 * are also legal, and allow you to pace conversions in bursts.
