| Steve, I checked in some changes this morning (into cvs) to put the motor controller back at the 1 ms interval. However, I want to complete the get_sys_time() updates that Mark Riley has proposed; so that can be tested as well. I am not sure when (...) (22 years ago, 13-Dec-02, to lugnet.robotics.rcx.legos)
