(...) No, they aren't problems in your end, and no, they're also not gcc's fault. LegOS uses a now unsupported extension to C: multi-line strings. The way they can be made to work is by inserting \n\ on the end of the offending lines. I did this to (...) (21 years ago, 17-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)
