29 | Driver: ni_labpc_cs | |
30 | Description: National Instruments Lab-PC (& compatibles) | |
31 | Author: Frank Mori Hess <fmhess@users.sourceforge.net> | |
32 | Devices: [National Instruments] DAQCard-1200 (daqcard-1200) | |
33 | Status: works | |
34 | ||
35 | Thanks go to Fredrik Lingvall for much testing and perseverance in | |
36 | helping to debug daqcard-1200 support. | |
37 | ||
38 | The 1200 series boards have onboard calibration dacs for correcting | |
39 | analog input/output offsets and gains. The proper settings for these | |
40 | caldacs are stored on the board's eeprom. To read the caldac values | |
41 | from the eeprom and store them into a file that can be then be used by | |
42 | comedilib, use the comedi_calibrate program. | |
43 | ||
44 | Configuration options: | |
45 | none | |
46 | ||
47 | The daqcard-1200 has quirky chanlist requirements | |
48 | when scanning multiple channels. Multiple channel scan | |
49 | sequence must start at highest channel, then decrement down to | |
50 | channel 0. Chanlists consisting of all one channel | |
51 | are also legal, and allow you to pace conversions in bursts. | |
