/*
 * 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.
 *
 * NI manuals:
 *   340988a (daqcard-1200)
