  Cross-machine cross-compiling
 
No matter how hard I try - or how many different "this is how to do legOS under Win32" web sites I visit - I cannot get legOS and its associated cross-compiler to build. The stuff from brickOS dies during the make process because of "missing" (...) (22 years ago, 2-Oct-02, to lugnet.robotics.rcx)
 
  Re: Watch Dog Timer on the H8 - Working!
 
Well, after browsing through the H8 reference another, oh 20 (?), times; and some messing around; it is now working. Basically, I had declared the Control Status Register as an 8 bit value. Since this is a special register (8 bit) that requires a 16 (...) (22 years ago, 28-Sep-02, to lugnet.robotics.rcx)
 
  Watch Dog Timer on the H8
 
Has anyone been able to make use of the Watch Dog Timer on the RCX? The H8 documentation seems to spell out the workings quite well. BrickOS (LegOS) has minimal support (a vector is declared for both NMI and overflow) and pbForth files list the WDT (...)

  Re: Automatic RCX Battery Recharging
 
Yes, the object is to have the RCX robot monitor its own battery charge (something available to the RCX firmware, and lejos, etc..) and then when it is consistently low to drive up to some sort of home made charging station and get a boost. The (...) (22 years ago, 26-Sep-02, to lugnet.robotics.rcx)
 
  Re: Automatic RCX Battery Recharging
 
Hello, (...) The only problem with that is that you will have to guarantee a max. voltage of 9 or 10 V at the RCX. I don't think usual charging circuits have a voltage limit that makes sense ... Greetings Horst (22 years ago, 23-Sep-02, to lugnet.robotics.rcx)

  Re: Automatic RCX Battery Recharging
 
In order to protect the RCX from any type of power problems, would it make sense to disconect the RCX from the batteries first and have it run from an alternate power supply? or would this make it too complicated? I know little about electronics, is (...) (22 years ago, 24-Sep-02, to lugnet.robotics.rcx)

In lugnet.robotics.rcx, Brian Bagnall writes: <snip> Are you are talking about chagring batteries while they are in the RCX? If so, what about the heat.

  Re: Automatic RCX Battery Recharging
 
I agree that there are much faster charging methods, but the slow one has the advantage of simplicity (this was implied in the original question)... I wonder too how to design a connector with contacts that reliably carry 4 to 10 A currents and (...) (22 years ago, 23-Sep-02, to lugnet.robotics.rcx)
 
  Re: Automatic RCX Battery Recharging
 
(...) Yes Brian, and read my P.S. ;-) (...) This is not necessairly true. If you use the right charge method, load time less then 15 minutes, without degrading the batteries (even with positiv effect on the lifetime/capacity) is very well possible (...)

  Automatic RCX Battery Recharging
 
Some of us on the leJOS mailing list were discussing auto-battery recharging with the RCX. Here's some technical thoughts from Philipe Hurbain that might be useful to others. p.s. If anyone has anything to add to this please do. -*-*-*-*-*- I think (...) (22 years ago, 23-Sep-02, to lugnet.robotics.rcx)
 
  How much current from RCX ports
 
I see around here, people are playing around with diffrent types of things to put on the RCX output port. Like not orginal lights, motors, bells and so on. Some even puts several motors on one port. How much current can you drain from one RCX port? (...) (22 years ago, 19-Sep-02, to lugnet.robotics.rcx)

  RCX bell like sound
 
Hello, Is there a way to make the RCX make the sound of ringing bell, such as heard at a level train crossing? If you could point me in the right direction, that would be appreciated. Thanks Michel Magnan (22 years ago, 18-Sep-02, to lugnet.robotics.rcx)

just what is an RCX simulator? is it a virtual brick that resides on your computer? -tk (22 years ago, 16-Sep-02, to lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

thanks Ralf, this may be a very good starting point ;-) I'm considering to create a RCX simulator (if there isn't any), but cann't oversee how much work it is .... cheers, Stef Mientki (...) (22 years ago, 13-Sep-02, to lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)
