MultiWii 2.2 buzzer bug

[Spencer]

Hi

when i put a buzzer on TXO pin it will beep permanetly (MultiWii 2.2).

Code: Select all

#define BUZZER
#define RCOPTIONSBEEP

On pin D8 it works, but i need D8 for AUX1.

Code: Select all

#define D8BUZZER

With MultiWii 2.1 the buzzer works fine on TXO pin.
Is it a general software bug or is it depending on my Nanowii 0.5?

Well know it's a small consolation, but it does not work on "HK MultiWii PRO Flight Controller w/MTK GPS Module" too.

It's because these boards has a different pin configuration.

(But use the Port command to setup your Buzzer. This will work.)

use the override.buzzerpin feature from config.h

use the override.buzzerpin feature from config.h

This function doesen't work on the HK Multiwii PRO board. Sso maybe it does not work on his board to

no. it works for all boards. YOU must find the correct pin and port commands for your hardware though.

Here is my Solution ... this will use "D8" [in this case PORT-H5] on "MultiWii Pro HK" for Buzzer

#define OVERRIDE_BUZZERPIN_PINMODE pinMode (8, OUTPUT); // use D8
#define OVERRIDE_BUZZERPIN_ON PORTH |= 1<<5
#define OVERRIDE_BUZZERPIN_OFF PORTH &= ~(1<<5);

Hi dorty!
Did you use any external transistor between the multiwii pro and the buzzer?
or did you connect it directly?
