So at the beginning of the loop we will fix the frequency.ledcAttachPin(16,3); ledcWrite(3,5833); delay(1000); ledcDetachPin(16); with B I do have to reattach t he pin with every call, but does it use less memory or power ... Buzzer This set took all the free GPIO of the ESP32 controller, there is not a single pin left to which you could connect something of your own. But looking at what Kincony engineers have installed on the KC868-A4 board, you can say that they have a fairly balanced solution for small projects and the purpose of learning to program microcontrollers.ledcAttachPin (12, channel); } Now we are going to move to the main loop function, where we will experiment with our buzzer by changing the frequency and duty cycle configurations. The first value we will vary is the duty cycle. So at the beginning of the loop we will fix the frequency.PWM used to generate analog signals to drive servos or buzzers,etc. ledcSetup() Syntax: void ledcSetup(uint8_t channel, double freq, uint8_t resolution_bits) Description:Set the PWM channel, frequency and resolution. ledcAttachPin() Syntax: void ledcAttachPin(uint8_t pin, uint8_t channel)PWM used to generate analog signals to drive servos or buzzers,etc. ledcSetup() Syntax: void ledcSetup(uint8_t channel, double freq, uint8_t resolution_bits) Description:Set the PWM channel, frequency and resolution. ledcAttachPin() Syntax: void ledcAttachPin(uint8_t pin, uint8_t channel) The LED control (LEDC) peripheral is primarly designed to control the intensity of LEDs, although it can also be used to generate PWM signals for other purposes. ESP32 SoCs has from 6 to 16 channels (variates on socs, see table below) which can generate independent waveforms, that can be used for example to drive RGB LED devices.
