| 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. |
