Kc868 Read Pwm input

[huntleight]

Q1) Can i use digital input ports for PWM? If yes how can i define those pins ?  ---> can't
Q2) If you said no Q1 so which pins is free GPIO and how can i use it? I use serial port pins so i cannot use that pins.  --> you need check with ESP32 datasheet, which pins can use for PWM output.

I explained it wrong. I want to read pwm input. Which GPIO pin is free i dont know but i know i use all input and output ports and serial port for hmi. Which pin is free and how can i access it ? Can you explain with schemes if needed  ?
