You are probably remembering my driver for the DT2811 "Low Cost
Analog and Digital I/O" board. The driver is for FreeBSD from
about a year ago.
Board specs are:
o 16 single ended / 8 differential 12 bits ananlog inputs
with programmable gains, up to 20 kHz for low gain settings
(2.5 kHz for high gain settings on the DT2811-PGL).
o 2 channels 12 bit D-A;
o 2 channels 8 bit digital (one 8 bit in one 8 bit out).
I no longer have a DT2811 on site and the system it is installed
in is on the other side of the country working for a living.
It should work just fine on the latest release, so I will package
it and leave it in incoming. Just be warned that I won't have
actually TESTED it on the latest release and so it will be up to
the user to ensure it works OK.
Look for it Monday Aug 22 8:00AM EDT in freefall:pub/incoming/dt2811.tgz.
REMEMBER: You can't see files in the incoming directory on freefal
- you'll have to retrieve it blind.
