STM32 PWM Calculator Online Tool
This STM32 PWM Calculator Tool Will Help You Automate The Calculation Process For Selecting The Suitable ( ARR & PSC ) register values To Generate PWM Output Signals With any STM32 microcontroller hardware timer.
In PWM Frequency Control Mode, you can set your desired FPWM and duty cycle. Given your system clock rate, the calculator will give you the ARR and prescaler PSC values needed to get this desired PWM output frequency. It’ll also tell you what will be the PWM resolution at that output frequency.

In PWM Resolution Control Mode, you can set your desired PWM resolution (discrete levels of control over the duty cycle) by entering that ARR value. The calculator will give you the corresponding PWM output frequency (FPWM) at that ARR & PSC values. Let's say you'd like to send an ADC's reading directly to control a PWM output. Given that a 12-bit ADC reading will be 4095 at maximum, we can set the ARR to that value. Therefore, the PWM resolution will also be 12-Bits and the output PWM frequency will be given using this calculator tool.
To better understand what this tool does and how to use the generated ARR & PSC register values in practical STM32 PWM example projects, it's highly recommended to check out the tutorial linked below for more information about STM32 PWM and its various operating modes & configurations.
