MPC5744P eTimer1 can be used for measuring the frequency？

[qinxk]

Dear，

would you please tell me if eTimer1 also can be used for capturing the PWM signals ?

If yes, how?

ASAP!

Hi,

yes, it can. Each channel supports capture feature.
Some example can be found on https://community.nxp.com/t5/MPC5xxx-Knowledge-Base/Example-MPC5744P-eTimer-frequency-measurement-GH...

BR, Petr

ok, I tested, It's OK for eTimer0, but NOK for eTimer1, SO is the configure different?

[PetrS]

Hi,

there should be no difference in eTimer channel setting, except of input signal/pin. Which pin do you use in fact and what is the config you have? 

BR, Petr
