| 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. |
