PWMOff for AVR

Syntax:

  PWMOff

Command Availability:

This command is only available on the Atmel AVR microcontrollers with a Timer/Counter0 OC0B register.

Explanation:

The PWMOff command will only disable the output of the OC0B/PWM module of the Atmel AVR microcontrollers.

This command is not available for any other OCnx/PWM modules.

Example:

    'This program demonstrates the PWMOn and PWMOff commands
    'of the fixed mode HPWM on OC0B pin.

    #chip mega328p,16

    'activate appropriate PWM output pins
    dir PortD.5 Out     'OC0B

    'define PWM_Freq in kHz
    'define PWM_Duty in %

    #define PWM_Freq 40
    #define PWM_Duty 50

    do

      'turn on/off single channel 40 KHz PWM on OC0B pin
      PWMON
      wait 5 s
      PWMOFF          ' <<< the PWMOff instruction
      wait 5 s

    loop

Key line: PWMOFF — immediately disables the OC0B PWM output; the pin stops toggling until PWMON is called again.
