http://bu3sch.de/patches/misc/emc-on-linux-rt.patch http://bu3sch.de/patches/misc/emc-port-hal-parport.patch This enables hal-parport via raw userspace I/O (I don't really like it, but it's good enough for now. I'm going to check if we can use /dev/parport. It's very optimized kernel code and I already used it for other highspeed stuff. In my tests it was not slower than raw I/O). It doesn't seem to work that bad with my one-axis testboard. If the computer is not used otherwise, it's actually pretty good for starters ;) -- Greetings, Michael. ------------------------------------------------------------------------------ Come build with us!
