27 | Description: National Instruments PCMCIA DAQCard-700 DIO only | |
28 | Author: Fred Brooks <nsaspook@nsaspook.com>, | |
29 | based on ni_daq_dio24 by Daniel Vecino Castel <dvecino@able.es> | |
30 | Devices: [National Instruments] PCMCIA DAQ-Card-700 (ni_daq_700) | |
31 | Status: works | |
32 | Updated: Thu, 21 Feb 2008 12:07:20 +0000 | |
33 | ||
34 | The daqcard-700 appears in Comedi as a single digital I/O subdevice with | |
35 | 16 channels. The channel 0 corresponds to the daqcard-700's output | |
36 | port, bit 0; channel 8 corresponds to the input port, bit 0. | |
37 | ||
38 | Direction configuration: channels 0-7 output, 8-15 input (8225 device | |
39 | emu as port A output, port B input, port C N/A). | |
40 | ||
41 | IRQ is assigned but not used. | |
