I want to capture the frequency of the input signal.

Anybody know how to get input-capture demo for MPC55xx/MPC56xx ?

Hi,

For example you can use the eMIOS module in IPM/IPWM/SAIC modes or the eTimer’s channel capture feature, depends what device you are using. Read eMIOS and eTimer chapters in device Reference manual for more info.

Attached you have code snippets for eMIOS IPWM and eTimer implementations.
