====== PWM() ======

''PWM()'' outputs 8-bit or 16-bit PWM on the specified pin.

{{:en-us_commands:reference:pwm.svg?900|PWM command operation flow}}

''void PWM(uint8_t pin, uint16_t val, bool onDutybit16 = false)''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''PWM(pin, val, onDutybit16)'' | ''uint8_t pin''\\ ''uint16_t val''\\ ''bool onDutybit16 = false'' | ''void'' | Outputs 8-bit or 16-bit PWM on the specified pin. |


===== Example =====

<code cpp>
void setup() {
  IpidSet(1, 5.0, 0.5, 1.0, 100, 0, 65535);  // Set PID coefficients, calculation interval and output range.
}

void loop() {
  float pv = ntcReadf(4);  // Return the NTC 3950 10kΩ sensor temperature as a floating-point value in °C.
  float sv = 50.0;
  uint16_t output = (uint16_t)IpidRun(1, pv, sv);  // Calculate the PID output from the current value and setpoint.

  PWM(12, output, true);  // Output 8-bit or 16-bit PWM on the specified pin.
}
</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.
