28 Description: Adlink PCI-9111HR
29 Author: Emmanuel Pacaud <emmanuel.pacaud@univ-poitiers.fr>
30 Devices: [ADLink] PCI-9111HR (adl_pci9111)
39 - ai_do_cmd mode with the following sources:
42 - scan_begin_src TRIG_FOLLOW TRIG_TIMER TRIG_EXT
43 - convert_src TRIG_TIMER TRIG_EXT
44 - scan_end_src TRIG_COUNT
45 - stop_src TRIG_COUNT TRIG_NONE
47 The scanned channels must be consecutive and start from 0. They must
48 all have the same range and aref.
50 Configuration options:
52 [0] - PCI bus number (optional)
53 [1] - PCI slot number (optional)
55 If bus/slot is not specified, the first available PCI
63 2005/02/17 Extend AI streaming capabilities. Now, scan_begin_arg can be
64 a multiple of chanlist_len*convert_arg.
65 2002/02/19 Fixed the two's complement conversion in pci9111_(hr_)ai_get_data.
66 2002/02/18 Added external trigger support for analog input.
70 - Really test implemented functionality.
71 - Add support for the PCI-9111DG with a probe routine to identify
72 the card type (perhaps with the help of the channel number readback
73 of the A/D Data register).
74 - Add external multiplexer support.
