Hi, (...) Bummer! I was afraid I might get that answer... :o) (...) Sure, but maybe it would be worth it, since I imagine that many/some of us will make some silly, but basic routine that cycles between float/stop and some motor power, anyway... (...)

(...) 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)

Hi Paul, (...) Hmmm... can you please post your code for that? I tried it this weekend (I found it here: (URL) but I couldn't quite get it to work. Did you activate the sensor? Regards, Martin (23 years ago, 24-Sep-01, to lugnet.robotics.rcx.java)

Well. Sixth time lucky maybe. I was trying to say this (it is part of leJOS 1.0.3.beta2): package josx.platform.rcx; /** * A 'sensor' to detect object proximity. Sends a short * message out of the infra-red port every so often and looks for * the (...) (23 years ago, 29-Sep-01, to lugnet.robotics.rcx.java)
