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.
35 *
