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)

| | 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)
