STM32G0 PWM Calculator
Instantly calculate PSC, ARR, and CCR values for STM32G0 timers and generate precise PWM signals with no guesswork. Simply select your timer, enter the APB clock, desired PWM frequency, and duty cycle — the calculator delivers optimized values and a ready-to-use configuration for STM32CubeIDE or CubeMX.
This tool is designed specifically for the STM32G0 series. Note that timer availability, bus assignments, and maximum clocks can differ on other STM32 families.

Formulas
Timer clk = APB × multiplier
Maximise ARR → best resolution
PSC = ⌊Tclk / (F × (ARR+1))⌋ − 1Maximise ARR → best resolution
CCR = round(ARR × Duty / 100)F_actual = Tclk / ((PSC+1)×(ARR+1))
