How to Generate a PWM Signal on ESP32 Based Platforms Using ESP IDF
Pulse Width Modulation (PWM) is a widely used technique in embedded systems for controlling analog-like behavior using digital signals.
The ESP32 is a versatile microcontroller that includes hardware support for PWM through its LED Control (LEDC) peripheral. Unlike simple timer-based PWM generation found in many microcontrollers, the ESP32’s LEDC peripheral provides high-resolution PWM with multiple channels, making it ideal for driving LEDs, motors, and other actuators in IoT and embedded applications.
