/*
* 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.
*

* 340988a (daqcard-1200)
