WebFor ESP32, MicroPython allows you to specify PWM frequency from 1KHz to 40 MHz. The duty cycle resolution can be from 1 bit to 16 bits. To avoid any errors in PWM generation, first determine the desired duty cycle resolution. Higher will be the duty cycle resolution, more precisely, output voltage levels could be controlled. WebDe arbeidscyclus (Engels: duty cycle) van een periodiek optredend verschijnsel is de verhouding van de tijd dat het verschijnsel aanwezig (actief) is en de totale periode. Meestal wordt deze verhouding uitgedrukt als percentage. [1] [2] [3] De arbeidscyclus kan als een formule worden uitgedrukt als: [2]
