Blinking frequency calculations

WebThe external period or frequency are not measured directly from the timer but is an STM32 computation. Suppose that we setup the TIM with a time base (Time Generator) at 1 KHz, the time resolution is 1 mS (1/1000=0,001). Each time the CAPTURE is triggered, an Interrupt (or callback) is generated which we will use to save the value contained in ...
