HI, i am doing project on fan controller , i need to measure power factor between my voltage waveform and current waveform which is generated on my CRO. i need to write code to display the powerfactor value. should i use input capture method .

or else do i need to set two GPIO pins as EXTI with rising edge interrupt.i am already generating two waveforms with some dealy . But should i use Input capture method to capture the values at rising edge at each pulse and need to count the number o...

Resolved! Wake up STM32G030K6T from stop mode using wake up pin

I could wake up the controller from stand-by mode but I realized I needed to use stop mode. What needs to happen for the controller to wake up from stop mode when using a wake up pin? Do you have some code examples preferably using the HAL functions?
