hi
i work with stm32f107
pleas answer me
how i can measure frequency in 50 hz with input pwm
i read about it and find out i can measure frequency with input pwm up to 1100 but input pwm have TIM_ICPrescaler that i think devide pwm frequncy
it is true ?
if no , please say me how i can measure 50 hz?
For low speeds you'd need to configure the timebase to run slower so the ticks in the period you are measuring don't exceed the 16-bit counter's limit.
Use the timebase prescaler to divide down the SystemCoreClock
yes
I did this work but was like befor , it didn't has effect.
