🧮 ESP32 PWM (LEDC) resolution calculator

See exactly how the ESP32 LEDC peripheral trades PWM frequency against duty resolution. Pick a clock source and either drag a target frequency (to see the max usable resolution) or a bit depth (to see the max frequency). The SVG shows the PWM waveform with a staircase overlay whose step count reflects available duty levels — coarse at high frequency, smooth at low.
