- class wpilib.DutyCycle(source: wpilib._wpilib.DigitalSource)¶
Class to read a duty cycle PWM input.
PWM input signals are specified with a frequency and a ratio of high to low in that frequency. There are 8 of these in the roboRIO, and they can be attached to any DigitalSource.
These can be combined as the input of an AnalogTrigger to a Counter in order to implement rollover checking.
Constructs a DutyCycle input from a DigitalSource input.
This class does not own the inputted source.
source – The DigitalSource to use.
- getFPGAIndex() int ¶
Get the FPGA index for the DutyCycle.
the FPGA index
- getFrequency() int ¶
Get the frequency of the duty cycle signal.
frequency in Hertz
- getOutput() float ¶
Get the output ratio of the duty cycle signal.
0 means always low, 1 means always high.
output ratio between 0 and 1
- getOutputRaw() int ¶
Get the raw output ratio of the duty cycle signal.
0 means always low, an output equal to GetOutputScaleFactor() means always high.
output ratio in raw units
- getOutputScaleFactor() int ¶
Get the scale factor of the output.
An output equal to this value is always high, and then linearly scales down to 0. Divide the result of getOutputRaw by this in order to get the percentage between 0 and 1.
the output scale factor
- getSourceChannel() int ¶
Get the channel of the source.
the source channel
