-CHANGELOG:
-
-2005/02/17 Extend AI streaming capabilities. Now, scan_begin_arg can be
-a multiple of chanlist_len*convert_arg.
-2002/02/19 Fixed the two's complement conversion in pci9111_(hr_)ai_get_data.
-2002/02/18 Added external trigger support for analog input.
-
-TODO:
-
- - Really test implemented functionality.
- - Add support for the PCI-9111DG with a probe routine to identify
- the card type (perhaps with the help of the channel number readback
- of the A/D Data register).
- - Add external multiplexer support.
