Does anyone know how I can get leJOS mentioned in the Links and Resources section of the lugnet.robotics.rcx.java homepage? Thanks, (25 years ago, 27-Sep-01, to lugnet.robotics.rcx.java)

I suspect this is due to the fact that the first sample from the sensor is actually being obtained while the sensor's reservoir capacitor is still charging. Why don't you try a simple test, actually two tests; 1. Initialise as passive sensor Wait 1 (...) (25 years ago, 27-Sep-01, to lugnet.robotics.rcx.java)

|

Hellow! Here a little fact: the first reading on the light sensor _just_ after you have activated it is too high. It seems like one has to wait a little after activating the sensor. The following program shows it rather nicely: ____START OF CODE____ (...) (25 years ago, 27-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 (25 years ago, 24-Sep-01, to lugnet.robotics.rcx.java)

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 (...) (25 years ago, 24-Sep-01, to lugnet.robotics.rcx.java)

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, (...)
