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. |
