- * Driver: adv_pci1723
- * Description: Advantech PCI-1723
- * Author: yonggang <rsmgnu@gmail.com>, Ian Abbott <abbotti@mev.co.uk>
- * Devices: [Advantech] PCI-1723 (adv_pci1723)
- * Updated: Mon, 14 Apr 2008 15:12:56 +0100
- * Status: works
- *
- * Configuration Options: not applicable, uses comedi PCI auto config
- *
- * Subdevice 0 is 8-channel AO, 16-bit, range +/- 10 V.
- *
- * Subdevice 1 is 16-channel DIO. The channels are configurable as
- * input or output in 2 groups (0 to 7, 8 to 15). Configuring any
- * channel implicitly configures all channels in the same group.
- *
- * TODO:
- * 1. Add the two milliamp ranges to the AO subdevice (0 to 20 mA,
- * 4 to 20 mA).
- * 2. Read the initial ranges and values of the AO subdevice at
- * start-up instead of reinitializing them.
- * 3. Implement calibration.
