See the functions, parameters, examples and notes for LEDC API. Apr 22, 2025 · ESP32 PWM using LEDC peripheral (ESP-IDF) The LED Control (LEDC) peripheral on the ESP32 is a powerful tool for generating Pulse Width Modulation (PWM) signals, ideal for applications like LED dimming and motor control. Most ESP32 GPIOs can be configured with the LEDC (LED Control) peripheral which allows to generate PWM signals to control an LED’s brightness or any other output devices that require a signal with duty cycle and frequency control. Only a few gpio pins are exposed and usable, but by using I²C you could use a MCP23017 module to add additional ports. Hardware Setup Connect an LED to pin D2 with a current-limiting resistor in series. Refer to the LEDC API documentation for more details. This is a Bluetooth differential drive car controlled by a PS5 Apr 10, 2024 · The XIAO ESP32-C6 has 6 LEDC channels that can generate independent waveforms, which can be used, for example, to drive RGB LED devices.
