Issue in capturing Change Frequency

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?

Regards,

Shrikant K

Hi,

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

BR, Petr
