Driver: ni_labpc_cs
Description: National Instruments Lab-PC (& compatibles)
Author: Frank Mori Hess <fmhess@users.sourceforge.net>
Devices: [National Instruments] DAQCard-1200 (daqcard-1200)
Status: works

Thanks go to Fredrik Lingvall for much testing and perseverance in
helping to debug daqcard-1200 support.

The 1200 series boards have onboard calibration dacs for correcting
analog input/output offsets and gains.  The proper settings for these
caldacs are stored on the board's eeprom.  To read the caldac values
from the eeprom and store them into a file that can be then be used by
comedilib, use the comedi_calibrate program.

Configuration options:
  none

The daqcard-1200 has quirky chanlist requirements
when scanning multiple channels.  Multiple channel scan
sequence must start at highest channel, then decrement down to
channel 0.  Chanlists consisting of all one channel
are also legal, and allow you to pace conversions in bursts.
