Joe, Great job on taking the bull by the horns! The following are my suggestions on a system configuration. Please note that the term "divider" is being used here to indicate the function should only be performed every Nth interrupt. OCRA interrupt (...)

So far, I have reconfigured a copy of BrickOS in the following way: 1) Adjusted the clock_handler to improve the accuracy of the sys_time variable. Now running at very close (if not right on) 1 msec per tick. 2) Allowed the FRC (Free-Running (...) (22 years ago, 18-Jan-03, to lugnet.robotics.rcx.legos)

Just got my second RIS, a 1.5 with Serial-Tower this time. I did not installed any other software than the previous I had (Win98, JDK1.3, Lejos 2.0, USB Drivers for Lego-Tower). I have just set RCXTTY=COM1. Problem: when doing a "lejosrun -f (...) (22 years ago, 17-Jan-03, to lugnet.robotics.rcx.java)

|

Nick, What you propose it's another way, and of course, should work, but we might have to create another software layer over the current operating system of the RCX (of course, legOS), and we would loose 1 sensor per RCX. What I was trying to (...) (22 years ago, 17-Jan-03, to lugnet.robotics.rcx.legos)

(...) A friend of mine attempted this setup a while back and came to the conclusion that he basically needed to be nearly perfectly perpendicular to the object he was trying to detect. So he decided this was way to precise/finicky for his general (...) (22 years ago, 17-Jan-03, to lugnet.robotics.rcx)

Dean, Philo, Thank you both very much: Including the sensor monitoring in a "repeat"-loop brouhgt the solution. Works quite perfect. I guess "SendMessage" is somewhat slow, i. e. the IR-emission/reflection. Now I am going to even improve the (...) (22 years ago, 17-Jan-03, to lugnet.robotics.rcx)

I have attached to the end of this message the spyutils.nqh file I've been compiling. It's not got a lot in there yet, just the routines defined as "utility" in the Lego Spybotics ROM SDK plus the SendRCXMessage. I'm aiming toward this file being (...)
