I'm trying to measure the duty-cycle of the 0-5V electrical PWM signal I have generated from the any source. How can I do this? Anyone can help me?

The process is described in detail in the Reference Manual, look for PWM input mode.
Don't forget to check the input pin in the pin definitions table of the Datasheet. If it's not marked as 5 Volt Tolerant (FT in the I/O Level column), then place a suitable voltage divider between the signal source and the input pin.

berendi , I reviewed the article you submitted but I couldn't create enough time to work. Can you share with me if you have code about this situation? – Nickname Nov 04 '18 at 17:08

1There are step-by-step instructions in the Reference Manual I've linked. I can't do it any better than that. – followed Monica to Codidact Nov 04 '18 at 20:21
