PWM Signal
This article is a stub. You can help FIRSTwiki by expanding it.
A PWM signal, pulse-width-modulated signal, is an analog output value used to control motors through Victors or Jaguars.
Programming
On the robot controller, a PWM signal has a range from -127 to 127 in where -127 corresponds to full power “backwards” on the motor and 127 to full power “forwards” on the motor. Some controllers may use a range from -1 to 1 with the same actions occurring at the minimums and maximums of the range. Zero is neutral in both cases and does not move send any current to the motor (though the Victor or Jaguar can change what exactly happens at this signal).
