How this service works
STM32 timer and PWM calculation service
Output
Returns computed STM32 timer register values including prescaler (PSC), auto-reload register (ARR), and capture/compare register (CCR) values that will produce the requested timer frequency and PWM duty cycle on the target STM32 device, given the input clock frequency.
Example use cases
Servo motor PWM configuration
“I'm driving a servo motor with an STM32F103 running at 72MHz and I need a 50Hz PWM signal with a pulse width of 1.5ms — can you calculate the correct PSC, ARR, and CCR register values for me?”
LED dimming with precise duty cycle
“I want to dim an LED using STM32 PWM at 10kHz with exactly 40% duty cycle, my timer clock is 48MHz — what prescaler, auto-reload, and compare register values should I use?”
Motor driver PWM frequency tuning
“My STM32G0 peripheral clock is 64MHz and I need to drive a motor controller at 20kHz PWM — calculate the PSC and ARR values I need, and the CCR for 60% duty cycle.”
Technical details
Endpoint
POSThttps://api.rocads.com.mx/v1/embedded/stm32/timer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly and accurately compute STM32 hardware timer register values without manually doing the integer arithmetic or risking off-by-one errors. Ideal for embedded developers who know their desired PWM frequency and duty cycle but want the exact PSC, ARR, and CCR values calculated automatically for a given STM32 peripheral clock speed.
Side effects
- Invalid or out-of-range clock frequency causing division-by-zero or overflow in register calculation
- Requested frequency not achievable with 16-bit or 32-bit timer limits — returns error or nearest approximation
- Missing required input fields such as clock frequency or target frequency
- Duty cycle out of 0–100% range returns validation error
- Prescaler or ARR exceeding maximum register width for specified timer type
