Hello All, I am using STM32F446xx TIM2 to measure frequency > 1Mhz. I have set TIM2 to external clock and see the counter increment at every rising edge. I am reading this counter value in main function for test. But for highter frequencies over 200Khz to 5Mhz, how do I make this counter data pushed out so I can accurately measure frequency ?
