hello, i'm building a robot with two stepper motors controlled by the parallel port. i am trying to write a device driver for doing this. this driver consists of a bottom half that gets called by the 100Hz clock (tq_timer) and changes the state of the stepper by "outb"-ing some value to the parallel port adress. the top half of the driver gets some coordinate information and converts these to values that should be send to the parallel port byt he bottom half. all very nice in theory, but i don't get the tq_timer to work (i started to try to write something using printk each time the bottom half is called, but nothing happens). therefor my question is:: is there someone who has (or can construct) a small WORKING example of using tq_timer for the 2.4 kernel series? just some code that registers a module and puts a function to tq_timer that writes something out or so. thnx, geert. -- Kernelnewbies: Help each other learn about the Linux kernel.
