Hello.
I would like to ask a question regarding PWM
We all know the theory of PWM, that through changing the duty cycle we can provide something akin a analog value through only digital outputs. For example I can change the brightness of a LED by connecting it to a digital pin outputing PWM and controlling its duty cycle. No problem there.
But what happens if I change the other parameter: the period of the PWM signal??? What effect will it have on the load??
(Say for example I change Fosc from 1MHz to 16 or 48MHz)
