Hi all,

May I know how do I generate different tones on a buzzer using PIC16F877?
Is it necessary to use the PWN registers or CCP registers? I'm totally clueless here as this is the first time I'm doing it. Also the language to be written in is C.

Thanks for viewing.

 

You can use the PWM. By changing the duty cycle you will control the loudness and by changing the frequency you will change the tone sound.

 

Erm how do I change the frequency and what does CCPR1L and CCP1CON<5:4> means?

 

Which C compiler are you using?

 

IAR Embedded Workbench

I am not familiar with this one. Regarding the registers you mentioned before you can find their use in the datasheet.

 

Ok thanks for your help.
