Yes write C code to do it - the sysfs thing doesn't exist in the 2.4
kernel, so how do you think others did it?
Learn how to access the memory mapped IO space, then you can access most
simple IO from userspace - Technologics documentation give you the
addresses to use etc. TS actually provide some userspace example code for
accessing some of interfaces - e.g. LCD. The archives of this group are
full of threads dealing with this.
I've written a program adio that provides general purpose access, and it's
GPL'd so you get the source code.
