hi, i am new to stm32, i am doing a project on fan controller module, i need to measure the powerfactor of zero crossing of my current and voltage waveform displaying on CRO. firstly i need to select two channels for input capture to capture values

on those rising edge with interrupt and i need to count each time.secondly i need to use another timer and set its frequency to 100KHZ with interrupt mode. i need to use counter to count at each interrupt. thirdly based on that counter i need to cal...
