Hi,

I need to use the STM32 to perform frequency measurement in the range of 1MHZ to 6MHZ.

I'm a bit lost with the way timers work in the STM32 (the timers user manual is daunting, at least for me).

Any suggestion or guidance is welcome :D

Thanks,

Richard

Hi Richard,

Try to look at the PWM_Input example from the STM32F10xFWLib, it shows how to use the TIM peripheral to measure the frequency and duty cycle of an external signal.

You can find it under the directory: FWLib\examples\TIM\PWM_Input.

Good luck!
