What is the minimum/maximum frequencies I can measure with a timer in input capture mode?
2019-02-05
I am using an STM32F303K8T and am trying to use a flow sensor with an output of 15 Hz - 225 Hz.

Thanks Clive. What do you mean by measuring 1/2/4/8 periods? And what is the difference between the prescaler on the TIM and the input prescaler?

Which prescaler are you referring to (128)? I noticed on CubeMX there is an input capture prescaler division ratio and a prescaler PSC in counter settings.

Thanks Clive. What is the point of measuring 1/2/4/8 periods?
