Actually, comedi (as in the framework) has support for triggered scans.

The command Steve suggested, namely
start_src               TRIG_NOW
scan_begin_src          TRIG_EXT
convert_src             TRIG_TIMER
[...]

is exactly that. Now if the board does support this mode (of which i am not
sure) then it probably wouldn't take much work to change the comedi driver
for the board to make it work.

And i'm not sure software emulation for boards without support for triggered
scans can be done. I tried to do something similar with another board and i
failed.

cheers,
Nils
