WebMar 31, 2024 · The problem & solution. For a time based interrupt using the internal clock of a timer finding the right PSC and ARR values for a given interrupt interval (or frequency) can be quite difficult. Since EVENT_FREQUENCY = TIM_CLK / ( (PSC+1) * (ARR+1) ) finding the correct PSC and ARR values for a given EVENT_FREQUENCY is solving the equation: WebSTM32 Basic Timer in Interrupt & PWM mode.

"WebTimer Overview. Typically most STM32 timers consist of a 16-bit auto reload counter and a 16-bit prescaler. The prescaler is responsible for dividing the incoming clock signal from a clock source as per our need. The auto-reload counter is loaded just we used to load timer registers of 8-bit MCUs.
