Nettet2. feb. 2024 · I have written a small example to use LEDC to fade in a led. Worked great.

NettetThe LEDC can be used for generating signals at much higher frequencies that are sufficient enough to clock other devices, e.g., a digital camera module. In this case, the maximum available frequency is 40 MHz with duty resolution of 1 bit. This means that the duty cycle is fixed at 50% and cannot be adjusted. NettetCreate a basic ESP32 LEDC library using C++ with the ESP-IDF in VS Code. The ESP-IDF contains a driver to control LEDs using P ulse W idth M odulation (PWM). PWM works by varying the duty cycle (Pulse Width) of a square wave. In simple terms, PWM turns a signal on and off very quickly. The duty cycle determines how long the signal is on or off.
