OpenCR入门教程-开发示例-PWM

说明

• 本教程介绍OpenCR板上Arundin引脚的PWM输出测试示例

代码

• OpenCR与Arduino Uno具有相同的引脚配置，PWM输出也映射到同一端口

• 因此，analogWrite用于将PWM占空比输出到相应的端口

• 分辨率为8位，从0到255，频率为50 KHz

 //This is an example of PWM output on all six pins.

int pwm_pins[6] = { 3, 5, 6, 9, 10, 11 };

void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
  int i;
  static uint8_t pwm_out = 0;

  for( i=0; i<6; i++ )
  {
    analogWrite(pwm_pins[i], pwm_out++);
  }
  delay(100);
}
