Issue in capturing Change Frequency

[shrikantkoli1995]

Hi Team,

I am working with s32k344 series.

Description :

If i set the frequency 1Khz and set the duty 20 %,40% and 60% the ICU get this duty and it will visible into the debug window. But at the runtime if i change the frequency from 1Khz to 2khz and then again i will set the duty for the same frequency like 20 %,40% and 60% that time input capture unit capture the wrong duty cycle.

Is their any limitation for input capture unit?

Hi,

there should not be limitation, but check if overflows could not happen on selected counter base. If yes try to modify channel prescaler.
