  Re: OS X Complier problems solved--now struggling with BrickOS
 
(...) Hi, First, in terms of my compiler build (referencing your previous post...) what I had a problem with was building the sample C++ code that came with BrickOS. I don't need C++ so I haven't investigated this any further. You're free to try my (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
 
  Re: Varying the output voltage?
 
This is what I noticed, comparing the two systems with BrickOS One thing that I noticed was at the lower voltages the needle on my multimeter wavered around a little and it tended to steady at the higher power levels All of the readings were taken (...)

  OS X Complier problems solved--now struggling with BrickOS
 
Ok, you can (perhaps--I haven't been able to test it yet) ignore my previous post. I was trying to build the cross compiler using GCC 3.3, and nothing I tried would work. When I switched to 3.2.3, the errors disappeared. So I'm making the temporary (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
 
  Cross Compiler for the Mac Os X
 
Has anyone had any luck creating a cross complier for the Mac? I've downloaded Michael Zapp's, but he said it wasn't working for C++. I've been trying to compile my own, but I keep getting errors. Any suggestions or pointers would be greatly (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
 
  Re: Varying the output voltage?
 
(...) Actually there are four, sort of, as for 0 there are float (contacts separated, infinite resistance) and brake (contacts shorted, zero resistance). The standard firmware switches rapidly between on and float (each cycle takes 8ms), which (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
 
  Re: Varying the output voltage?
 
(...) The eight different power level pulsing is called "PWM", translation=Pulse width modulation. PWM is the way a digital chip cheats/mimics true analog without a D/A convertor. Since the only output of a digital chip is on or off, there is no (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
 
  Varying the output voltage?
 
I was wondering if it was possible to control the speed/torque of the motor by varying the output voltage in brickOS. It seems that the speed parameter on the motors only changes the rate at which they pulse on and off. I am looking for something (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
 
  Communication between RCX
 
Hello there, I've wrote a little library who permit you to communicate with RCX easily All information is in the package (URL) (21 years ago, 13-Jun-03, to lugnet.robotics.rcx.legos)
 
  BrickOS Talking to Robolab?
 
Has anyone used BrickOS to talk to Robolab? I really like the Robolab visualization tools and it would be a shame to not be able to fool Robolab into to talking to the BrickOS firmware. I am in the process of designing a simple Fuzzy controller and (...) (21 years ago, 11-Jun-03, to lugnet.robotics.rcx.legos)
