Buzzer constant sound

[fgrs]

not sure whats going one I have finally managed to connect the buzzer and lights but the buzzer is always on unless I turn the beeper ON from the radio it starts beeping which is fine it also beeps during calibration but feels like the buzzer sound is inverted, anyone have any idea?

these are mine settings crius AIO v2 connected to A2 instead of pin 32

Code: Select all

#define OVERRIDE_BUZZERPIN_PINMODE          pinMode (A2, OUTPUT); // use A2 instead of d8
#define OVERRIDE_BUZZERPIN_ON               PORTF |= 1<<2 //PORTB |= 1;
#define OVERRIDE_BUZZERPIN_OFF              PORTF &= ~(1<<2); //PORTB &= ~1;

Hi,

You can check the changes I made into the 2.3 code here http://www.multiwii.com/forum/viewtopic.php?f=8&t=4482. I also had the same problem with the buzzer being inverted but with a few changes in the code it was solved.

it was easier to make changes in the config only, had to swap those lines only

Code: Select all

  //#define OVERRIDE_BUZZERPIN_ON               PORTF |= 1<<2 //PORTB |= 1;
  #define OVERRIDE_BUZZERPIN_ON              PORTF &= ~(1<<2); //PORTB &= ~1;
  //#define OVERRIDE_BUZZERPIN_OFF              PORTF &= ~(1<<2); //PORTB &= ~1;
  #define OVERRIDE_BUZZERPIN_OFF               PORTF |= 1<<2 //PORTB |= 1;

Yep, the way you did it's easier.
