Ok, here are some results of my investigation: - There is no general 8ms cycle - When you change motor settings they become effective on the next timer interrupt (occurs every ms), and the rotating pattern for a reduced powerlevel starts anew, (...)

| | | | Here is an interesting paper on using NQC to control motor speed. A similar technique could be used in leJOS: (URL) paper has lots of interesing ideas in it besides motor speed control. My favourite being the proximity sensor which I have remodelled (...) (23 years ago, 24-Sep-01, to lugnet.robotics.rcx.java)
