| * Driver: adl_pci7x3x |
| * Description: 32/64-Channel Isolated Digital I/O Boards |
| * Devices: [ADLink] PCI-7230 (adl_pci7230), PCI-7233 (adl_pci7233), |
| * PCI-7234 (adl_pci7234), PCI-7432 (adl_pci7432), PCI-7433 (adl_pci7433), |
| * PCI-7434 (adl_pci7434) |
| * Author: H Hartley Sweeten <hsweeten@visionengravers.com> |
| * Updated: Thu, 02 Aug 2012 14:27:46 -0700 |
| * Status: untested |
| * |
| * One or two subdevices are setup by this driver depending on |
| * the number of digital inputs and/or outputs provided by the |
| * board. Each subdevice has a maximum of 32 channels. |
| * |
| * PCI-7230 - 2 subdevices: 0 - 16 input, 1 - 16 output |
| * PCI-7233 - 1 subdevice: 0 - 32 input |
| * PCI-7234 - 1 subdevice: 0 - 32 output |
| * PCI-7432 - 2 subdevices: 0 - 32 input, 1 - 32 output |
| * PCI-7433 - 2 subdevices: 0 - 32 input, 1 - 32 input |
| * PCI-7434 - 2 subdevices: 0 - 32 output, 1 - 32 output |
| * |
| * The PCI-7230, PCI-7432 and PCI-7433 boards also support external |
| * interrupt signals on digital input channels 0 and 1. The PCI-7233 |
| * has dual-interrupt sources for change-of-state (COS) on any 16 |
| * digital input channels of LSB and for COS on any 16 digital input |
| * lines of MSB. Interrupts are not currently supported by this |
| * driver. |
| * |
| * Configuration Options: not applicable, uses comedi PCI auto config |
