====== PWMOFF() ======

''PWMOFF()'' stops or re-enables PWM output on the specified pin.

{{:en-us_commands:reference:pwmoff.svg?900|PWMOFF command operation flow}}

''void PWMOFF(uint8_t pin, bool POff)''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''PWMOFF(pin, POff)'' | ''uint8_t pin''\\ ''bool POff'' | ''void'' | Stops or re-enables PWM output on the specified pin. |


===== Example =====

This example uses MPINO-16A8R8T PWM output D11 and digital input D22. HIGH on D22 stops PWM; LOW allows it again. This input demonstrates the function and does not replace an equipment emergency-stop device.

<code cpp>
const uint8_t PWM_PIN = 11;

void setup() {
  FDPWM(PWM_PIN, 1000, 50.0F);  // Start 1 kHz PWM at 50% duty on D11.
}

void loop() {
  const bool stopRequest = digitalRead(22) == HIGH;
  PWMOFF(PWM_PIN, stopRequest);  // Stop or allow D11 PWM according to D22.
  if (!stopRequest) FDPWM(PWM_PIN, 1000, 50.0F);  // Apply PWM settings again after allowing the output.
  delay(20);
}
</code>

===== Precautions =====

  * Check product-specific PWM pins and timer sharing.
  * Changing frequency or resolution may also affect other channels on the same timer.
  * Ensure the connected load is safe when stopping or resetting outputs.
