ESP32 LEDC official libarry

'ledcSetup' was not declared in this scope

If you prefer to use the latest ESP32 core version, you need to update your code to reflect the new LEDC API.

• ledcSetup() and ledcAttachPin() are no longer used.
• You can now use analogWrite(pin, value) for basic PWM, where value is the duty cycle.
• For more advanced control, use ledcAttachChannel(pin, freq, resolution, channel) to attach a pin to a specific PWM channel and then ledcWrite(pin, duty) to set the duty cycle. The channel will be automatically attributed if not specified.

New Code (ESP32 Core >= 3.0.0):

const int LED_PIN = 2;
const int FREQ = 5000;
const int RESOLUTION = 8; // Not directly used in ledcWrite(), but useful for calculating duty cycle

void setup() {
  // Option 1: Use analogWrite for basic PWM
  // analogWrite(LED_PIN, 128); // Sets initial duty cycle

  // Option 2: Use ledcAttachChannel for more control
  ledcAttachChannel(LED_PIN, FREQ, RESOLUTION, 0); // Attaches pin to channel 0
}

void loop() {
  // Option 1: Use analogWrite
  // analogWrite(LED_PIN, 128);
  // delay(1000);
  // analogWrite(LED_PIN, 0);
  // delay(1000);

  // Option 2: Use ledcWrite
  ledcWrite(LED_PIN, 128); // 50% duty cycle for 8-bit resolution
  delay(1000);
  ledcWrite(LED_PIN, 0);
  delay(1000);
}

Old Code (ESP32 Core < 3.0.0):

const int LED_PIN = 2;
const int FREQ = 5000;
const int LED_CHANNEL = 0;
const int RESOLUTION = 8;

void setup() {
  ledcSetup(LED_CHANNEL, FREQ, RESOLUTION);
  ledcAttachPin(LED_PIN, LED_CHANNEL);
}

void loop() {
  ledcWrite(LED_CHANNEL, 128); // 50% duty cycle for 8-bit resolution
  delay(1000);
  ledcWrite(LED_CHANNEL, 0);
  delay(1000);
}
