BricxCC is a lot of fun to support - fixing bugs, adding useful new features, and answering lots of questions via email. I hope to be able to continue working with BricxCC for a very long time to come. But it does take time. And software development (...)

| | Accurate Timing
|
|
Hello! I just started using brickOS and am trying to use it as a programmable function generator. As such, I'm trying to get good repeatability on cycle time. It appears that at 'random' times, the RCX scheduler(?) is interrupting my program to do (...) (22 years ago, 28-Feb-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

(...) That's interesting. On my new XP eMachine PC we have noticed that when we shutdown (and it powers off the PC) that we have to switch the power switch on the power strip that our computer plugs into or it will sometimes hold our phone line open (...)

(...) I had the opposite problem. It worked fine, but whenever I powered off my system the green light came on and stayed on. (2 URLs) I never did figure out the problem. Now I have a USB tower, and that works fine (plus no batteries needed). Brian (...) (22 years ago, 27-Feb-03, to lugnet.robotics.rcx)

(...) As yet, me, re my Serial/IR Tower Green LED being stuck On, I know very little coherent & new. a) I did try searching for the word "green" in: (URL) results seemingly confirm that "everyone knows" the green LED should light only when used. b) (...)

|
|
Hi, my name is Paolo Gai, and I would like to inform you that we just published another firmware replacement for the Lego Mindstorms RCX. The software is written from scratch and distributed under the GPL license, and includes: - support for motors (...) (22 years ago, 26-Feb-03, to lugnet.robotics.rcx)

(...) Any word on whether you have discovered that the power management settings of the OS have any effect on the geen light situation? I haven't had a chance to play with my serial tower on my XP desktop PC yet. John Hansen (22 years ago, 26-Feb-03, to lugnet.robotics.rcx)

Hi Gabriel, your program hit an exception. The code is explained very briefly at the beginning of the README: -- Exceptions: Use lejos -verbose. Exceptions are shown in the RCX as [XXXX Y], where XXXX = method_signature, and Y = (...) (22 years ago, 25-Feb-03, to lugnet.robotics.rcx.java)

Hi everyone, I’m a new Lego Mindstorms user and I’m starting with leJOS version 2.1.1 and a j2SDK 1.4.1 platform. I have already made a simple line follower robot with only 1 light sensor. The code was really simple and I use a listener to make it (...) (22 years ago, 25-Feb-03, to lugnet.robotics.rcx.java)

I doubt that this is the cause of your problems, but the first XP version had very flimsy drivers for some motherboards USB host controllers. Maybe a Windows Update or similar might help ? Philo www.philohome.com (...) (22 years ago, 23-Feb-03, to lugnet.robotics.rcx)

|
|
Hi, I'm trying to get my USB tower to work with XP. So far I had no luck. I followed the instructions on www.mindstroms.com but it doesn't work. Windows XP simply sits there and reports the USB tower as an "unknown device". Doesn't matter if I (...) (22 years ago, 23-Feb-03, to lugnet.robotics.rcx)

In summary, I think now we say: Anyone interested enough to go see if their Win XP experience matches with/ differs from mine?

(...) That the light stays on during Windows Suspend suggests to me that it has something to do with the power management features of your laptop. Try temporarily turning off the power management option and see if the tower behaves differently. I (...) (22 years ago, 22-Feb-03, to lugnet.robotics.rcx)

Just yesterday I reinstalled my serial IR Tower on a Win 98 machine and had the green light stay on all the time. It turned out to be an issue of 'port confusion'. When I switched ports (put the tower on COM1 and the other device on COM2) the (...) (22 years ago, 22-Feb-03, to lugnet.robotics.rcx)

I have a nasty feeling this a "facility" in windows at work here. I have noted that the "classic" ports (serial i/o and parallel) "jabber" when windows doesn't think they are in use. My suspicion is that there is some kind of a legacy port plug and (...) (22 years ago, 21-Feb-03, to lugnet.robotics.rcx)

(...) If your green light is on all the time I am amazed that you are successful with any communication. Do you need to do the "open the port and wait 5 seconds" procedure to get RIS, javax.comm, and nqc to work? Something BIOS or hardware-related (...) (22 years ago, 21-Feb-03, to lugnet.robotics.rcx)

(...) By now I have two more clues: 1) Not only does powering down the PC or booting Linux turn the light Off, but so likewise does a Windows Hibernate. 2) Leaving the port open and unused turns the light Off only until I try a Windows Suspend.
