Owning Palette: Pulse Width Modulation VIs

Requires: myRIO Toolkit

Sets the duty cycle value and frequency value of a pulse width modulation (PWM) signal.

PWM Ref In specifies the reference to the PWM channel. Use the Open VI to open a reference to the PWM channel. Do not modify the PWM Ref In values.
Duty Cycle specifies the percentage of time the PWM signal remains high over one PWM cycle. Valid values must be within the range [0, 1].
Frequency specify the frequency of the PWM signal in hertz. Frequency must be within the range of 40 Hz to 40 kHz.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
PWM Ref Out returns the reference to the PWM channel that you specify.
error out contains error information. This output provides standard error out functionality.
