STM32F0 PWM Calculator
Easily determine the PSC, ARR, and CCR values for STM32F0 timers and create precise PWM signals without manual tuning. Choose your timer, provide the APB clock, target PWM frequency, and duty cycle — the tool quickly calculates the optimal settings and generates a ready-to-use configuration for STM32CubeIDE or CubeMX.
This calculator is built specifically for the STM32F0 series. Keep in mind that timer features, bus mappings, and clock constraints may differ across 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))
