| (...) I could not repeat your experiment exactly because I don’t have a joy stick. So instead I wrote a pair of programs that send single byte messages between the PC and the RCX. The RCX adds 1 to the incoming byte and immediately send it back. The (...)

| Hi Daniel, (...) you can do more levels by something like the Bresenham algorithm, i.e. for speed 4.5 you turn it on for 4ms and 5ms of the 10ms alternatively. Though 10 levels should normally suffice, the standard LEGO train controller has fewer (...) (22 years ago, 9-Jul-04, to lugnet.robotics.rcx.java)

| (...) The simple answer is "maybe"! If you have one handy, try it. I'm not sure whether the RCX will cope with a capacitive load rather than an inductive one, so I would advise you not to put the capacitor across the RCX output without a motor in (...)

| (...) hi Juergen I tried it with load, and it works much better! Only that the speed is not very stable in the curves. (...) If i use a cycle of 10ms, then i could only use 10 different speeds, because the Thread.sleep has a resolution of 1ms... (...) (22 years ago, 8-Jul-04, to lugnet.robotics.rcx.java)
