Hi, I'm going to start developing a driver for the above mentioned board (see $SUBJECT). The board offers 96 Digital I/O lines, grouped into 4 8255-compatible groups. The first thing that came to my mind was writing the driver so as to use 4 8255 subdevices (using the code in 8255.c much like is already done in ni_pcidio.c), which should work OK as far as DIO is concerned. What I was thinking about is: this board also supports interrupt generation (on state change, rising/falling edge and even pattern matching depending on the port number). What would be a clean way to support all these features? TIA. Matteo Giani - matgiani_at_ctonet.it
