Has someone used this doard in RTLinux or some other with the above If you need 2AD and 2DA at 12bit a number of cards can do that - If it can do the sample rate you need depends on the platform you use but 100Ksamp will be close to the limit of an X86 based system in any case, unless you let it sample autonomously and then just pick up the FIFO content periodically (or interrupt driven) if you are looking for ADQ drivers check ftp://ftp.fsmlabs.at/pub/rtlinux/contrib/peterw/ for some drivers and a template to write drivers for new cards - with that template writing a driver is no more than one or two days of work if it is not a very complex card. If you have a new card working you might want to add it to the drivers peter ([EMAIL PROTECTED]) set up. hofrat -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/
