Hello all:
This is turning into a bigger project than planned.
I am trying to use the tq_timer approach. But I can not get it to compile.
It looks like I must build the whole kernal to create the correct header files.
Right now I am stuck ith "footbridge" undefined. (not sure just what that means
but I am working on it)
Any pointers?
Most of te ts info that I found on the web is a bit dated.
