Recently, I lost my original pixhawk’s buzzer. So I get a new one from the local vendor, But the volume is not very loud, So I check the datasheet found the driver frequency should around 3KHz, Then I measured the FC’s buzzer output frequency is 1.7KHz, Is there anyway to change the output frequency?
Same problem here , my buzzer voice is very poor also it comes with pixhawk.
Just give up… I get myself new one…The code is too complicated to me
Decided to give up .
But something find new in code.
