analogWrite not work for esp32, using ledc

[0neday]

on esp32, analogWrite function is not avaliable.

// setting PWM properties
const int freq = 5000;
const int ledChannel = 0;
const int resolution = 8;

....

//setup()
  // configure LED PWM functionalitites
  ledcSetup(ledChannel, freq, resolution);
  // attach the channel to the GPIO to be controlled
  ledcAttachPin(LED_Pin, ledChannel);
  pinMode(LED_Pin, OUTPUT);

...
// 
void updateLEDBrightness(int brightness_percentage)
{
#ifdef LED_Pin
#ifdef ESP32
  ledcWrite(ledChannel, (int)brightness_percentage * 255 / 100);
#else
  analogWrite(LED_Pin, (int)brightness_percentage * 255 / 100);
#endif

#endif
}

this will be work fine
