http://demo-dijiudu.readthedocs.io/en/latest/api-reference/peripherals/ledc.html 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.

Nettet6. mai 2024 · When trying to modify the examples to fade over a long time I get a stepping effect on the low levels of light, about 0-100. The resolution of the PWM is too coarse. This is a hardware problem because the arduino PWM is integer based. You have to change your hardware and use Mosfets to sink the current and use the PWM to drive the mosfets. NettetThe LED control (LEDC) peripheral is primarily designed to control the intensity of LEDs, although it can also be used to generate PWM signals for other purposes. It has 16 channels which can generate independent waveforms that can be used, for example, to drive RGB LED devices. LEDC channels are divided into two groups of 8 channels each.
