Hello All,

I am using Stm32f2 controller. I have beeper connected to one of the GPIO pin of controller.
To genearte a beep sound, is it sufficeint that if i set this GPIO or should i provide a PWM input?
IF PWM input has to be provided , how can i do that?

I am new to this field
Could anyone anyone help me doing this

Thanks

 

It depends if the beeper is DC or AC.
