PWM Calculator

Calculate timer pre-scalers and period registers for precise PWM generation. Visualize the resulting waveform and verify resolution for your target frequency.

Configuration

Timer Clock (after prescaler)

Target Frequency

Duty Cycle 50%

Signal Analyzer

ARR (Period) 0 Counts

CCR (Pulse) 0 Counts

Resolution 0.0 Bits

Note: Calculation assumes Up-Counting Mode where ARR = (TimerFreq / TargetFreq) - 1.
