I'm using the Input Capture of TIM8 to measure the period of a signal. The Timer runs at 16MHz and the MCU (STM32F405) at 144MHz. I'm also using the ICFilter at the moment. The value is set at 0x02. My question is now how ong has to be the signal change to validate an transition?
(1/144MHz)*4 or (1/16MHz)*4?
Thanks for your help
