S32K312 use ADC to measure external input PWM

[FRIDAY618]

Hi NXP community:

I can't find the PDB module when using the s32k312?

What should I do if I want to measure the amplitude of an external input PWM with a 5us delay after the rising edge of the PWM or at the high center point of the PWM?

Hi,

Thank you so much for your interest in our products and for using our community.

I must admit that your request is a bit strange, since normally the amplitude of an external PWM signal is known and at the same time it tends to be fixed.

However, you can implement a GPIO interrupt to start the eMIOS, acting as time base and perform an Analogue data capturing like in AN13767 (4.2.4 section).

Hope it helps you.

Have a nice day!
