pwmWrite

在引脚产生 PWM , 与analogWrite()实际上时一样的

语法

 void pwmWrite(uint8 pin, uint16 duty_cycle16)

参数

• pin 引脚编号

• duty_cycle16 占空比

返回值

无

示例

int analogPin = 3;    
int analogPwm = 2;

void setup() {
  pinMode(analogPwm, OUTPUT);   

  pinMode(analogPin, INPUT_ANALOG); 
}

void loop() {
  int val = analogRead(analogPin);        

  pwmWrite(analogPwm, val * 16);
