Class to write to digital outputs.
Write values to the digital output channels. Other devices implemented elsewhere will allocate channels automatically so for those devices it shouldn't be done here.
void frc::DigitalOutput::EnablePWM |
( |
double |
initialDutyCycle | ) |
|
Enable a PWM Output on this line.
Allocate one of the 6 DO PWM generator resources from this module.
Supply the initial duty-cycle to output so as to avoid a glitch when first starting.
The resolution of the duty cycle is 8-bit for low frequencies (1kHz or less) but is reduced the higher the frequency of the PWM signal is.
- Parameters
-
initialDutyCycle | The duty-cycle to start generating. [0..1] |
