Piezo battery monitor

[virginprops]

Hi,

Ive succesfully set up my arm/disarm beep with a piezo buzzer using mega pirate but im a bit confused about the low voltage beeps.
Do i need a sensor to go with the piezo or will it just beep automatically since ive set :-

#define PIEZO_LOW_VOLTAGE   ENABLED

And if this is the case where can i adjust the actuall voltage it will beep at?

thanks

I';d be interested to hear what you did to get the buzzer working for arm/disarm. There';s a thread on here I was involved in getting the arm/disarm led and gps lock led working but failed to get the buzzer working.
Regarding your low voltage beep you will need the current/voltage sensor.

Hi,

Sorry for the late reply. For the arm/disarm i just connected onto pin 32 with the piezo. In my config i set:-

#define PIEZO   ENABLED   
#define PIEZO_LOW_VOLTAGE   ENABLED
#define PIEZO_ARMING      ENABLED

and

#define COPTER_LEDS ENABLED

and in define:-

#define PIEZO_PIN 32  (i imagine this is your problem? standard it wasnt set to 32)

hope this helps.

Excellent. Thanks for that. Although I had a mid air disarm on 3.0.1r2 yesterday so considering buying another apm to replace the last of my crius boards. :-(
