• Function:

  magician.set_pwm(io, freq, cycle)
  

• Description: set frequency and duty cycle of PWM output port

• Required parameter:

  • io: io port number, data type: str, range: "DO_01"~"DO_20"
  • freq: PWM frequency, scope: 10Hz~1MHz
  • cycle: duty cycle, scope: 0~100

• Return:
  • True: The command has been finished.
  • False: The command has not been finished.

• Example

  magician.set_pwm(io="DO_01", freq=10, cycle=30)
  

  Set PWM frequency of DO_01 port as 10Hz, and duty cycle as 30%.
