-Driver: adl_pci9118
-Description: Adlink PCI-9118DG, PCI-9118HG, PCI-9118HR
-Author: Michal Dobes <dobes@...net.cz>
-Devices: [ADLink] PCI-9118DG (pci9118dg), PCI-9118HG (pci9118hg),
- PCI-9118HR (pci9118hr)
-Status: works
-
-This driver supports AI, AO, DI and DO subdevices.
-AI subdevice supports cmd and insn interface,
-other subdevices support only insn interface.
-For AI:
-- If cmd->scan_begin_src=TRIG_EXT then trigger input is TGIN (pin 46).
-- If cmd->convert_src=TRIG_EXT then trigger input is EXTTRG (pin 44).
-- If cmd->start_src/stop_src=TRIG_EXT then trigger input is TGIN (pin 46).
-- It is not necessary to have cmd.scan_end_arg=cmd.chanlist_len but
- cmd.scan_end_arg modulo cmd.chanlist_len must by 0.
-- If return value of cmdtest is 5 then you've bad channel list
- (it isn't possible mixture S.E. and DIFF inputs or bipolar and unipolar
- ranges).
-
-There are some hardware limitations:
-a) You cann't use mixture of unipolar/bipoar ranges or differencial/single
- ended inputs.
-b) DMA transfers must have the length aligned to two samples (32 bit),
- so there is some problems if cmd->chanlist_len is odd. This driver tries
- bypass this with adding one sample to the end of the every scan and discard
- it on output but this cann't be used if cmd->scan_begin_src=TRIG_FOLLOW
- and is used flag TRIG_WAKE_EOS, then driver switch to interrupt driven mode
- with interrupt after every sample.
-c) If isn't used DMA then you can use only mode where
- cmd->scan_begin_src=TRIG_FOLLOW.
-
-Configuration options:
- [0] - PCI bus of device (optional)
- [1] - PCI slot of device (optional)
- If bus/slot is not specified, then first available PCI
- card will be used.
- [2] - 0= standard 8 DIFF/16 SE channels configuration
- n = external multiplexer connected, 1 <= n <= 256
- [3] - 0=autoselect DMA or EOC interrupts operation
- 1 = disable DMA mode
- 3 = disable DMA and INT, only insn interface will work
- [4] - sample&hold signal - card can generate signal for external S&H board
- 0 = use SSHO(pin 45) signal is generated in onboard hardware S&H logic
- 0 != use ADCHN7(pin 23) signal is generated from driver, number say how
- long delay is requested in ns and sign polarity of the hold
- (in this case external multiplexor can serve only 128 channels)
- [5] - 0=stop measure on all hardware errors
